Description
Product Overview
The EtherWAN PD1042 2-Port Hardened Gigabit PoE Surge Protection Device provides inline protection against transient electrical surges for compatible Ethernet and Power over Ethernet networks. Featuring two independent RJ45 pass-through channels, it supports 10/100/1000BASE-T Ethernet and IEEE 802.3af/at/bt PoE connections with power pass-through up to 90W. EtherWAN specifies 10 kA line-to-ground discharge current, 30 A line-to-line discharge current, and a 5 ns response time under defined test conditions. Its rugged IP30 aluminum enclosure, DIN-rail or wall/panel mounting options, and -40°C to +75°C operating temperature range make it suitable for properly grounded industrial networking cabinets, IP surveillance installations, and protected infrastructure environments.
The EtherWAN PD1042 is a two-channel hardened Gigabit Ethernet and PoE-compatible RJ45 surge protection device, manufacturer part number PD1042 and product code 1864389. It provides two RJ45 IN connectors and two corresponding RJ45 OUT connectors, forming two independent protected Ethernet cable paths. Supported networking standards include IEEE 802.3 10BASE-T, 100BASE-TX, and 1000BASE-T, along with IEEE 802.3af, 802.3at, and 802.3bt PoE pass-through up to 90W. EtherWAN specifies 10 kA line-to-ground discharge current and 30 A line-to-line discharge current using an 8/20-microsecond waveform. Clamping voltages are 600 V line-to-ground and 20 V line-to-line, with a specified response time of 5 ns. The IP30 aluminum enclosure measures 32 × 103.5 × 81.55 mm (W × H × D), weighs approximately 140 g, and supports DIN-rail or wall/panel installation. Operating temperature is -40°C to +75°C. Proper grounding is required, and corresponding numbered RJ45 input and output ports must be paired correctly. The device does not switch Ethernet traffic or generate PoE power. EtherWAN lists PD1042 as available only in North America and places surge protection devices in its three-year manufacturer warranty category, subject to applicable conditions and exclusions.
Two Independent Gigabit RJ45 Protection Channels
The PD1042 protects two separate Ethernet cable runs using two numbered RJ45 IN connections and two corresponding RJ45 OUT connections. Each matched pair provides an independent pass-through protection path for compatible 10BASE-T, 100BASE-TX, and 1000BASE-T networks. This configuration supports connections to switches, IP cameras, wireless equipment, and other Ethernet devices without performing network switching or distributing traffic between channels.
IEEE 802.3bt PoE Pass-Through up to 90W
The surge protector supports compatible Power over Ethernet connections under IEEE 802.3af, 802.3at, and 802.3bt standards. High-power PoE pass-through up to 90W makes it suitable for supported IP surveillance equipment, wireless access points, and other PoE-powered networking devices. The PD1042 does not generate, inject, or increase PoE power. An appropriate upstream PoE switch or injector must supply the required power.
10 kA Line-to-Ground Surge Protection
EtherWAN specifies a nominal line-to-ground discharge current of 10 kA under an 8/20-microsecond surge waveform. The manufacturer also lists 200 A line-to-ground discharge current under a 10/1000-microsecond waveform. These values describe the protector's performance under defined electrical tests. Proper installation and grounding are necessary, and no surge protection device can guarantee immunity to direct lightning strikes or every possible electrical event.
Dedicated Line-to-Line Surge Protection
In addition to line-to-ground protection, the PD1042 provides line-to-line surge protection rated at 30 A using an 8/20-microsecond waveform. EtherWAN specifies clamping voltages of 20 V line-to-line and 600 V line-to-ground. These separate electrical ratings help engineers evaluate the protection requirements of connected networking equipment. The 10 kA line-to-ground rating must not be interpreted as the line-to-line discharge capacity.
5 ns Response with Gigabit Signal Compatibility
EtherWAN specifies a 5 ns response time for transient surge events. Published signal characteristics include 1 dB insertion loss at 10 MHz and 100 MHz, -20 dB return loss at those frequencies, and capacitance of 1 pF or less for both protection paths. These specifications help network engineers assess signal compatibility when adding surge protection to Gigabit Ethernet links. Category 6 cabling is recommended, with Category 5e or better required by the installation guide.
Compact Hardened IP30 Aluminum Enclosure
The PD1042 features a rugged aluminum enclosure measuring 32 × 103.5 × 81.55 mm and weighing approximately 140 g. DIN-rail and wall/panel mounting options support integration into suitable networking and industrial control cabinets. Its -40°C to +75°C operating temperature range accommodates demanding thermal environments, but the IP30 enclosure is not waterproof. Outdoor or moisture-exposed installations require an appropriately rated protective cabinet.

What is the EtherWAN PD1042 used for?
The EtherWAN PD1042 is a hardened two-channel RJ45 surge protection device designed for compatible Gigabit Ethernet and Power over Ethernet connections. It helps limit exposure to specified electrical surges traveling through Ethernet cabling when properly installed and grounded. It provides inline protection rather than Ethernet switching or PoE power generation.
How many Gigabit Ethernet connections can the PD1042 protect?
The PD1042 protects two independent Ethernet cable runs. It features two numbered RJ45 IN connectors and two corresponding RJ45 OUT connectors, creating two protected pass-through channels. Each cable connection must use a matching numbered pair. The device does not function as an Ethernet switch or distribute network traffic between its connectors.
Does the EtherWAN PD1042 support 90W PoE++?
Yes. EtherWAN specifies IEEE 802.3af, 802.3at, and 802.3bt compatibility, including high-power PoE pass-through up to 90W. The PD1042 allows compatible Ethernet data and power to pass through its protected RJ45 connections. It does not supply PoE power, so an upstream PoE switch or injector must provide the required electrical power.
What are the PD1042 surge-current ratings and response time?
EtherWAN specifies 10 kA nominal line-to-ground discharge current and 30 A nominal line-to-line discharge current using an 8/20-microsecond waveform. It also lists 200 A line-to-ground current under a 10/1000-microsecond waveform and a 5 ns response time. These are distinct electrical test ratings and should not be treated as interchangeable or as guarantees against every possible surge event.
Does the PD1042 require grounding, and how should it be connected?
Yes. Proper grounding is essential for the PD1042 to provide effective surge protection. EtherWAN identifies a grounding screw on top of the housing and includes a grounding cable with the installation hardware. Connect each Ethernet cable run through matching numbered RJ45 IN/OUT ports. The device supports bidirectional protection. Follow the manufacturer's installation guide and applicable grounding requirements, and use protectors at both cable ends when both connected devices need protection.
Can the EtherWAN PD1042 be installed in an outdoor equipment cabinet?
The PD1042 operates from -40°C to +75°C, supporting compatible installations with demanding temperature conditions. However, its IP30 aluminum housing is not waterproof. Outdoor or moisture-exposed installations require an appropriately rated protective cabinet, correct grounding, and suitable cable routing. EtherWAN's installation guide also specifies a maximum total Ethernet cable path of 100 meters between connected network devices.
What is the difference between EtherWAN PD1042 and PD1044?
The EtherWAN PD1042 protects two independent Gigabit RJ45 Ethernet channels, while the PD1044 protects four. Both support IEEE 802.3af/at/bt PoE pass-through up to 90W and have the same published 10 kA line-to-ground and 30 A line-to-line surge-current ratings under an 8/20-microsecond waveform. The PD1042 is the smaller model, measuring 32 × 103.5 × 81.55 mm and weighing approximately 140 g. The PD1044 measures 40 × 100.5 × 81.55 mm and weighs approximately 320 g.
