Description
Product Overview
The EtherWAN PD1044 4-Port Hardened Gigabit PoE Surge Protection Device provides inline protection against transient electrical surges for compatible Ethernet and Power over Ethernet networks. Featuring four 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 surge-current protection, 30 A line-to-line protection, 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 PD1044 is a four-channel hardened Gigabit Ethernet and PoE-compatible RJ45 surge protection device, manufacturer part number PD1044 and product code 1864390. It provides four numbered RJ45 IN connectors and four matching RJ45 OUT connectors, forming four 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 nominal discharge current and 30 A line-to-line nominal discharge current at an 8/20-microsecond waveform, with clamping voltages of 600 V line-to-ground and 20 V line-to-line. Response time is 5 ns. The aluminum IP30 enclosure measures 40 × 100.5 × 81.55 mm (W × H × D), weighs approximately 320 g, and supports DIN-rail or wall/panel mounting. The operating temperature range is -40°C to +75°C. A protective grounding connection is required. The PD1044 passes through Ethernet signals and compatible PoE power but does not function as an Ethernet switch, PoE injector, or power supply. EtherWAN lists the product as available only in North America and places surge protection devices in its three-year manufacturer warranty category, subject to applicable terms and exclusions.
Four Independent Gigabit RJ45 Protection Channels
The PD1044 protects up to four separate Ethernet cable runs using four numbered RJ45 IN connections and four corresponding RJ45 OUT connections. Each matched pair provides an independent inline protection path for compatible 10BASE-T, 100BASE-TX, and 1000BASE-T networks. This arrangement supports multiple Ethernet devices within the same equipment cabinet without functioning as a network switch 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 relevant to supported IP cameras, wireless access points, and other PoE-powered network devices. The PD1044 does not generate, inject, or increase PoE power; a compatible upstream PoE switch or injector must provide the required power.
10 kA Line-to-Ground Surge Protection
EtherWAN specifies a nominal line-to-ground discharge current of 10 kA using an 8/20-microsecond surge waveform. The manufacturer also lists 200 A line-to-ground discharge current under a 10/1000-microsecond waveform. These ratings describe performance under specified electrical test conditions. Proper grounding is essential, and the protector cannot guarantee immunity from direct lightning strikes or every possible surge event.
Dedicated Line-to-Line Surge Protection
In addition to its line-to-ground protection path, the PD1044 provides line-to-line surge protection rated at 30 A under an 8/20-microsecond waveform. EtherWAN lists clamping voltages of 20 V line-to-line and 600 V line-to-ground. These ratings represent different protection modes and must be evaluated separately when selecting surge protection for sensitive network equipment.
5 ns Response with Gigabit Ethernet Support
The manufacturer 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 system designers evaluate Gigabit Ethernet signal compatibility. EtherWAN recommends Category 6 cabling, while its installation guide specifies Category 5e or better.
Hardened IP30 Aluminum Enclosure and Flexible Mounting
The PD1044 features a rugged aluminum enclosure rated for operation from -40°C to +75°C. DIN-rail and wall/panel mounting options allow installation in suitable industrial network and control cabinets. Its compact 40 × 100.5 × 81.55 mm housing weighs approximately 320 g. The IP30 rating is not waterproof, so outdoor or moisture-exposed installations require an appropriately rated protective enclosure and a suitable grounding arrangement.

What is the EtherWAN PD1044 used for?
The EtherWAN PD1044 is a four-channel hardened RJ45 surge protection device designed for compatible Gigabit Ethernet and Power over Ethernet network connections. It helps limit exposure to specified electrical surges traveling through Ethernet cabling when properly installed and grounded. It provides inline surge protection rather than Ethernet switching or PoE power generation.
How many Gigabit Ethernet connections can the PD1044 protect?
The PD1044 protects four independent Ethernet cable runs. It provides four numbered RJ45 IN connectors and four corresponding RJ45 OUT connectors, forming four protected pass-through channels. Each connection must use the matching numbered port pair. The device does not operate as an Ethernet switch or share network traffic between its channels.
Does the EtherWAN PD1044 support 90W PoE++?
Yes. EtherWAN lists IEEE 802.3af, 802.3at, and 802.3bt compatibility, including high-power PoE pass-through up to 90W. The PD1044 allows compatible Ethernet data and power to pass through its protected RJ45 connections. It does not supply PoE power itself, so the connected PoE switch or injector must provide the required electrical power.
What are the PD1044 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 under an 8/20-microsecond surge waveform. It also lists 200 A line-to-ground current under a 10/1000-microsecond waveform and a 5 ns response time. The line-to-ground and line-to-line ratings apply to different protection paths and must not be treated as interchangeable.
Does the PD1044 require grounding, and how should it be connected?
Yes. Proper grounding is required for effective surge protection. The PD1044 has a grounding screw on top of its housing, and EtherWAN identifies a grounding cable in the installation package. Ethernet cable runs must use matching numbered RJ45 IN/OUT port pairs. The device supports bidirectional protection. Follow the manufacturer's installation guide and applicable site grounding requirements, and consider protection at both ends of a cable when both connected devices are exposed.
Can the EtherWAN PD1044 be installed in an outdoor equipment cabinet?
The PD1044 operates from -40°C to +75°C, making it suitable for compatible installations with demanding temperature conditions. However, its IP30 aluminum enclosure is not waterproof. Outdoor or moisture-exposed deployments require an appropriately rated protective cabinet, correct grounding, and suitable cable routing. EtherWAN also specifies a maximum total Ethernet installation path of 100 meters between connected network devices.
What is the difference between EtherWAN PD1044 and PD1042?
The EtherWAN PD1044 provides four protected Gigabit RJ45 Ethernet channels, while the PD1042 provides two. Both support IEEE 802.3af/at/bt PoE pass-through up to 90W and share the published 10 kA line-to-ground and 30 A line-to-line surge-current ratings under an 8/20-microsecond waveform. The PD1044 measures 40 × 100.5 × 81.55 mm and weighs 320 g, so selection should account for the number of required protected cable runs and available cabinet space.
