Description
Product Overview
The EtherWAN PD3041 Hardened Surge Protection Device provides transient overvoltage protection for DSL and compatible two-wire copper communication lines. Featuring RJ11 and terminal-block connection options, it protects against conductor-to-conductor and conductor-to-earth electrical surges in properly installed communication systems. The PD3041 supports a total surge-current rating of 10 kA using an 8/20-microsecond waveform, response times of 100 nanoseconds or less, and a maximum continuous operating voltage of 185 VDC. Its compact aluminum housing, DIN-rail mounting capability, and -40°C to +75°C operating temperature range make it suitable for industrial telecommunications cabinets and protected infrastructure installations.
The EtherWAN PD3041 is a hardened surge protection device designed for DSL and two-wire copper communication circuits. EtherWAN specifies RJ11 or two-wire terminal-block connections, conductor-to-conductor and conductor-to-earth protection, a total surge current of 10 kA at 8/20 microseconds, and nominal discharge surge-current ratings of up to 5 kA for each protection mode. Its maximum continuous operating voltage is 185 VDC, nominal operating current is limited to 380 mA at 25°C, and specified response time is 100 ns or less. The device uses an IP20 aluminum enclosure measuring 30 × 62.5 × 100 mm (W × H × D) and weighing approximately 184 g. It supports DIN-rail or desktop installation and operates from -40°C to +75°C. EtherWAN identifies UL 497B and IEC 61643-21 among its applicable standards. The RJ11 and terminal-block interfaces must not be used simultaneously, and correct grounding is essential. The PD3041 is not specified as an RJ45 Gigabit Ethernet or PoE surge protector. EtherWAN lists a three-year warranty category for surge protection devices, subject to its published warranty conditions and exclusions. Contact Coremicro for compatibility, product availability, and purchasing information.
RJ11 and Two-Wire Terminal-Block Protection
The PD3041 protects compatible DSL and two-wire copper communication lines through an RJ11 connector or a two-wire terminal-block interface. These alternative connection methods support different telecommunications wiring arrangements. EtherWAN's installation guide requires installers to select one connection method at a time; RJ11 and terminal-block connections must not be used simultaneously.
Conductor-to-Conductor and Earth Surge Protection
The device provides protection between the two communication conductors and between the conductors and earth. These protection modes help limit specified transient overvoltages caused by electrical disturbances, switching events, or induced surges. Correct grounding, circuit selection, and installation are necessary. The PD3041 does not guarantee protection against direct lightning strikes or every possible electrical event.
10 kA Total Surge-Current Capacity
EtherWAN specifies a total surge-current rating of 10 kA using an 8/20-microsecond waveform. The manufacturer separately lists nominal discharge surge-current values up to 5 kA for conductor-to-conductor and conductor-to-earth protection. These ratings apply to defined surge-test conditions and must not be interpreted as continuous line-current capacity.
Fast Response and Defined Voltage Limits
The PD3041 has a specified surge response time of 100 ns or less, with a maximum continuous operating voltage of 185 VDC. Its electrical specifications also identify a nominal line-current limit of 380 mA at 25°C, residual-voltage limits, and series resistance of 3.3 ohms ±10%. Installers must confirm that these characteristics are suitable for the protected communication circuit.
Compact DIN-Rail or Desktop Installation
The PD3041 supports DIN-rail mounting or placement in a suitable desktop or equipment-cabinet installation. Its aluminum housing measures 30 × 62.5 × 100 mm and weighs approximately 184 g. For DIN-rail installations, EtherWAN specifies grounding through a properly grounded DIN-rail rack. Other mounting arrangements use the dedicated grounding screw and suitable grounding wire.
Hardened Temperature Range and Telecom Standards
The surge protector operates from -40°C to +75°C and supports storage temperatures from -40°C to +85°C. EtherWAN identifies UL 497B, IEC 61643-21, CE, FCC Part 15 Class B, and VCCI in its product specifications. The IP20 housing requires protection against moisture and unsuitable outdoor exposure, even when ambient temperatures fall within the operating range.

What is the EtherWAN PD3041 surge protector used for?
The EtherWAN PD3041 is a hardened surge protection device designed for DSL and compatible two-wire copper communication lines. It provides conductor-to-conductor and conductor-to-earth protection against specified transient overvoltages. The device supports RJ11 or two-wire terminal-block connections and can be installed in suitable, properly grounded equipment cabinets.
What is the surge-current rating of the EtherWAN PD3041?
EtherWAN specifies a total surge-current rating of 10 kA using an 8/20-microsecond waveform. The manufacturer also lists nominal discharge surge-current ratings up to 5 kA for conductor-to-conductor and conductor-to-earth protection. These values describe defined surge-test conditions and do not represent continuous operating current or guaranteed protection against every electrical event.
Can the PD3041 protect RJ45 Gigabit Ethernet or PoE equipment?
The PD3041 is intended for RJ11 and two-wire copper communication lines, not standard RJ45 Gigabit Ethernet connections. EtherWAN does not specify Gigabit Ethernet or PoE surge protection for this model. EtherWAN offers separate RJ45 surge protectors, including the PD1041, with different electrical and interface requirements. Select a protector that matches the actual communication circuit.
Can the RJ11 and terminal-block connections be used simultaneously?
No. EtherWAN's installation guide specifies that installers must use either the RJ11 interface or the terminal-block interface, but not both at the same time. The incoming communication line must connect to the indicated input side, while the equipment being protected connects to the designated output side. Follow the manufacturer's wiring instructions and relevant electrical requirements.
How should the EtherWAN PD3041 be grounded?
For DIN-rail installations, EtherWAN specifies grounding through the DIN-rail rack, which must be properly bonded to the site's grounding system. For other mounting arrangements, the device provides a dedicated grounding screw for a suitable grounding wire. Proper grounding is essential for the intended surge protection function and must follow the manufacturer's instructions and applicable electrical codes.
Can the PD3041 be installed in an outdoor network cabinet?
The PD3041 operates from -40°C to +75°C, but its IP20 aluminum housing is not waterproof. Outdoor or moisture-exposed installations require an appropriately rated protective enclosure. The complete installation must also provide correct grounding, suitable wiring, environmental protection, and compatibility with the connected communication circuit.
What manufacturer warranty applies to the EtherWAN PD3041?
EtherWAN lists a three-year warranty period for surge protection devices in its published warranty policy. However, the policy also includes a general exclusion for spare parts, accessories, and peripherals. Applicable PD3041 coverage should therefore be confirmed before purchase. Additional exclusions include damage caused by improper installation, misuse, and natural disasters such as lightning strikes. Contact Coremicro for current warranty and purchasing details.
