DC Surge Protector

Product catalog summary

Overview: This document outlines the technical specifications and installation guidelines for ASwich's DC Surge Protection Devices and DC Moulded Case Circuit Breakers, as well as the EDP series surge protective devices and EDFH series DC fuse holders, all designed for photovoltaic systems to ensure protection against overvoltage and surges.

Specifications:

DC Moulded Case Circuit Breakers: Models include EM3DP-250U/23-250, EM3DP-320U/33-320, and EM3DP-400U/43-400, with rated currents from 250A to 400A and operating voltages up to 1500V DC. They have a mechanical life of 10,000 cycles and an electrical life of 2,000 cycles, with an IP20 protection class.
DC Surge Protection Devices: The EDPG40 series is designed for the DC side of photovoltaic systems, with a maximum discharge current of 40kA and a nominal discharge current of 20kA, compliant with IEC 61643-31 and EN 50539-11 standards.
Surge Protective Devices: Classified as Class I+II / Type 1+2, these devices feature high energy MOVs, a pluggable design, and compliance with IEC 61643-31 and EN 50539-11+ A1. They support maximum continuous operating DC voltages of 600V, 1000V, and 1500V, with a nominal discharge current of 20kA and an impulse discharge current of 6.25kA.
DC Fuse Holder: Compliant with IEC 60947-3, these holders support a maximum rated voltage of 1000V and a maximum current of 30A, designed for short circuit and over-current protection in distribution systems.

Procedures and Installation:

Surge protectors can be installed on a 35mm standard guide rail, available in U, L, and Y connection types, with a pluggable design for easy maintenance and replacement. Indicators show green for normal operation and red for faults, with remote monitoring capabilities available.

Norms and Standards:

Compliance with IEC 60947-2, GB14048.2, and EN 50539-11 standards ensures high safety and performance levels. Devices are TUV and CE approved, indicating adherence to international safety and quality standards.

Recommendations:

For optimal performance, ensure installation in environments with temperatures ranging from -40°C to +70°C and relative humidity up to 95%. Regular monitoring and maintenance are recommended to ensure the devices function correctly and provide the necessary protection.

Product Benefits:

Reliable voltage protection level, super surge discharge capacity, safety overload capacity, fast response to overvoltage, and easy installation and replacement.

Additional Features:

Status indicator window: Green (normal), White (failure). Shaker terminal: Green (ok), White (failure).
