Dehn DR Modular Surge Protector 440V AC Maximum Surge Current 8kA DIN Rail Mount DR M 4P 255 FM

Dehn DR M 4P 255 FM is a modular surge protector designed for industrial and commercial electrical applications requiring protection against voltage surges up to 440V AC with a maximum surge current rating of 8kA. This Type 3 device mounts on a DIN rail and combines a base unit with a plug-in protection module to provide efficient and reliable protection.

The device utilizes a combination of varistor and spark gap technology to ensure high discharge current performance. It incorporates Thermo Dynamic Control for continuous status indication, allowing operators to monitor the condition of the surge protection device effectively without dismantling it.

The tool-less replacement capability of the protection plugs simplifies maintenance and testing, reducing downtime in critical infrastructure environments such as industrial manufacturing, commercial electrical distribution, and electronic equipment installations.

Operating reliably across a wide temperature range from -40°C to 80°C, the DR M 4P 255 FM complies with internationally recognized standards including KEMA, RoHS, VDE, and UL certifications. Its compact size (90 mm length, 66 mm height, 36 mm depth) enables versatile installation even in constrained electrical panels.

Voltage surges or spikes, often caused by electrical switching or lightning strikes, can severely damage sensitive electronic devices. This modular surge arrester provides an essential layer of protection in compliance with BS7671 Amendment 1 and BSEN 62305 standards for lightning and surge mitigation, making it ideal for industrial, laboratory, commercial, and HVAC applications.
