Type 2 DC Surge Protective Device with Remote Changeover Contact | DIN-Rail, IP20

Protect DC power supplies with proven, standards-compliant surge suppression.

This Type 2 DC surge protective device (SPD) shields sensitive DC power systems from transient overvoltages at the LPZ 0B–1 boundary and beyond. An integrated remote changeover contact (FM) enables straightforward status/alarm signaling to PLCs, BMS, or SCADA, supporting proactive maintenance and rapid fault notification.

Built for industrial panels and tight spaces.

Engineered for fast, clean installation on a 35 mm DIN rail per EN 60715, the unit occupies only 54 mm of rail space—ideal for dense control cabinets and retrofit projects. Its IP20 degree of protection (IEC/EN 60529) helps safeguard operators during panel work while maintaining compactness.

Certified performance and durability.

Compliance with IEC/EN 61643-11 ensures the device meets rigorous Type 2 SPD requirements for DC applications. Mechanical robustness is verified by vibration (DIN EN/IEC 60068-2-6) and shock (DIN EN/IEC 60068-2-27) test standards, while the enclosure material meets a flammability class of UL 97 V0. EAC certification supports deployment across relevant Eurasian markets.
