Surge Protective Devices Meet UL 1449 Third Edition Standard
Built with TPMOV surge suppression technology, Ferraz Shawmut’s new Surge-Trap surge protective devices (SPDs) comply with the UL 1449 Third Edition standard. The units exhibit modular-style IP-20-grade “finger-safe” protection, and mounts on a DIN rail to safeguard critical electrical system components from transient overvoltage effects. The devices suit system voltages from 120 V to 600 V, and are MCOV rated from 180 V to 550 V. The SPDs demonstrate a short circuit current rating (SCCR) of 100 kA and a surge capacity rating per mode of 20 kA 8/20 µs. The products are approved for Type 1 and 2 applications, including AC/DC power distribution, high-voltage power supplies, telecommunications equipment, PLC applications, electronic motor controllers and starters, medical equipment, and UPS and security systems.
