Why Choose the Mersen 83230502 Surge Protection Device?
The Mersen 83230502 is a compact Type 2+3 Surge Protection Device (SPD) designed to protect low voltage AC and DC electrical installations against transient overvoltages. Part of the Mersen Surge-Trap® Monobloc STMT23 Series, this slim SPD is ideal for protecting sensitive control, communication and power supply equipment where DIN rail space is limited.
Designed for DIN rail installation, this monobloc surge protection device provides effective protection against voltage spikes caused by lightning activity, switching operations and electrical disturbances. Its slim single-module construction allows straightforward installation in compact control panels, machinery cabinets and distribution boards.
With a maximum discharge current of 6 kA (8/20 μs), a 150 V AC maximum continuous operating voltage (Uc) and a 1 phase + neutral SP TT/TNS configuration, the Mersen 83230502 is ideal for protecting 120 V AC control circuits and sensitive low voltage electrical equipment.
