Why Choose the Mersen 83230501 Surge Protection Device?
The Mersen 83230501 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 sensitive control, communication and power supply equipment where space inside the panel is limited.
Designed for DIN rail installation, this monobloc surge protection device provides fine protection against voltage spikes caused by lightning activity, switching operations and electrical disturbances. Its slim one-module format allows easy installation in compact control panels, distribution boards and machinery cabinets.
With a maximum discharge current of 6 kA (8/20 μs), a 20 V AC maximum continuous operating voltage (Uc) and remote indication, the Mersen 83230501 is well suited for sensitive 12 V AC circuits requiring dependable surge protection and remote status monitoring.
