Why Choose the Mersen STMT23-6K30V-SP-S Surge Protection Device?
The Mersen 83230504 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 provides reliable protection for sensitive control, communication and power supply equipment where DIN rail space is limited.
Designed for DIN rail installation, this monobloc surge protection device protects connected equipment against voltage spikes caused by lightning activity, switching operations and electrical disturbances. Its slim one-module construction makes it ideal for compact control panels, machinery cabinets and distribution boards.
With a maximum discharge current of 6 kA (8/20 μs), a 30 V AC maximum continuous operating voltage (Uc) and a 24 V AC nominal operating voltage, the Mersen 83230504 is ideal for protecting low voltage control circuits, automation equipment, communication systems and instrumentation.
