TOMZN AC SPD 4P House Surge Protector Low-voltage Arrester Device 20KA~40KA 385V-TOV1-C

TOMZN AC SPD 4P Features

  • 4-Pole Surge Protection Device (SPD) – Designed to protect three-phase AC systems plus neutral from voltage surges and transient over voltages.

  • High Surge Current Handling – Built to absorb surge currents (typically around 20 kA–40 kA depending on rating) to protect equipment from lightning strikes and switching transients.

  • Designed for Low-Voltage AC Networks – Works with 230/400 V AC at 50/60 Hz, making it suitable for residential, commercial, and light industrial electrical panels.

  • Fast Response & Low Let-Through Voltage – Quickly clamps and diverts excess surge energy to ground, reducing the risk of damage to sensitive electronics.

  • DIN-Rail Mountable – Compact, DIN-rail design for easy installation in distribution boards and sub-panels.

  • Thermal Disconnect Protection – Often includes thermal disconnection mechanisms for added safety if internal components overheat.

  • Visual Status Indicators – Many models use simple status windows/LEDs (green for normal, red for fault) to show device health and when replacement is needed.

TOMZN AC SPD 4P House Surge Protector Low-voltage Arrester Device 20KA~40KA 385V-TOV1-C

The TOMZN AC SPD 4P TOV1-C is a four-pole surge protective device designed for 3-phase AC electrical systems. It protects electrical distribution boards and connected equipment from voltage surges, lightning-induced transients, and instantaneous over-voltage events by diverting excess energy away from sensitive components. Rated for 230/400 V AC at 50/60 Hz and compliant with the IEC/EN 61643-1 surge protection standard, this SPD offers high discharge capacity (typically 20 kA–40 kA on the “C” model) and fast response time to help enhance power quality and equipment reliability. Its compact DIN-rail mountable design, robust build, and visual status indicators make it suitable for residential, commercial, and industrial electrical panels where safeguarding against power spikes is essential.
