TOMZN 2P DC Solar Mini Circuit Breaker-TOB7Z-63-1000V

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.
