Products Introduction

This device blocks the power supply of load when a problem (over-current, over-voltage, earth leakage, flow in surge, etc.) occurs.

Auto Earth Leakage Breaker(SHAM-30ELB )device automatically returns the power supply after such problem is solved. It also features a surge protection device to minimize damage from power surges.

The SHAM-30ELB series models automatically disconnect power to the load under faults conditions, while devices are parallel connected that disconnected themselves from the load under fault conditions, leaving power to the load.

No operator intervention is required as they reset automatically and are completely maintenance free.

Uses the patent technology in module.
