Circuit Protection

What is a Circuit Protection device?

A circuit protection device is a fail-safe device that originates a disruption in an electrical circuit when it recognizes an excess and unsafe power load in a circuit. The main aims of circuit protection are to localise and isolate the situation or fault and avert and minimize any unnecessary power loss.

What Do We Supply?

We have broad selection of circuit protection devices, including:
Circuit breakers
Thermal circuit breakers
Thermal-magnetic circuit breakers
Magnetic circuit breakers
Hydraulic-magnetic circuit breakers
Fuses
LV fuse links
LV fusegear
