Any isolated problem in your electrical circuit can bring the whole circuit crashing down and damage your precious electrical equipment. To protect against electrical faults from bringing down the whole system, you should install a reliable circuit breaker like the New General Electric THQB2115GFT Circuit Breaker. The bolt-on circuit breaker is easy to install and offers superior ground fault protection to keep your electrical appliances safe. The single-phase circuit breaker is specifically designed to be used with AC circuits. It has an instantaneous trip function, which is activated automatically when the current flowing in the circuit exceeds a certain threshold value. This breaker switch has a voltage and current rating of 240-Volt and 15-Ampere respectively.
