These circuit breakers have been brilliantly engineered to perfection as the tripping mechanism has been built in such a way that any sudden over current will cause the 1 poles and all of the poles in 2 and 3 pole Circuit Breakers to trip simultaneously. Furthermore, each pole included in the mechanism has a thermal-magnetic trip element that is precisely calibrated for 40c temperature.

Trip indication

This circuit breaker has a Visi-trip® which provides a visual indication when the circuit breaker has tripped. Whenever the circuit breaker trips the handle that is located at the center of the breaker will respond in such a manner that it will assume a center position and the indicator will appear in a window indicating that a circuit breaker has tripped.

This window will only appear when a breaker has tripped and can easily be rectified by merely turning the handle to off or on. This Visi-trip® indicator is currently the only trip indicator in the market and it has helped achieve the high market share that OOB circuit breakers have in the market today.
