- Company Profile:
A graphical representation of the response of a circuit breaker to current over a period of time.
Industry:Electrical equipment
A static device with primary winding, connected in series with the conductor (bus) carrying the current to be measured or controlled within the switchgear.
Industry:Electrical equipment
Provides continuous temperature rise status of the wiring for a period of time both before and after the device trips. This allows the circuit breaker to respond to a series of overload conditions which would otherwise go undetected.
Industry:Electrical equipment
A general purpose term for circuit breakers that use bimetals and electromagnetic assemblies to provide both thermal and magnetic overcurrent protection.
Industry:Electrical equipment
A trip unit function that accurately maps the heating and cooling effects of load behavior on rated conductors to provide thermal protection without nuisance tripping.
Industry:Electrical equipment
A spring mechanism that is compressed or “charged” and then released or “discharged” to close the circuit breaker.
Industry:Electrical equipment
A motor which electrically charges the stored energy closing spring(s).
