Un dispositivo che chiude per bloccare l'accesso ai principali si disconnette quando l'interruttore è disconnesso, test o posizione ritirata.
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
The current sensing element within the circuit breaker which provides the sensing function for that circuit breaker.
Industry:Electrical equipment
A device that closes to block access to the main disconnects when the circuit breaker is in the disconnected, test or withdrawn position.
Industry:Electrical equipment
A barrier which provides phase-to-phase or phase-toground isolation.
Industry:Electrical equipment
An internal mechanical system which opens and closes the circuit breaker contacts.
Industry:Electrical equipment
An indicating means which displays the position (open or closed) of the main contacts.
Industry:Electrical equipment
A current transformer which encircles the neutral conductor; required on circuit breakers with ground-fault protection, when applied on a grounded system.
Industry:Electrical equipment
A qualifying term indicating there is purposely introduced a delay in the tripping action of the circuit breaker, which delay decreases as the magnitude of the current increases.
