Explanation of Circuit Breaker Accessories

A circuit breaker is an electrical switch that is automatically operated and produced to act as a shield for an electrical circuit from damage. The damage can be caused by excess current from an overload or short circuit. Basically the basic function of a circuit breaker is to interrupt current flow after a fault is detected. But when operating a circuit breaker, it is important to maintain the accessories that are essential for its function. Electrically operated power circuit breakers can use many different accessories placed inside the breaker for remote indication and automatic operation. For an in depth look at different accessory parts, read the article below.

Circuit breaker accessories are suited to the control voltage of the machine and can be made ready in the form of factory-installed options or in a field-installed package form. Auxiliary switches supply a remote signal of the main contact position of the breaker. This can alter the position when the minimum insulation distance between the main contacts is attained. Normally the contacts form a bond with a common neutral. Other circuit breaker accessory parts can include the bell alarm. Also known as the overcurrent trip switch, this supplies another remote indication that signals if the circuit breaker has opened due to an electrical fault.The switch is turned on and from there, the output alters the state any time that the breaker is switched from an overcurrent or ground fault.

Meanwhile the electric lockout accessory is another accessory part for the circuit breaker. It utilizes a coil much like the undervoltage trip device in order to keep the breaker from shutting off, with the exception of it being energized. This way, the breaker can avoid being shut off until a control voltage is applied. For instance, two breakers can be linked so that they can’t both be shut off at the same time. The electric lockout coils on the two breakers to be interlocked can be wired in series with a normally closed Auxiliary Switch contact on the other breaker to provide the interlocking function. Mechanical bypass is used to permit cold startup when control power is not available.
