This is known as a shunt trip circuit breaker. If its terminals are identified. It is useful in situations where the inspector is unable to physically reach a circuit breaker.
In The Case Of Elevators, A Shunt Trip Breaker Is Installed So That The Fire Alarm Can Send A Signal To The Shunt Trip.
Shunt trip, as mentioned, is an additional element of the circuit protection device. Connect your breaker’s shunt trip attachment. The main difference between a shunt trip and an undervoltage release is that the shunt trip opens the circuit breaker when a control voltage is applied to its coil.
Let’s Discuss The Connection Procedure:
A shunt trip button is a device that allows an inspector to trip a circuit breaker without physical contact. Feed the wires into the holes close to the shunt trip after placing the insulator in the appropriate location. An alternative is to link a shunt trip to an exterior remote switch.
Some Circuit Breakers Allow Shunt Trip Kits To Be Installable In The Field.
The shunt release is essentially an opening coil plus a release. A shunt trip breaker can be a single, two or three pole breaker. A shunt trip is an optional accessory device that electricians and/or manufacturers install to a circuit breaker.
The Inspector Simply Presses The Button And It Trips The Breaker.
The cb has thermal/magnetic trip capabilities, but it also has the ability to trip electronically say from a feeder protection relay say like the ge sr750. Apply a specified voltage to the shunt trip coil, and the circuit breaker will trip and open. This switch can be turned off by pressing a button;
Thermal Trip And Electromagnetic Trip Also Use This Trip Unit.
This is known as a shunt trip circuit breaker. Thermal release of a circuit breaker. It is generally controlled through normally open contact.
