SMX+OF Shunt Trip Unit & Auxiliary Contact of MCB MCCB Series Circuit Breaker Accessory
1. This Auxiliary contact is to be installed in left side of relative series products(such as MCB, RCCB, RCBO), with function of auxiliary contact, remote shunt tripper, and under-voltage.
2. Auxiliary contact: linked with ON, OFF mechanism, of main circuit of circuit breaker, mainly used for indication of circuit breaker ON, OFF status. To connect it into control circuit of breaker, through ON and OFF of circuit breaker, the auxiliary contact can take control or interlock to related electrical device.
3. Shunt tripper: It's s tripper used for voltage source excitation. Its own voltage can be independent from the voltage of main circuit. So shunt tripper is an auxiliary of remote control tripping, can disconnect circuit by remote, to liaison with fire alarm system. Can also remote control to trip off by Emergency stop button.
4. Under-voltage tripper: It's a tripper to trip off circuit breaker, when its terminal voltage drop lower to a certain specified scope. Thus to protect the electrical equipment under circuit breaker, which is in loading circuit, from the loss of under-voltage.
5. Shunt tripper+auxiliary contact: with function of shunt tripper and auxiliary contact at the same time.
6. Under-voltage tripper+auxiliary contact: with function of under-voltage and auxiliary contact at the same time.
