Application example
Electrical interlocking of two 3VA molded case circuit breakers with undervoltage releases
Q 1 Molded case circuit breaker 1
UVR1 Undervoltage release in molded case circuit breaker 1
AUX1 Auxiliary switch in molded case circuit breaker 1
Q2 Molded case circuit breaker 2
UVR2 Undervoltage release in molded case circuit breaker 2
AUX2 Auxiliary switch in molded case circuit breaker 2
The undervoltage release UVR must not be connected to phases L1 and L3 for 690 V AC
applications. In this case, it is connected to phase L1 and the N conductor or to a control
voltage supply up to maximum 480 V AC.
