The Siemens 3VA1063-4ED36-0KH0 is a 3-pole IEC molded-case circuit breaker in the 3VA1 frame 100 series, rated 63 A continuous (In) with fixed TM210 thermal-magnetic overload protection (Ir = 63 A) and fixed short-circuit pickup at Ii = 10 × In.
Integrated accessories and wiring
The shunt trip lets a remote safety relay or PLC drop the breaker under emergency conditions; the alarm switch signals a trip event back to the control system. All connections are clamp-type — spring-cage terminals that accept solid or ferruled stranded copper without lugging, which speeds panel wiring and reduces torque-check time.
