The breaking capacity is Icu = 16 kA at 415 V, which places it in breaking capacity class B — sufficient for most industrial distribution panels where fault currents stay under that threshold. This variant includes a shunt trip (STL) coil rated for 110–127 V DC or AC 50/60 Hz, plus two auxiliary switches (HQ). The clamp-type terminals accept copper conductors without lug kits, which speeds panel wiring. The fixed Ir means no adjustment dial on the front — the overload curve is locked at 50 A, so confirm the continuous load matches before specifying. The shunt trip coil draws its control voltage from a separate 110–127 V supply — verify polarity on DC circuits; the coil is polarity-sensitive. Two auxiliary switches (HQ) are built in, providing status feedback for the open/closed position. These are rated for the control circuit voltage and can be wired into a PLC digital input or a status lamp circuit without an interposing relay.","metaTitle":"Siemens 3VA1050-2ED36-0JC0 Circuit Breaker, 50A, 16kA @ 415V","metaDescription":"Siemens 3VA1050-2ED36-0JC0 IEC frame 100 circuit breaker, 50A fixed TM210 overload, 16kA breaking capacity @ 415V.
