Rated In = 63 A, it ships with a TM120M thermal-magnetic trip unit set for starter protection; note the 'without overload protection' qualifier means the thermal element is omitted, leaving only the magnetic short-circuit pickup adjustable from 5 to 15 times In. That makes this breaker a pure short-circuit protector for a motor starter combination — the overload relay handles the thermal protection separately. The adjustable short-circuit pickup (5–15 x In = 315–945 A magnetic trip) lets you coordinate with downstream motor starters and avoid nuisance trips on inrush. Two HQ auxiliary switches provide status feedback to the PLC or HMI.","metaTitle":"Siemens 3VA1163-5MH36-0BC0 Circuit Breaker, 55kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-5MH36-0BC0 circuit breaker, IEC frame 160, 55kA breaking capacity @ 415V, 63A, starter protection TM120M, UVR 24V DC.
