It ships with a TM120M thermal-magnetic release set for starter protection — note that the TM120M provides short-circuit protection (adjustable Ii = 5–15 × In) but no overload protection, so a separate overload relay is required upstream for motor duty. A nut keeper kit is also included for panel mounting. ## Integration notes The shunt trip coil draws from a 110–127 V control supply — verify the control transformer rating and polarity before energizing. The two auxiliary switches and one trip alarm switch share the same terminal block; wire the alarm switch to the PLC digital input for remote trip indication.","metaTitle":"Siemens 3VA1112-5MH32-0JH0 Circuit Breaker, 125A, 55kA @ 415","metaDescription":"Siemens 3VA1112-5MH32-0JH0 IEC frame 160 MCCB, 3-pole, 125A, breaking capacity 55kA @ 415V.
