The TM120M thermal-magnetic trip unit provides starter protection: the thermal element tracks motor heating curves, while the magnetic short-circuit pickup is adjustable from 5 to 15 x In. It ships with a factory-installed shunt trip (STL) rated 220–250 V DC or 208–277 V AC, plus a nut keeper kit for secure terminal retention — both reduce field assembly steps. The adjustable Ii range (5–15 x In) lets you set the magnetic trip high enough to avoid nuisance trips on motor inrush while still protecting the cable against bolted faults. The shunt trip coil draws on the control circuit (220–250 V DC or 208–277 V AC); verify the control transformer and fuse sizing can support the inrush without dropping below the dropout voltage of the coil.","metaTitle":"Siemens 3VA1110-5MH32-0KA0 Circuit Breaker, 100A, 55kA @ 415","metaDescription":"Siemens 3VA1110-5MH32-0KA0 IEC frame 160 MCCB, 100A, 55kA breaking capacity @ 415V AC.
