It is configured as a starter protection device, meaning it is designed to sit ahead of a motor starter or contactor, providing short-circuit and overload protection for the motor branch circuit. The TM120M thermal-magnetic release handles the overload curve and instantaneous trip; the shunt trip (STL) allows remote tripping from a PLC or emergency-stop circuit. Two HQ auxiliary switches (3VA9688-0BL30) are integrated for status feedback to the control system. At 415 V the rating drops to 121 kA, still well above typical industrial service-entrance levels. If your installation is on a 480 V wye or 400 V delta system, the 415 V figure governs; for 690 V wind-farm or mining applications the lower figure applies. Above that it steps down: 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. If the MCCB is mounted in a sealed enclosure or near heat-generating drives, use the 60 °C or 70 °C column for the actual continuous current the breaker will carry without nuisance tripping. The width of 105 mm is standard for a 200 A frame MCCB — it fits a typical 3-pole MCCB cutout in a panel or enclosure. The shunt trip coil draws power only during the trip event; verify the control voltage matches the STL rating before wiring. ## What it does not include It is a standalone thermal-magnetic breaker with a shunt trip and two auxiliary switches. If you need undervoltage protection or ground-fault sensing, you would select a different 3VA variant or add external relays.","metaTitle":"Siemens 3VA1220-5MH32-0HC0 MCCB, 200 A, 187 kA at 240 V","metaDescription":"Siemens SENTRON 3VA1220-5MH32-0HC0 molded case circuit breaker, 200 A rated, 187 kA at 240 V, 3-pole, starter protection, TM120M release, shunt trip.
