Motor protection MCCB with integrated undervoltage release
The Siemens SENTRON 3VA2220-5MN32-0BH0 is a 3-pole molded case circuit breaker (MCCB) specifically designed for motor protection, rated at 200 A continuously across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling.
Rated current and thermal performance
Maximum power loss is 46 W, which informs enclosure ventilation requirements when grouping multiple breakers.
Rated ultimate short-circuit breaking capacity (Icu) is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 5.2 kA at 690 V — the steep drop above 500 V means verify system voltage against the curve before specifying.
Protection and monitoring functions
A trip indicator provides local visual confirmation of a fault event without needing to open the panel door.
Physical dimensions and mounting
Dimensions are 181 mm high, 105 mm wide, and 86 mm deep — a standard SENTRON 3VA2 footprint that fits existing panel cutouts and busbar arrangements for 200 A frames.
