The Siemens SENTRON 3VA2216-7MN32-0BH0 is a 3-pole molded case circuit breaker (MCCB) in the motor protection version, rated for 160 A continuous current at 40 °C ambient. It carries a breaking capacity of 330 kA at 240 V, stepping down to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V — covering high-fault installations where SCCR headroom matters. The ETU350M overcurrent release provides adjustable thermal-magnetic protection tailored for motor loads, with phase failure detection built in. An undervoltage release (UVR) is integrated, and the auxiliary contact block includes 2 auxiliary switches plus a trip alarm switch (HQ configuration). Rated insulation voltage is 800 V, and the breaker dissipates up to 75 W at full load. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. Mechanical endurance is rated at 20,000 operations.
Sourcing & Lifecycle
The integrated auxiliary trip (3VA9608-0BB11) and the supplied basic switch (3VA2216-7MN32-0AA0) are listed as companion components, ensuring replacement parts are traceable.
Integration Notes
Panel footprint: 105 mm wide × 181 mm high × 86 mm deep. The 3-pole form factor fits standard MCCB mounting in distribution boards or motor control centers. The undervoltage release and auxiliary contacts are factory-integrated, reducing field wiring. Phase failure detection is active via the ETU350M trip unit — no separate monitoring module needed. The trip indicator provides local visual status.
