The Siemens SENTRON 3VA2216-7MN32-0HA0 is a 3-pole molded case circuit breaker (MCCB) in the 3VA2 platform, designed specifically for motor protection. It carries a continuous current rating of 160 A across the full ambient temperature range from 40 °C through 70 °C — no derating needed up to that ceiling, which simplifies panel thermal budgeting when the breaker sits near other heat sources. Breaking capacity is substantial at the lower distribution voltages: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V. The steep drop at 690 V means this frame is optimized for 240–500 V networks — common in North American and European motor control centers — not for 690 V industrial grids where a higher-rated frame would be needed. The breaker includes a shunt trip release (STL) for remote tripping via a control signal — useful in emergency-stop chains or supervisory shutdown circuits. Phase failure detection is built in, which for a motor-protection breaker means it will trip on loss of a phase, preventing single-phasing damage to the motor. No undervoltage release, no auxiliary switch, and no ground-fault monitoring on this variant; those functions would need a different suffix or add-on modules.
Maximum power loss is 19.7 W — modest for a 160 A frame. In a densely packed enclosure, that loss figure helps when calculating internal temperature rise and ventilation requirements. The operating temperature range spans -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Physical footprint: 105 mm wide, 181 mm high, 86 mm deep. Width is the critical dimension for panel layout — a 105 mm wide 3-pole MCCB fits standard distribution panel cutouts and busbar spacing. Depth of 86 mm leaves clearance for rear-mounted busbars and wiring troughs without requiring extra-deep enclosures. The breaker ships as a basic switch (base order code 3VA2216-7MN32-0AA0) with the shunt trip installed. No communication module, no auxiliary switch block — it is a standalone thermal-magnetic or electronic-trip device (designated for motor protection) meant for hardwired control circuits. Trip indicator is not fitted on this variant.
