The Siemens SENTRON 3VA2216-5MN32-0DH0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 160 A across the full ambient temperature range from 40 °C through 70 °C — no derating needed up to that ceiling. The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, and still delivers 75.6 kA at 500 V, so it handles high-fault utility feeds and large motor branch circuits.
The 3VA2216-5MN32-0DH0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA frame size that fits the typical DIN-rail or backplate layout in a motor control center. The 3-pole footprint matches the same cutout as other 160 A SENTRON breakers, so swapping a different 3VA unit into an existing panel is straightforward. The undervoltage release (UVR) is factory-fitted; verify control voltage matches the coil rating before energizing.
The 160 A continuous rating at 70 °C is unusual — most MCCBs derate above 40 °C, but this one holds full current all the way up. The undervoltage release (UVR) means the breaker opens automatically when control power drops below the dropout threshold, a common requirement for safety circuits and emergency-stop chains. The auxiliary switches (2 form-C + 1 trip alarm) feed status back to the controller without needing a separate contactor block.
