The Siemens SENTRON 3VA2116-5JQ32-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 160 A across the full ambient range from 40 °C to 70 °C with no derating needed. It breaks up to 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — giving you selectivity headroom across common distribution voltages without oversizing the frame. The adjustable overcurrent trip range spans 240 A to 1 600 A, with a 32 A initial value and 160 A full-scale setting, so it can be tuned to protect a transformer, feeder, or busway rather than a single load.
At 105 mm wide, 181 mm tall, and 86 mm deep, it fits the standard SENTRON 3VA panel footprint — same bus-bar spacing and mounting hole pattern as the rest of the 3VA family. The 28 W maximum power loss means you can pack it into a moderate-density enclosure without forced cooling, but keep an eye on the internal ambient if you're stacking breakers. That's enough for unheated electrical rooms or outdoor enclosures in temperate climates, but if the panel sees sustained below-freezing startup, the UVR coil must be verified to pull in at the available voltage.
