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. It ships with an undervoltage release (UVR) and a complement of 2 auxiliary switches plus 1 trip alarm switch (HQ design), and includes onboard communication — so it's ready for remote monitoring and emergency trip in a safety circuit.
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. Operating range is -25 °C to 70 °C; storage from -40 °C to 80 °C. 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.
