160 A MCCB for line protection — flat derating to 70 °C
The Siemens SENTRON 3VA2116-6HL32-0AB0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, designed specifically for line protection — meaning it guards the feeder or distribution bus against overloads and short circuits, not a specific motor or load branch. Its continuous current rating holds flat at 160 A from 40 °C all the way up to 70 °C ambient, so no derating is needed in a warm enclosure — a practical advantage when the breaker sits near other heat sources on the DIN rail. Breaking capacity ranges from 242 kA at 240 V down to 3.7 kA at 690 V; at the common 415 V and 440 V levels it delivers 187 kA, which covers most industrial distribution panels with high fault current. Maximum power loss is 25.5 W, which factors into enclosure thermal budgeting when grouping multiple breakers.
Footprint and panel integration
Dimensions are 86 mm deep, 105 mm wide, and 181 mm tall — a standard 3-pole MCCB footprint that fits existing SENTRON mounting bases and busbar systems without panel rework. Operating temperature range is -25 °C to 70 °C; storage range extends from -40 °C to 80 °C, so the breaker handles cold warehouse storage and warm panel operation without issue.
