The Siemens SENTRON 3VA2116-6HL32-0JC0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, designed for line protection in distribution panels and motor control centers. Its breaking capacity scales with system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure tells you this breaker is sized for low-voltage distribution, not 690 V motor circuits where fault current is lower. The breaker carries a shunt trip release (STL) and two HQ auxiliary switches, so it can be wired into a safety circuit or remote-trip scheme without an add-on module.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Rated for continuous operation from -25 °C to 70 °C ambient; storage range -40 °C to 80 °C. Power loss at full load is 25.5 W — factor that into enclosure thermal calculations.
