What this MCCB carries — and what it means on your line
The Siemens SENTRON 3VA2116-6HL32-0JH0 is a 3-pole molded case circuit breaker rated for 160 A continuous current at 40 °C through 70 °C — no derating needed across that span, which simplifies panel sizing in warm enclosures or near other heat sources. Breaking capacity hits 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 — so for most low-voltage distribution (240–500 V) it handles high-fault scenarios without cascading upstream. Designed for line protection (not motor or generator protection), it ships with a shunt trip release and two auxiliary switches plus one trip alarm switch — enough for remote status and emergency trip integration in a standard panel.
Mounting and panel fit
Dimensions: 181 mm high, 105 mm wide, 86 mm deep. That 105 mm width for a 3-pole MCCB is standard — drops into most DIN-rail or bolt-on panel layouts without re-drilling the gland plate. Operating range -25 °C to 70 °C; storage from -40 °C to 80 °C. The thermal curve is flat on current — 160 A holds at every ambient up to 70 °C — so no extra headroom needed for elevated cabinet temps.
