Siemens SENTRON 3VA2116-5HL32-0HL0 — 160 A MCCB, Line Protection
The Siemens SENTRON 3VA2116-5HL32-0HL0 is a 3-pole molded case circuit breaker rated for 160 A continuous current at 40 °C through 70 °C ambient — no derating needed across that full operating range. Breaking capacity runs 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 — the 690 V figure confirms this is a 3-pole breaker on a 4-wire system where the fourth pole is switched but not protected. Designed for line protection (not feeder or motor protection), with a shunt trip release (STL) and a 2+1+1 auxiliary switch configuration: two auxiliary switches, one trip alarm switch, and one electrical alarm switch HQ. Dimensions are 105 mm wide × 181 mm high × 86 mm deep — standard SENTRON 3VA2 frame size, so it drops into existing 3VA2 panel cutouts and busbar arrangements without rework.
