SENTRON 3VA2116-5HN42-0HC0 — 1600 A MCCB for Line Protection
The Siemens 3VA2116-5HN42-0HC0 is a SENTRON molded case circuit breaker (MCCB) rated for 1600 A continuous current, designed for line protection in distribution panels. It carries 187 kA interrupting capacity 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 SCCR curve drops sharply above 500 V, so verify coordination at the system voltage. This 4-pole unit includes a shunt trip (STL) auxiliary release and two HQ auxiliary switches, but no undervoltage release, ground-fault monitoring, or communication function. Rated current holds flat at 160 A from 40 °C through 70 °C ambient — no derating needed across the typical panel temperature range. Maximum power loss is 25.5 W. Operating temperature spans -25 °C to 70 °C; storage range is -40 °C to 80 °C. Dimensions are 181 mm height, 140 mm width, 86 mm depth.
Integration & Panel Fit
Mounts in a standard switchgear enclosure or MCC bucket. The 140 mm width and 86 mm depth fit common distribution panel cutouts. Auxiliary contacts and shunt trip come pre-installed — no field-addon kit needed for the basic release functions. No communication module on board; this is a standalone line-protection breaker, not a power-monitoring device.
