Siemens 3VA2116-5JQ32-0CL0 — SENTRON MCCB, 160 A, Line Protection
The Siemens 3VA2116-5JQ32-0CL0 is a SENTRON molded case circuit breaker (MCCB) rated at 160 A continuous, 3-pole, designed for line protection. Its interrupting capacity reaches 187 kA at 240 V and 121 kA at 415 V and 440 V, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V — so at typical 400 V distribution it clears high-fault currents without cascading upstream. The thermal rating holds flat at 160 A from 40 °C through 70 °C, meaning no derating in a warm panel.
Integration — Panel Fit and Auxiliaries
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA footprint that fits existing DIN-rail or panel-mount cutouts for this frame size. The breaker ships with an undervoltage release (UVR) and a complement of auxiliary switches: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch HQ. A communication function is built in, supporting integration with line-monitoring or energy-management systems.
