MCCB with shunt trip — 160 A, 3-pole, high interrupting capacity
The Siemens SENTRON 3VA2116-6HN32-0HA0 is a 3-pole molded case circuit breaker rated 160 A continuous current, designed for line protection in distribution panels. Interrupting capacity reaches 242 kA at 240 V and 187 kA at 415 V, dropping to 3.7 kA at 690 V — the high 240 V figure suits low-voltage main or feeder duty where fault current can exceed 100 kA. The built-in shunt trip (STL) release allows remote tripping via a control signal, which is useful for emergency-stop or supervisory shutdown circuits.
Sizing and thermal performance
Rated 160 A continuously from 40 °C up to 70 °C ambient — no derating needed across the full operating temperature range, which simplifies panel layout when the breaker is near other heat sources. Power loss at full load is 25.5 W maximum. Insulation voltage rated 800 V.
Dimensions and panel fit
Measures 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint for 160 A frame size. The 86 mm depth is the dimension from mounting surface to the furthest projection, relevant when clearing a gland plate or rear-panel wiring trough.
