MCCB for line protection with high interrupting capacity
The Siemens SENTRON 3VA2116-5HN32-0HC0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, designed for line protection in distribution panels. Its interrupting capacity reaches 187 kA at 240 V AC and 121 kA at 415 V AC, which means it can safely clear high-fault currents without upstream damage — critical for main breaker or high-fault bus applications where selectivity is needed.
Shunt trip and auxiliary switch complement
This MCCB ships with a shunt trip release (STL) for remote tripping and two HQ auxiliary switches for status feedback — a common specification for emergency-stop circuits or remote monitoring. The shunt trip allows a PLC or safety relay to open the breaker on command, while the auxiliary switches signal the open/closed state back to the control system.
Physical fit and panel integration
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA frame size that mounts on a DIN rail or panel-mount adapter. The 86 mm depth leaves clearance for rear-connected busbars in typical switchgear enclosures.
