Siemens SENTRON 3VA2116-5KP32-0JL0 is a 3-pole molded case circuit breaker rated for 160 A continuous current with a maximum interrupting capacity of 187 kA at 240 VAC. Designed for line protection, it includes a shunt trip release and communication function for integration into automated systems.
SCCR Headroom and Coordination
The 187 kA SCCR at 240 V and 121 kA at 415 V give this breaker high fault-clearing capability for main or feeder panels where available fault current is substantial. At 690 V the rating drops to 3.7 kA, so for 690 V applications verify coordination with upstream devices. The 160 A continuous rating holds flat across 40 °C to 70 °C ambient — no derating needed in warm enclosures.
Dimensions are 105 mm wide, 86 mm deep, 181 mm tall — fits standard MCCB panel cutouts. The 3-pole design with line-side and load-side lugs accepts copper or aluminum conductors. Auxiliary switch configuration includes 2 auxiliary switches plus 1 trip alarm and 1 electrical alarm switch (HQ type), providing status feedback for PLC or SCADA. Power loss is 25.5 W maximum at rated load.
