The Siemens SENTRON 3VA2116-5HL32-0KH0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity reaches 187 kA at 240 V AC and 121 kA at 415 V / 440 V, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V.
Line protection design with shunt trip
This variant is configured for line protection (not feeder or motor protection), meaning the thermal-magnetic trip curve is set for cable and busbar protection in distribution panels. The shunt trip allows remote tripping via a control voltage — useful for emergency-off circuits or interlocking with a fire-alarm panel. No undervoltage release is fitted on this order code. There is no ground-fault monitoring module and no communication function; this is a standalone breaker for hardwired distribution.
The 86 mm depth includes the arc-chamber housing and rear terminals; verify clearance to the enclosure door or deadfront.
