160 A MCCB with shunt trip and auxiliary switch block
The Siemens 3VA2116-5HL36-0KL0 is a SENTRON molded case circuit breaker rated for 160 A continuous current across the full ambient range from -25 °C to 70 °C, with no derating needed up to 70 °C. The 3-pole design is configured for line protection, so the internal trip curve is set for feeder or main breaker duty rather than motor or generator protection.
The shunt trip allows a remote pushbutton or safety relay to open the breaker, which is common in emergency-stop circuits or undervoltage protection schemes where a separate undervoltage release is not fitted (this unit has no undervoltage release).
The 105 mm width fits existing cutouts for a 3-pole 160 A frame.
The interrupting rating drops significantly as system voltage rises: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. For 400 V class systems (415/440 V), the 121 kA rating covers most high-fault installations.
