MCCB for high-fault panels — 160 A frame, 4-pole, TM220
The Siemens 3VA1116-6EE42-0AA0 is a SENTRON 4-pole molded case circuit breaker rated for 160 A continuous at 40 °C, with a TM220 thermal-magnetic release — meaning the thermal pickup and magnetic trip are fixed, not adjustable. It's built for line protection in distribution panels where you need a high interrupting capacity: 220 kA at 240 V AC, 154 kA at 415 V, 75.6 kA at 440 V, and still 17 kA at 500 V and 690 V. That covers most industrial low-voltage bus faults without cascading upstream.
At 55 °C it's 158 A, at 60 °C it's 155 A, at 65 °C it's 153 A, and at 70 °C it's 150 A. Maximum power loss is 38 W.
Front IP40 protection suits panel-mount installations where the breaker face is exposed.
