MCCB with 160 A frame and 187 kA interrupting rating
The Siemens SENTRON 3VA2116-5JQ32-0HL0 is a 3-pole molded case circuit breaker rated for 160 A continuous current with a breaking capacity of 187 kA at 240 V AC. That interrupting rating drops to 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — so the voltage class of your distribution panel determines which fault current spec governs the application.
The 160 A frame is thermally rated with a current derating curve: it holds 160 A all the way up to 50 °C ambient, then steps down to 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C (–). The maximum power loss is 25.5 W, which adds to the enclosure's thermal load.
Trip unit and auxiliary features
The integrated auxiliary trip accessory is order code 3VA9688-0BL30, and the basic switch version of this breaker is 3VA2116-5JQ32-0AA0 — the -0HL0 suffix adds the communication function and the specific auxiliary contact arrangement.
