The Siemens SENTRON 3VA2110-7MS36-0KA0 is a 3-pole molded case circuit breaker rated 100 A continuous with a maximum rating of 1500 A and an interrupting capacity of 330 kA at 240 V — that SCCR headroom covers most industrial distribution transformers and motor branch circuits without needing a current-limiting upstream device.
Interrupting capacity across voltage levels
At 415 V and 440 V this breaker holds 242 kA, dropping to 187 kA at 500 V and to 3.7 kA at 690 V. The steep fall at 690 V means it is not a primary choice for 690 V distribution — that 3.7 kA figure is adequate only for low-fault-current sub-circuits. At the common 240 V and 400 V class levels, the 330 kA and 242 kA ratings give selectivity headroom for a main breaker feeding downstream feeder breakers.
No DIN-rail mount — this is a bolt-on or plug-in base frame. The shunt trip wiring needs a separate control voltage source; verify the trip coil rating against the panel's 24 VDC or 110 VAC control supply before terminating. The 10 W maximum power loss means ventilation in a sealed enclosure is not critical, but keep it away from heat-sensitive components on the same sub-panel.
Temperature derating and storage range
Operating minimum is -25 °C, which covers cold-start conditions in outdoor enclosures in most climates.
