The Siemens SENTRON 3VA1063-2ED36-0BF0 is a 3-pole molded case circuit breaker rated for 16 A continuous current at up to 55 °C ambient, with a TM220 thermal-magnetic overcurrent release. Its interrupting capacity hits 187 kA at 240 V AC, 121 kA at 415 V, 76 kA at 440 V, and 17 kA at 500 V or 690 V — which means it handles high-fault utility feeds without cascading upstream. The TM220 release is fixed, not adjustable, so the trip curve is set at the factory; verify coordination with downstream devices before panel build. No communication function or ground fault monitoring is built in.
The IP40 front means it's rated for finger-safe touch protection in a closed enclosure.
