The Siemens 3VA1140-6GF42-0AA0 is a SENTRON molded case circuit breaker (MCCB) sized for line protection in 4-pole configurations. Rated 40 A continuous with a TM240 thermal-magnetic overcurrent release, it delivers 220 kA interrupting capacity at 240 V — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream. The interrupting curve drops to 154 kA at 415 V and 121 kA at 440 V, then to 17 kA at 500 V and 690 V, so selectivity studies need to check the actual system voltage. No undervoltage release, no ground-fault monitoring, and no communication module onboard — this is a straight line-protection breaker for dedicated feeder circuits.
