The Siemens SENTRON 3VA2340-6HL32-0AB0 is a 3-pole molded case circuit breaker rated 400 A continuous at 40 °C, with an interrupting capacity of 242 kA at 240 V — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream. Two HP auxiliary switches are built in for status feedback to the PLC or panel indication.
Ratings that matter for panel fit
At 415 V and 440 V the interrupting rating holds at 187 kA; at 690 V it drops to 7.5 kA — still adequate for most 690 V motor circuits but not for high-fault 690 V mains. The continuous current derates above 55 °C: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, 340 A at 70 °C.
Physical integration
The 110 mm depth leaves room for rear-access wiring in a 300 mm deep cabinet.
