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.","metaTitle":"Siemens 3VA2340-6HL32-0AB0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6HL32-0AB0 molded case circuit breaker, 400 A, 242 kA interrupting at 240 V.
