For a panel running warm near the top of a switchboard, this thermal curve tells you whether the breaker stays within its rated ampacity without a larger frame. Breaking capacity steps down with voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. The 110 mm depth leaves clearance for rear-connected busbars or cable ladders behind the breaker. ## Built-in accessories and wiring The basic switch is order code 3VA2340-7HL32-0AA0, meaning the accessory set is factory-integrated rather than field-added. A trip indicator is present for visual fault confirmation. No ground-fault monitoring or communication module is included on this variant.","metaTitle":"Siemens 3VA2340-7HL32-0CH0 SENTRON MCCB, 400 A, 3-Pole, 330","metaDescription":"Siemens SENTRON 3VA2340-7HL32-0CH0 molded case circuit breaker, 400 A continuous, 3-pole, 330 kA breaking capacity at 240 V.
