Plan the load accordingly. ## Interrupting capacity by voltage The breaker's short-circuit rating varies sharply with system voltage. At 240 V it handles 187 kA; at 415 V and 440 V it's 121 kA; at 500 V it drops to 75.6 kA; at 690 V it's 7.5 kA. For a 400 V distribution board with a high available fault current (over 100 kA), this breaker still holds — but at 690 V it's only suited for low-fault branches. Verify the point-of-installation SCCR against the voltage-specific value. ## Built-in auxiliary and shunt trip That means remote tripping and status feedback are covered without adding external accessories. The 3-pole frame fits standard SENTRON mounting patterns. The breaker includes a trip indicator and voltage trigger for downstream alarm annunciation.","metaTitle":"Siemens 3VA2340-5HL32-0KH0 SENTRON MCCB, 400A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2340-5HL32-0KH0 molded case circuit breaker. 400A continuous, 3-pole, interrupting capacity 187kA at 240V.
