Interrupting capacity hits 330 kA at 240 V AC and still carries 242 kA at 415/440 V — that is serious fault-current headroom for a 400 A frame, meaning it can handle high-available-fault installations without cascading upstream. Depth of 110 mm leaves enough finger clearance behind a gland plate for rear-connected bus bars or cable lugs. The UVR drops the breaker when control voltage falls — common on safety circuits or emergency-stop chains where you want the main breaker to open on loss of control power. The trip alarm switch gives a positive signal that the breaker has opened on fault, not manually. This order code carries a current-production lifecycle status. The basic switch variant is 3VA2440-7HL32-0AA0, which is the core breaker without the auxiliaries — so if you already have that base model in a BOM, the -0BH0 adds the UVR and alarm switch on the same frame.","metaTitle":"Siemens 3VA2440-7HL32-0BH0 SENTRON MCCB, 400 A, 4800 A max,","metaDescription":"Siemens SENTRON 3VA2440-7HL32-0BH0 molded case circuit breaker, 400 A rated, 4800 A max setting, 330 kA at 240 V.
