Interrupting capacity is the number that decides whether this breaker clears a fault or welds shut: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. The shunt trip release (STL) fitted as standard means you can remotely trip this breaker from a safety relay, E-stop circuit, or fire alarm panel. No undervoltage release is present, so a loss of control power won't drop the breaker — that's the right choice for critical process loads that must stay online unless commanded off. ## Sourcing and lifecycle — current production, quoted to order The SENTRON 3VA series is Siemens' standard MCCB platform for commercial and industrial power distribution. Spares holding is straightforward: the 400 A rating and 4800 A frame are common enough that a replacement can be sourced without a long lead-time risk, but keeping one in the cabinet for a critical feeder is the prudent move — no spare, no sleep. Maximum power loss is 63.5 W — account for that in your enclosure thermal calculation if the breaker is enclosed with other heat sources.","metaTitle":"Siemens 3VA2440-5HN32-0KA0 SENTRON MCCB, 400 A, 4800 A Frame","metaDescription":"Siemens SENTRON 3VA2440-5HN32-0KA0 molded case circuit breaker. 400 A rated, 4800 A frame, 187 kA at 240 V. 3-pole with shunt trip.
