Breaking capacity is the headline here: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 9 kA at 690 V. The adjustable thermal-magnetic trip range spans 600 A to 4800 A (likely the instantaneous magnetic pickup range; the 400 A continuous frame sets the thermal element). That wide adjustment band lets you coordinate selectively with downstream breakers without swapping the entire unit. The 138 mm width (5.43 in) fits three-pole spacing on a DIN rail. Maximum power dissipation is 63.5 W. In a sealed enclosure, that heat needs to be factored into the thermal budget — at full load it's roughly the same as a small soldering iron running continuously inside the panel. That's enough for remote status indication (open/closed/tripped) without adding external relays. The storage minimum is the more restrictive limit for warehousing — keep it above -40 °C and the molded case stays compliant.","metaTitle":"Siemens 3VA2440-7HL32-0AH0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens 3VA2440-7HL32-0AH0 SENTRON molded case circuit breaker. 400 A continuous, 3-pole, line protection.
