The Siemens SENTRON 3VA2340-6HL32-0AG0 is a 3-pole molded case circuit breaker rated for 400 A continuous current (Iu) across the 40 °C to 50 °C ambient range, derating to 340 A at 70 °C.
Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard SENTRON 3VA frame size for this 400 A class. No DIN-rail clip; this bolts directly to a mounting plate via the four corner slots.
Mechanical endurance is rated at 15,000 cycles — typical for a 400 A frame in distribution duty, not for frequent switching. The SENTRON series carries IEC/UL certifications; compliance documentation (RoHS, REACH, CE, UKCA) is part of the standard delivery package.
