The Siemens SENTRON 3VA2340-5HL32-0DH0 is a 3-pole molded case circuit breaker rated for 400 A continuous current (at 40 °C through 50 °C) and designed for line protection.
That's a standard SENTRON 3VA2 frame footprint — it bolts into the same mounting holes as other 3VA2 3-pole breakers in the 400 A class. The 110 mm depth leaves room for rear-connected busbars or a cable-entry gland plate in a 600 mm deep enclosure.
Submit an RFQ — the part is sourced to order through independent distribution, and pricing and lead time are confirmed at quote time.
No — the 3VA1020-2ED32-0DD0 is a different frame size (100 A class, different mounting footprint). The 3VA2340-5HL32-0DH0 is a 400 A frame; verify the busbar spacing and enclosure cutout before substitution.
Siemens SENTRON MCCBs typically carry UL 489, IEC 60947-2, and CE marking. RoHS and REACH declarations are available from Siemens documentation portal. The evidence does not list specific certs for this order code — confirm with the supplier at quote time.
