400 A frame with 200 kA interrupting capacity
The Siemens 3VA2340-0KP42-0AA0 is a 4-pole IEC molded case circuit breaker in the 3VA2 family, built on a 400 A frame with an interrupting capacity of 200 kA at 415 V (breaking capacity class E).
ETU850 LSI protection profile
Fitted with an ETU850 electronic trip unit configured for LSI protection: long-time pickup Ir adjustable 160 A to 400 A, short-time pickup Isd 0.6 to 10× In, and instantaneous pickup Ii 1.5 to 12× In. Neutral conductor protection is adjustable (OFF, up to 100%). This makes it suitable for selective coordination downstream of a main breaker — the adjustable time delays let you stage tripping so a feeder fault clears before the main trips.
Compliance and substance declarations
RoHS compliant since 01-10-19. Export control classification: AL N / ECCN 9N9999. No UL or CSA listing appears in the record — this is an IEC-rated device for markets following IEC 60947-2.
Packaging and handling
Packaged singly (packaging quantity 1). Shipping dimensions 265 × 165 × 170 mm. The 400 A frame size is substantial — expect panel cutout and bus bar planning accordingly, not a DIN-rail clip-in.
