Product details

Terasaki S250-GJ 312236 is a 250 A, 3-pole TemBreak 2 moulded-case circuit breaker, the top rating of the 250 A frame, rated 65 kA Icu and 36 kA Ics at 400/415 V AC, with adjustable thermal and magnetic trips. It is one of Terasaki's outgoing devices for Resilience Plus 6, 12 and 18 way boards.

Key features

  • Higher-breaking version of the S250-NJ: 65 kA Icu at 400/415 V AC against 36 kA
  • Ics 36 kA at 400/415 V AC, the same as the NJ
  • Thermal and magnetic trips, both adjustable
  • Suits AC systems to 690 V and DC to 250 V

Typical applications

Main feeders of up to 250 A to sub-boards, motor control centres or large plant where the fault level is above the 36 kA of the S250-NJ 250 A (312038). For electronic protection at the same fault level, the S250-GE 250 A (332203) is the alternative. Our Panel Builder builds the board around it, with a parts list.

Compliance

Electrical characteristics to IEC 60947-2 and EN 60947-2 (Terasaki datasheet).

Accessories that fit: auxiliary switch 000348, alarm switch 000744, a shunt trip or an under-voltage release (one trip-coil pocket, so not both), terminal cover 080517, cable clamps 081354 and 080586, and toggle lock 037016.
