Product details

The Terasaki S250-SJ 930744 is a 160 A, 4-pole MCCB on the TemBreak 2 Lite 250 A frame with an ultimate breaking capacity of 40 kA at 400/415 V AC. Its thermal-magnetic trip unit is adjustable for both overload and short-circuit pick-up.

Key features

  • Rated current In 160 A at 50 °C, with the thermal (overload) pick-up adjustable
  • Adjustable magnetic trip: band of 400-600 % of In at minimum, 1040-1560 % at maximum
  • Front connection with M8 terminal screws; extension bars, cable clamps and rear connection optional

Typical applications

Incoming device for a 400 A Resilience Plus panel board, where it sits in a separate incomer housing (sold separately). The fourth pole switches the neutral with the phases. It also suits feeder protection in switchboards where the fault level is within 40 kA at 415 V. The Panel Builder offers it as an incomer for these boards.

Compliance

Rated to IEC 60947-2 and EN 60947-2 according to the series datasheet (JIS C 8201-2-1 and NEMA AB-1 values also given).
