Product details
The Terasaki S250-SJ 930706 is a 250 A, 3-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 250 A at 50 °C, with the thermal (overload) pick-up adjustable
- Adjustable magnetic trip: band of 400-600 % of In at minimum, 880-1320 % 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 Panel Builder offers the 3-pole version as an incomer or as an outgoing device. As a 3-pole incomer it needs the board's matching neutral link, ordered separately. It also suits feeder protection in switchboards where the fault level is within 40 kA at 415 V.
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).
