Product details
The Terasaki E250-SJ 930522 is a 250 A, 3-pole thermal-magnetic MCCB on the TemBreak 2 Lite 250 A frame, breaking 25 kA (Icu) at 400/415 V AC. Both trips are adjustable, so it can be set to the incoming cable and graded with the outgoing ways.
Key features
- Rated current In 250 A at 50 °C, with an adjustable thermal (overload) setting
- 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
Protected incomer for a Resilience Standard MCCB panel board. As a 3-pole incomer it needs the board's matching neutral link, ordered separately. It also suits feeder protection in switchboards where the prospective fault current is within 25 kA at 415 V. Choose it as the incomer in the Panel Builder to see the complete board.
Compliance
Rated to IEC 60947-2 and EN 60947-2 per the series datasheet (JIS C 8201-2-1 and NEMA AB-1 values also given).
