Product details
Terasaki S400-NE 379604 is a 250 A, 3-pole TemBreak 2 electronic moulded-case circuit breaker on the 400 A frame, rated 50 kA Icu and Ics at 400/415 V AC, with a current setting from 100 A to 250 A. Terasaki lists it as an outgoing device for the Resilience Plus twin 400 AF board.
Key features
- Electronic trip: current setting IR from 0.4 to 1.0 x In in seven steps
- Seven selectable characteristics set the long-time delay, short-time pick-up (2.5, 5 or 10 x IR) and delay (0.1 or 0.2 s)
- Instantaneous trip at 14 x IR, capped at 13 x In
Typical applications
For 250 A ways on the twin 400 AF board, feeding sub-boards or large plant. Against the S250-NE 250 A (331909) it adds a 50 kA service rating, seven characteristics and category B (Icw 5 kA for 0.3 s) for time-graded discrimination. Our Panel Builder adds it to a Resilience Plus layout and 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), interpole barrier 043338, terminal cover 081347, connection bar 010323 and toggle lock 037306. Interpole barriers and standard terminal covers cannot be fitted together.
