Product details
Terasaki S250-SJ 933561 is a 50 A, 3-pole TemBreak 2 Lite moulded-case circuit breaker on the 250 A frame, with adjustable thermal-magnetic protection and 40 kA Icu at 400/415 V AC. Terasaki lists it as an outgoing device for Resilience Plus 6, 12 and 18 way boards.
Key features
- TemBreak 2 Lite device with adjustable thermal and magnetic trips
- Icu 40 kA, Ics 20 kA at 400/415 V AC
- Suits AC systems to 690 V and DC to 250 V
Typical applications
A 50 A three-phase way for small sub-distribution boards and plant. Note the service rating: Ics is 20 kA at 400/415 V, half the Icu. If the design needs more, the TemBreak 2 S160-NJ 50 A (326851) is rated 36 kA Icu and Ics, and the S160-GJ 50 A (327025) 65 kA Icu. 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).
Lite accessories that fit: auxiliary switch 002489, alarm switch 002557, a shunt trip or an under-voltage release (one trip-coil pocket, so not both), handle lock 064906, terminal covers 065309, 065316 and 080456, terminal cover lock 065644, cable clamps 062247 and 062254, and interpole barrier 065729.
