Product details
Terasaki S250-NE 337802 is a 160 A, 3-pole TemBreak 2 electronic moulded-case circuit breaker on the 250 A frame: 36 kA Icu and Ics at 400/415 V AC, current setting from 64 A to 160 A. Terasaki lists it as an outgoing device for Resilience Plus 6, 12 and 18 way boards.
Key features
- Electronic trip: current setting IR from 0.4 to 1.0 x In in seven steps
- Five 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
- Icu and Ics both 36 kA at 400/415 V AC
Typical applications
Suited to 160 A sub-mains and plant rooms that need a set pick-up (80 A at 0.5 x In, 128 A at 0.8 x In) and short-time settings for discrimination. At 103 mm it is deeper than the 68 mm thermal-magnetic S160-NJ 160 A (326899). The S250-GE 160 A (337925) is the 65 kA version. The Panel Builder on this site draws the board and lists the parts.
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), terminal covers 080517 and 080654, cable clamps 081354 and 080586, and toggle lock 037016.
