Product details
Terasaki S250-NE 331800 is a 125 A, 3-pole TemBreak 2 electronic moulded-case circuit breaker on the 250 A frame, with 36 kA Icu and Ics at 400/415 V AC and a current setting from 50 A to 125 A. It is one of Terasaki's outgoing devices 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
Choose electronic over the thermal-magnetic S160-NJ 125 A (326882) when the setting must match a cable or load closely (100 A at 0.8 x In, say) or must grade with downstream breakers. Typical duties: sub-mains and plant feeders. The S250-GE 125 A (332104) is the 65 kA version. Plan the whole board in our Panel Builder, with a drawing 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), terminal covers 080517 and 080654, cable clamps 081354 and 080586, and toggle lock 037016.
