Product details
Terasaki S160-NJ 326837 is a 20 A, 3-pole TemBreak 2 moulded-case circuit breaker with adjustable thermal-magnetic protection, rated 30 kA Icu at 400/415 V AC. It is the smallest S160-NJ rating, listed by Terasaki as an outgoing device for Resilience Plus 6, 12 and 18 way boards.
Key features
- Thermal (overload) and magnetic (short-circuit) trips, both adjustable
- Icu 30 kA, Ics 25 kA at 400/415 V AC
- Suits AC systems to 690 V and DC to 250 V
- Compact body: 105 mm wide, 68 mm deep, 1.5 kg
Typical applications
Small three-phase ways: a local distribution board, a fan, pump or heater circuit, or light plant. The 20 A and 32 A S160-NJ are rated 30 kA Icu and 25 kA Ics at 400/415 V; at higher fault levels, the electronic S250-NE 40 A (331701, 36 kA) or S250-GE 40 A (332005, 65 kA) can be set to 20 A (0.5 x In). 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), and toggle lock 037016.
