Product details
The Terasaki S800-NF 498008 is a 4-pole, 400 A moulded-case circuit breaker with a thermal-magnetic trip unit, built on the TemBreak 2 800 A frame. Its ultimate breaking capacity is 36 kA at 400/415 V AC, and it is one of the incoming devices offered for 400 A Resilience Plus panel boards.
Key features
- Thermal (overload) and magnetic (short-circuit) protection in one device
- 400 A rated current on the TemBreak 2 800 A frame
- Icu 36 kA at 400/415 V AC
- Front connection
- Takes an interpole barrier, toggle lock, connection bars and terminal covers from the 800 A frame accessory range
Typical applications
Protected incomer for a 400 A Resilience Plus board, installed in the board's separate incomer housing (sold separately). Where the board must carry its own overload and short-circuit protection, this breaker is the alternative to the S800-NN switch-disconnector, which has no trip unit. The fourth pole switches the neutral with the phases. The Panel Builder lists it among the incoming devices for these boards.
Accessories that fit: toggle lock 037306; connection bars 067938 and 067945; terminal covers 045769, 045776, 081040 and 081057; interpole barrier 043338. Interpole barriers and standard terminal covers cannot be fitted together.
