Product details
The Terasaki S800-NJ 812163 is a 630 A, 4-pole thermal-magnetic MCCB on the TemBreak 2 800 A frame, rated 50 kA for both Icu and Ics at 400/415 V AC, with adjustable thermal and magnetic trips.
Key features
- Rated current In 630 A at 50 °C; the series also includes 800 A
- Icu = Ics = 50 kA at 400/415 V AC and at 440 V AC
- Magnetic trip adjustable from LO to HI; utilisation category A
- Front connection; extension bars, cable clamps (630 A only), rear connection and plug-in optional
Typical applications
Protected incomer for an 800 A Resilience Plus panel board, fitted in the board's separate incomer housing (sold separately). The fourth pole switches the neutral with the phases. It also suits main and sub-main protection in switchboards with fault levels up to 50 kA at 415 V; at 690 V it is rated 20 kA and must not be used on IT systems at that voltage. Use the Panel Builder to place it at the head of a complete board.
Compliance
The S800-NJ datasheet sets out the electrical characteristics to IEC 60947-2 and EN 60947-2, and also lists JIS C 8201-2-1, AS/NZS 3947-2 and NEMA AB-1 values.
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.
