Product details
The Terasaki S800-NE 812262 is a 630 A, 3-pole electronic MCCB on the TemBreak 2 800 A frame, rated 50 kA Icu and Ics at 400/415 V AC. As a category B device with Icw 10 kA for 0.3 s, its short-time delay can be used to discriminate with the outgoing devices below it.
Key features
- Long-time pick-up IR adjustable in seven steps, 0.4 to 1.0 x In (252 A to 630 A)
- Seven selectable characteristics set the long-time delay, short-time pick-up (2.5, 5 or 10 x IR) and short-time delay (0.1 or 0.2 s)
- Instantaneous trip at 14 x IR, capped at 12 x In
- Front connection; extension bars, cable clamps (630 A only), rear connection and plug-in optional
Typical applications
Incoming device for an 800 A Resilience Plus panel board, fitted in the board's separate incomer housing (sold separately), where adjustable electronic settings help grade the incomer between the upstream protection and the outgoing MCCBs. As a 3-pole incomer it needs the board's matching neutral link, ordered separately. Use the Panel Builder to place it at the head of a complete board.
Compliance
On the S800-NE datasheet the electrical characteristics are stated to IEC 60947-2 and EN 60947-2, alongside 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.
