Product details
The Terasaki S1250-NN 106125 is an 800 A, 3-pole switch-disconnector on the TemBreak 2 1250 A frame. It switches and isolates under load (AC-23A) and withstands 15 kA for 0.3 s, but it has no overcurrent release, so overload and short-circuit protection for the incoming cable must sit upstream.
Key features
- 800 A rating on the 1250 A frame
- Icw 15 kA for 0.3 s and making capacity Icm 32 kA peak
- Front-connected; the series datasheet shows extension-bar terminals as standard, with rear connection, plug-in and draw-out versions as options
- Direct opening action and toggle operation; door- or breaker-mounted handles and motor operation optional
Typical applications
Isolating incomer for an 800 A Resilience Plus panel board, mounted in the board's separate incomer housing (sold separately) and fed from a protected way in the main switchboard. As a 3-pole incomer it needs the board's matching neutral link, ordered separately. The Panel Builder includes it among the 800 A incoming devices.
Compliance
Switch-disconnector ratings are stated to IEC 60947-3 and EN 60947-3 on the S1250-NN datasheet, which also refers to AS/NZS 3947-3.
Accessories that fit: toggle lock 035326; terminal covers 081088 and 081095; interpole barrier 043338. Interpole barriers and standard terminal covers cannot be fitted together.
