Product details
The Terasaki S250-SN 930973 is a 250 A, 4-pole moulded-case switch-disconnector on the TemBreak 2 Lite 250 A frame. It switches load current (AC-23A) and isolates the circuit, but it has no thermal or magnetic release, so it gives no overload or short-circuit protection: the supply must be protected upstream.
Key features
- Ue up to 690 V AC or 250 V DC; Icw 3 kA for 0.3 s, Icm 6 kA peak
- Front connection with M8 terminal screws; extension bars, cable clamps and rear connection optional
- Direct opening action and toggle operation; door- or breaker-mounted handles and motor operation optional
Typical applications
Main switch of a Resilience Standard MCCB panel board fed from a protected circuit, such as a fused way in the upstream switchboard. Its fourth pole switches and isolates the neutral with the phases. It also serves as an on-load isolator for sub-mains. In the Panel Builder it can be chosen as the incomer of a complete board.
Compliance
Rated to IEC 60947-3 and EN 60947-3 (also AS/NZS 3947-3), as stated on the series datasheet.
