Product details
The Terasaki S400-NN 381577 is a 400 A, 4-pole moulded-case switch-disconnector on the TemBreak 2 400 A frame, rated AC-23A at up to 690 V AC. With no trip unit it neither opens on overload nor clears a short circuit, so the supply to it needs protection upstream.
Key features
- Front connection with M10 terminal screws; extension bars, cable clamps, rear connection and plug-in versions optional
- Direct opening action and toggle operation; door- or breaker-mounted handles and a motor operator optional
- Takes auxiliary and alarm switches, plus a shunt trip or an under-voltage release
Typical applications
Main switch of a Resilience Standard MCCB panel board fed from a protected way of the upstream LV switchboard. Its fourth pole switches and isolates the neutral with the phases. It also serves as an on-load isolator for sub-mains and plant. The Panel Builder lists it among the incoming devices.
Compliance
Rated to IEC 60947-3 and EN 60947-3 (also AS/NZS 3947-3) according to the series datasheet.
