S280 miniature circuit breakers are claimed to be the only MCBs capable of providing overcurrent protection for equipment and cables up to 100A within a standard width single-pole module.
S280 miniature circuit breakers are claimed to be the only MCBs capable of providing overcurrent protection for equipment and cables up to 100A within a standard width (17.5mm) single-pole module.
The single-pole S280 MCBs, together with double-, triple- and four-pole versions offer the capability to create compact distribution boards for a wide variety of commercial and industrial applications without the requirement for a separate panel board.
They are rated for either 80 or 100A with a breaking capacity of 6kA in accordance to BS EN60898, and are available with tripping characteristics B or C.
The S280 MCBs are ideally suited for installation in ABB's Protecta final distribution boards or can simply be mounted on standard top hat DIN rail.
In common with the other MCBs in ABB's well established S260 and S270 ranges, they can be coupled with the same shared series of auxiliary elements and accessories to provide a variety of functions and configurations.
These typically include: auxiliary contacts, signal contacts, shunt trips and undervoltage releases etc.
