Circuit breaker guards industrial
applications
New commercial and industrial circuit breakers have current ratings of up to 125A and rated voltages of up to 690V.
ABB has expanded its miniature circuit breaker range with a new high-performance series aimed at industrial and commercial applications Replacing the S500 series, the S800 series offers two levels of breaking capacities depending upon the application requirements

The S800S is aimed at the industrial sector and provides breaking capacities up to 50kA, while the S800N is suitable for commercial applications and offers breaking capacities up to 36kA.
Both ranges have current ratings available up to 125A and rated voltages of up to 690V.
The S800S range bridges the gap between standard MCBs that typically have 10-15kA breaking capacity and maximum currents of 63A, and physically larger moulded case circuit breakers (MCCBs), typically used in industrial applications.
Aimed at OEMs and the industrial sector, the S800S series can be used to provide protection in industrial environments.
It increases the amount of space available in switchboards and other enclosures by offering the same levels of performance as MCCBs but in reduced physical dimensions.
The S800S range is ideal for traction applications onboard rolling stock and trackside, marine installations, plus industrial environments such as petrochemical and steel plants.
Tripping curves available are B, C, D plus K, and Universal Current versions offer 250V DC ratings per pole.
The S800N series has been developed for commercial building applications such as shopping centres, airports, hospitals and office blocks.
Tripping curves available are B, C and D.
Both the S800S and S800N ranges are available in 1,2, 3 or 4-pole versions.
All versions are designed to be fitted onto standard DIN rail and are complemented with a full range of customer fitted accessories such as auxiliary contacts, shunt trips, under voltage trips, rotary drive mechanisms and RCD blocks up to 63A rating.
Both the S800S series and S800N series MCBs are available through ABB's distribution network.
