Overview
Miniature Circuit Breakers 5SY and 5SP
MCBs are used to protect plants in buildings and for industrial applications. The devices can be used as main switches for the disconnection or isolation of plants.
For industrial applications and in plant engineering, miniature circuit breakers can be supplemented with additional components, such as auxiliary switches, fault signal contacts, shunt trips, undervoltage releases, remote controlled mechanisms and RC units.
The devices are approved for worldwide use according to IEC standards for systems up to 250/440 V AC. 60 V DC per pole is permitted in DC systems.
For North America, we also have additional certification to UL 1077 for use as “supplementary protectors” in systems up to 480Y/277 V AC. For use in ship building, the devices have numerous certifications according to shipping classifications BV, DNV, GL and LRS.
