Miniature Circuit Breakers 5SY and 5SP
Overview
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. For further information, please refer to the section
"Configuration".
