Monitoring Devices
Miniature circuit breakers are used to protect plants in buildings and infrastructures
for industrial applications. The devices can be used as main control switches for disconnecting or isolating plants.
Additional components offer
increased flexibility
Additional components, such as auxiliary
switches, fault signal contacts, shunt
releases, undervoltage releases, remote
controlled mechanisms and RC units
enhance the miniature circuit breaker's
overall functionality.
Quick and safe assembly
Integrated movable terminal covers located
at the cable entries ensure the terminals
are fully insulated when the screws are
tightened. Manual quick-assembly systems
guarantee convenient time-saving assembly without requiring any tools.
Answers for infrastructure.
