protect / Miniature circuit-breaker (MCB)

Circuit-breakers, D-characteristic, 0.3 A/230 V, 400 V AC, 10 kA, for industrial facilities

Miniature circuit-breakers (MCBs) of type DLS 6 are predominately used for overcurrent protection of cables and lines as per VDE 0100-430 and protection against electrical shock as per VDE 0100-410.
Devices of the i design are fitted with a peculiar high rated switching capacity of 10 kA for industrial applications and provide screw terminals with top and bottom strain-relief clamps.
  special quick fastening for removal of multiple miniature circuit-breakers from the bottom or top interconnection
 large, folding label window for a secure hold and protection of the label
 use of conventional wiring rails
 ON/OFF switch position indicator on the switch toggle
 accessories retro-fittable on the right
 labelling software free of charge
