Protective Devices
Miniature Circuit Breakers with Plug-in Terminals PLI
• High selectivity between MCB and back-up fuse due to low let-through
• Plug-in terminals above (at the output side)
• Two terminal points per pole
• Single-wire lines can be connected without tools
• The conductor can be removed from the plug-in terminal and single- or
fine-wire lines can be connected by means of a screwdriver DIN 5264 Type
A and Type B (maximum blade width 3 mm)
• Twin-purpose terminal (lift/open-mouthed) below
• Compatible with standard busbar below
• Meets the requirements of insulation co-ordination,
distance between contacts ≥ 4 mm, for secure isolation
• Suitable for applications up to 48 V DC
