Protective Devices
Miniature Circuit Breakers PLS..., PLZ...
• High selectivity between MCB and back-up fuse due to low let-through
energy
• Compatible with standard busbar
• Twin-purpose terminal (lift/open-mouthed) above and below
• Busbar positioning optionally above or below
• Meets the requirements of insulation co-ordination,
distance between contacts ≥ 4 mm, for secure isolation
• Suitable for applications up to 48 V DC (use PLS6-DC for higher DC volt-
ages)
