Narrow Palm Circuit Breaker Copper Lug suits to 120mm² cable, 8mm stud CALCB120-8 NPL120-8

Narrow Palm Circuit Breaker Copper Lug suits to 120mm² cable, 8mm stud CALCB120-8 NPL120-8

Circuit Breaker Lugs are specially designed for terminating large cables to circuit breakers. These lugs address the challenge of reduced flashover distances and narrower connecting tunnels in breakers, which make fitting conventional lugs in breakers difficult due to their wide palms.

Key Features:

• Same barrel dimensions as the standard range: Normal crimping rules apply, using the correct die for the cable size.
• Unique bell mouth design: Ideal for switchboard builders using flexible cables, as it simplifies the insertion of fine stranded conductors.
• High conductivity copper: Made from 99.9%+ cu, providing the best possible electrical properties.
