Overview
The Bussmann KDR 750 MCM CU cable limiter is a non-indicating, current-limiting protective device engineered for 750 kcmil copper cables operating at 600V AC. Manufactured by Eaton Bussmann, this cable limiter provides short-circuit protection and isolates faulted conductors in multi-conductor electrical systems. The KDR series is rated for 200 kAIC (kilo-amperes interrupting capacity), making it suitable for industrial power distribution and service entrance applications.
Key Features
- 200 kAIC interrupting capacity for reliable fault protection
- 600V AC rated for industrial electrical systems
- Tubular end with offset bolted end terminal configuration
- Copper conductor rated for 750 kcmil cable applications
- Non-indicating design—compact, reliable operation
