Cooper Bussmann FRS-R Time Delay Fuses
Dual-element, Time Delay Fuses Range from 10 to 400 Amps
CB-FRS-R-3
What's special about these fuses?
- Provides motor overload, ground fault and short-circuit protection so that your devices are protected from potentially irreparable damage
- Sturdy units will hold an overload up to five times greater than its ampere rating for a minimum of ten seconds giving you peace of mind and security
- Protect your costly and valuable motors against burnout from single phasing on three phase systems

The versatility of these fuses make them ideal for use in circuits that are subject to surge currents such as those caused by motors, transformers and other inductive components.
- Compact size provides an overall cost savings because you can use smaller and less expensive switches, panels and fuses
- An excellent and easy to use tool avoids blackouts caused by circuit overload
- The overload element of the fuse provides protection against low level currents
- Time delay feature allows you to use lesser fuse ampere ratings that cost less than non-time-delay fuses for an overall labor savings
