- True dual element construction allows sizing of 125% FLA for motor backup protection
- Superior overload and cycling capabilities
- Current limiting provides component short circuit protection
- Provides motor overload, ground fault and short circuit protection
- Helps protect motors against burnout from 1-phasing on 3 ph systems
- The time delay characteristics of these fuses typically allows them to be sized closer to the running ampacity of inductive loads to reduce cost and provide improved over current protection
- These fuses will override normal equipment current surges to reduce unnecessary fuse openings
- Dual element fuses can be applied in circuits subject to temporary motor overloads and surge currents to provide both high performance short circuit and overload protection
- The overload element provides protection against low level over current of overloads and will hold an overload which is five times greater than the ampere rating of the fuse for a minimum of 10 s
- 8 s minimum at 500% of ampere rating response time
