Recommended for AC power distribution system mains, feeders and branch circuits having inductive loads motors, transformers or non-inductive loads lighting, heating, typically allows them to be sized closer to the running ampacity of inductive loads to reduce cost and provide improved overcurrent protection, override normal equipment current surges to reduce unnecessary fuse openings.

Bussmann Time Delay Fuse, Series: ECNR Series, 250 VAC/125 VDC, 60 A, Class: RK5, 200 kA Interrupt, 10 s Response, Dual, Ferrule Terminal, 3 in Length, 0.81 in Dia

• True dual-element construction allows sizing of 125% A full load for motor backup protection
• Superior overload and cycling capabilities
• Provides motor overload, ground fault and short circuit protection
• Helps to protect motors against burnout from overloads and also from one-phasing on three-phase systems
• Current limiting provides component short circuit protection
• Simplifies and improves blackout prevention
• 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 sec
