Heavy-duty, dual element, time-delay cartridge fuse for motor and main panel protection. Helps protect motors against burnout from single-phasing on three-phase systems, and overloads 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 Use general purpose NON fuses for lighting or electric heating circuits. Provides motor overload, ground fault and short-circuit protection Helps protect motors against burnout from overloads and from single phasing on three phase systems Simplifies and improves blackout prevention (selective coordination) Can be applied in circuits subject to temporary motor overloads and surge currents to provide high performance short-circuit and overload protection Protects against low level overcurrent of overloads and will hold on inrush current 5 times greater than the amp rating of fuse for a min of 8 sec
