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.
