General Information: • Open fuse indication. • Provides motor overload, ground fault and short-circuit protection. • Helps protect motors against burnout from overloads. • Helps protect motors against burnout from single-phasing on three-phase systems. • Simplifies and improves blackout prevention (selective coordination). • 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 overcurrent of overloads and will hold an overload which is five times the amp rating of the fuse for a minimum of eight seconds.
