General Information:
• Provides motor overload, ground fault and short-circuit
• The time-delay feature makes it possible to use fuse amp
• Provides a good degree of short-circuit protection (greater
• Gives motor running back-up protection to motors without
• Helps protect motors against burnout from overloads and
• Simplifies and improves blackout prevention (selective
• Dual-element fuses can be applied in circuits subject to

such as those caused by motors, transformers and other
inductive components, these fuses can be sized close to
full-load amps to give maximum overcurrent protection.
