Features & Benefits

• Dual-Element, Time-Delay Construction: Provides protection against both short circuits and overloads, withstanding temporary inrush currents without blowing.

• Current-Limiting: Reduces the amount of energy let through during a fault, minimizing potential damage to downstream components.

• High Interrupting Rating: Ensures safe operation even in high-fault conditions, with a 200 kA interrupting rating at 250 V AC.

• Compact Design: Standard size compatible with most Class RK5 fuse holders.

• Non-Indicating: Suitable for applications where visual indication of a blown fuse is not required.

Applications

• Motor Protection: Ideal for protecting motors from overloads and short circuits in industrial and commercial settings.

• Combination Starters: Used in combination motor starters to safeguard against electrical faults.

• Machinery Disconnects: Provides overcurrent protection in machinery disconnects.

• Motor Control Centers: Ensures reliable protection in motor control centers.

• Power Panelboards: Suitable for use in power panelboards requiring Class RK5 fuses.
