RPI RPF059 Fuse (1/4A, 250V) - 1/4 X 1-1/4 - Time Delay

Time delay (or slow-blow) fuses are essential for preventing nuisance blowing. They allow brief, harmless surges in current to pass through without interrupting power, only tripping when a sustained overcurrent is detected. This makes them ideal for equipment that might have minor power spikes during startup.

Yes, the RPF059 fuse is a direct component included within the RPI Fuse Kit (RPK411). If you are restocking or replacing components for that specific kit, this is the exact match you need.

Yes, the glass casing is a standard for visual inspection, allowing you to quickly determine if the internal filament has blown without needing a multimeter. It provides a durable, industry-standard housing for the fuse element.

This fuse features the industry-standard physical dimensions of 1/4 inch diameter by 1-1/4 inch length. This common size is designed to fit a wide range of electrical holders found in general shop equipment.

Absolutely. This fuse is specifically rated and tested for 250V applications. It is engineered to provide precise circuit protection up to that voltage threshold, ensuring safety for your electrical equipment.

Each order includes a retail package containing five (5) individual fuses. This is ideal for shop maintenance, allowing you to keep spares on hand for future replacements.

Yes, RPI parts are supplied as factory-new components. Choosing these replacements ensures that the electrical specifications—such as the 1/4 Ampere rating—meet the necessary safety standards for your equipment.

Yes, this fuse is specifically designed for use in General Shop Aids. It is a reliable electrical component engineered for integration into systems that require accurate, controlled overcurrent protection.

The time-delay design is the key. It offers protection by remaining stable during momentary “inrush” current spikes—which are common when starting devices—while acting swiftly to protect the circuit during dangerous, sustained electrical overloads.

Yes, the 1/4A (0.25 Amp) rating provides the exact sensitivity required for low-current circuits. Using a correctly rated fuse is critical for preventing damage to sensitive electronic components within your hardware.
