Cooper Bussmann BP/T-6-1/4 T Plug Fuse 6-1/4A Time Delay 250V

Description

Product Overview

The Cooper Bussmann BP/T-6-1/4 T plug fuse is engineered to provide dependable time‑delay protection for a wide range of motor‑driven equipment. Rated at 6‑1/4 amps and designed for a 250‑volt system, this fuse is built to handle the inrush currents that occur when motors start, while still safeguarding downstream components from overloads. Its through‑hole mounting style fits standard Edison‑base sockets, allowing easy replacement without the need for specialized tools. Constructed from high‑impact plastic, the fuse body resists cracking and deformation under harsh industrial conditions. The product meets CSA, UL, and IEC certification requirements, confirming its suitability for commercial and industrial applications where safety and reliability are paramount. Dimensions of 4.75 × 2.75 × 1.25 inches make it compact enough for tight panel spaces, and the lightweight design (1.6 oz) reduces overall system weight. The dual‑element construction provides an exclusive safety mechanism that interrupts the circuit only after a predetermined delay, preventing nuisance trips during normal motor start‑up while still protecting against sustained overloads.

Usage

This plug fuse is ideally suited for protecting critical motor circuits in environments where equipment cycles on and off frequently, such as HVAC compressors, pumps, conveyors, and industrial fans. Its time‑delay characteristic allows the initial surge of current that motors draw at start‑up to pass without tripping, which is essential for maintaining operational continuity in automated production lines. The fuse can also be employed in commercial lighting fixtures that use electronic ballasts, where brief current spikes are common. Because it conforms to CSA, UL, and IEC standards, the BP/T-6-1/4 is accepted in North American and international installations, making it a versatile choice for contractors, facility managers, and maintenance technicians. The plastic housing ensures resistance to moisture and dust, allowing use in outdoor or semi‑outdoor panels, while the through‑hole design simplifies retrofitting into existing equipment without extensive rewiring. Whether you are upgrading an older system or specifying new equipment, this fuse provides a reliable safeguard against overloads and short‑circuit conditions.

FAQ

What does a time‑delay (T) plug fuse do?

A time‑delay plug fuse is designed to tolerate the brief surge of current that occurs when motors or other inductive loads start. Unlike fast‑acting fuses, it allows this temporary overload to pass without blowing, then trips if the overload persists, protecting the circuit from damage.

Can I use this fuse in a 120 V system?

While the fuse is rated for up to 250 V, it can be safely used in lower voltage systems such as 120 V, provided the current rating (6‑1/4 A) matches the circuit requirements. Always verify that the fuse’s voltage and current ratings are appropriate for your specific application.

Is the plastic housing suitable for outdoor installations?

Yes, the high‑impact plastic housing offers resistance to moisture and dust, making the fuse suitable for outdoor or semi‑outdoor panels. However, it should still be protected from direct exposure to extreme weather conditions and installed in a sealed enclosure when possible.

How do I replace a faulty fuse safely?

First, disconnect power to the circuit and verify that the voltage is zero using a multimeter. Then, remove the old fuse by pulling it straight out of the Edison‑base socket. Insert the new Cooper Bussmann BP/T-6-1/4 T plug fuse, ensuring it seats firmly. Restore power and test the equipment to confirm proper operation.

What warranty does this fuse come with?

The fuse is covered by a standard manufacturer warranty that protects against defects in materials and workmanship. For detailed warranty terms, refer to the product packaging or contact the seller’s customer service department.
