Description

The Mercury T10A is a 6 x 32mm slow blow glass fuse rated at 10A and 250V, designed for equipment with inductive loads or motors that draw high start-up currents before settling to a lower running current. The time-delay element inside the glass tube allows brief current surges during motor start-up or capacitor charging without blowing, while still providing overcurrent protection once the surge period has passed.

These fuses suit applications such as audio amplifiers, motor-driven appliances, power supplies with large transformers, and lighting control equipment where the initial inrush current can be several times higher than the steady-state running current. The glass body allows visual inspection of the element after a fault to confirm whether the fuse has blown. The 6 x 32mm format is a standard cartridge size compatible with fuse holders commonly found in UK and European equipment.

The T10A rating denotes a 10-amp breaking capacity with a time-delay characteristic, meaning the fuse tolerates short-duration overcurrent conditions without interrupting the circuit. The fuses are manufactured to IEC 60127 standards, ensuring consistent performance and compatibility with equipment specifying IEC-compliant fuses. Each fuse has nickel-plated brass end caps for reliable contact in the fuse holder and corrosion resistance over the service life.

Frequently Asked

What is the difference between slow blow and fast blow fuses?

Slow blow (time-delay) fuses allow brief current surges without blowing, making them suitable for motors and transformers that draw high inrush currents on start-up. Fast blow fuses interrupt the circuit immediately when the rated current is exceeded, providing protection for sensitive electronics that cannot tolerate even short overcurrent conditions.

What voltage rating do these fuses carry?

These fuses are rated at 250V. They can be used in circuits with lower voltages, but should not be installed in equipment operating above 250V.

How do I know if a fuse has blown?

The glass body allows visual inspection. A blown fuse typically shows a broken wire element inside the tube, and the glass may be darkened or blackened from the arc that occurred when the element melted. If the element appears intact and continuous, the fuse is likely still functional.

Are these fuses suitable for automotive use?

No. These are designed for mains-voltage equipment operating at 230V AC. Automotive fuses use different form factors (blade fuses, mini/maxi fuses) and are rated for 12V or 24V DC circuits.
