Description

The Mercury T6.3A is a 6 x 32mm slow blow fuse rated to 250V, designed to tolerate brief current surges without blowing. The delay-action element allows inrush currents from motors, transformers and capacitive loads to settle before the fuse decides whether to interrupt the circuit, reducing nuisance blowing in equipment with high startup currents.

Designed for audio amplifiers, PA equipment, power supplies and control panels where motor-driven or transformer-fed circuits generate brief current spikes on power-up, the slow blow design gives the fuse a few milliseconds to distinguish between a genuine overcurrent fault and a short-lived inrush. The 6 x 32mm cartridge format fits standard PCB-mount and panel-mount fuse holders used across consumer electronics, professional audio and industrial control equipment.

The glass body allows visual inspection of the fuse element to confirm whether the fuse has blown, while the nickel-plated brass endcaps provide consistent contact in spring-clip fuse holders. IEC compliance ensures the fuse meets international electrical safety standards for use in equipment sold across Europe and the UK.

Frequently Asked

What's the difference between slow blow and fast blow fuses?

Slow blow fuses tolerate brief current surges (typically a few milliseconds) before interrupting the circuit, making them suitable for equipment with high startup currents such as motors and transformers. Fast blow fuses respond immediately to overcurrent and are used where load currents remain steady and any surge indicates a fault.

What voltage rating does this fuse carry?

The T6.3A is rated to 250V. It can be used in lower-voltage circuits (e.g. 12V, 24V, 110V) but should not be used in circuits exceeding 250V.

How many fuses are included?

Check the product Specification or packaging details for the quantity per pack. Mercury fuses are typically sold in packs of 5 or 10.

Is this fuse IEC compliant?

Yes. The fuse meets IEC standards for electrical safety, making it suitable for use in equipment requiring international certification.
