Description

The Mercury T1A is a 6 x 32mm slow blow fuse rated at 1A and 250V, designed to tolerate brief inrush currents before breaking the circuit. The time-delay characteristic allows short bursts of current that occur when motors, transformers, amplifiers and LED power supplies first energise, but trips if the overcurrent continues beyond the rated threshold.

Suitable for protecting sensitive audio equipment, LED drivers, low-voltage power supplies, and control circuits where startup current spikes would cause a standard fast-blow fuse to fail prematurely. The 6 x 32mm glass tube format fits standard fuse holders in amplifiers, PA systems, stage lighting controllers, and AV distribution racks where IEC-compliant protection is needed.

The glass tube body allows visual inspection of the fuse element without removal from the holder — a blown fuse shows a visibly broken wire and darkened glass. The nickel-plated brass end caps provide reliable contact in clips and holders designed for 6 x 32mm tubes. Mercury fuses meet IEC 127 standards for time-delay characteristics and breaking capacity at the rated voltage.

Frequently Asked

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

Slow blow (time-delay) fuses tolerate brief overcurrent surges that occur at startup, typically holding for several seconds at 200-300% rated current before tripping. Fast blow fuses trip almost instantly at any overcurrent, protecting circuits where surge currents should not occur.

What equipment uses T1A slow blow fuses?

Common applications include audio amplifiers, PA mixers, LED dimmer packs, DMX controllers, low-voltage power supplies, and AV distribution equipment where inrush current at power-on would trip a standard fuse.

Are these fuses reusable after tripping?

No. Once the internal element melts and breaks the circuit, the fuse must be replaced. Attempting to bypass or repair a blown fuse creates a fire risk.

How many fuses are included?

Check the product specification or packaging for pack quantity. Mercury fuses are typically sold in packs of 5 or 10 for professional and trade use.
