BOJACK 20 Pack Slow‑blow Glass Fuse 1A 250V for Electronics

Description

Product Overview

BOJACK presents a high‑quality set of 20 slow‑blow glass cartridge fuses designed for precise over‑current protection in electronic circuits. Each fuse measures 5 mm × 20 mm (0.2 × 0.78 in) and is rated for 1 A at 250 V, delivering a time‑delay characteristic that tolerates brief current surges while safeguarding components from sustained overloads. The fuses are housed in a compact, reusable plastic storage case that keeps them organized and protected from moisture and mechanical damage.

Usage

These fuses are ideal for hobbyists, repair technicians, and small‑scale manufacturers who need dependable protection for power supplies, LED drivers, audio equipment, and other low‑voltage electronics. Install the fuse in series with the load, ensuring the correct orientation if the fuse features a marked polarity. The slow‑blow design is especially useful in applications where inrush currents are common, such as motor start‑up or transformer energization.

Why Choose Us

BOJACK leverages decades of experience in electrical components to deliver fuses that meet stringent safety standards.

FAQ

What does “slow‑blow” mean?

Slow‑blow (time‑delay) fuses allow short, high‑current spikes to pass without opening, protecting devices that experience inrush currents while still cutting off sustained overloads.

Can I replace a blown fuse with any other type?

For optimal safety, replace with a BOJACK 1 A 250 V slow‑blow glass fuse. Using a different rating may affect circuit protection and could lead to component damage.

Is the storage case reusable?

Yes, the plastic case is designed for repeated opening and closing, making it convenient for ongoing projects and inventory control.

Are these fuses suitable for AC or DC circuits?

They are rated for both AC and DC applications up to 250 V, making them versatile for most low‑voltage electronics.

How do I identify a blown fuse?

Inspect the glass element; a blown fuse will show a broken or melted wire inside the glass envelope, often accompanied by a darkened appearance.
