BOJACK Fast-Blow Glass Fuse Assortment Kit 200pcs 5x20mm & 6x30mm 250V

Description

Product Overview

The BOJACK 200‑piece fast‑blow glass fuse kit is engineered to meet the demanding needs of professional electricians, hobbyist technicians, and automotive repair shops. Each kit contains a balanced assortment of 5×20 mm and 6×30 mm glass cartridges, providing a full range of current ratings from 1 A up to 20 A at a safe operating voltage of 250 V. The fuses are manufactured from high‑quality borosilicate glass, offering superior thermal resistance and consistent blow characteristics that protect circuits from overloads and short‑circuits. The clear plastic storage case is designed with individual compartments, allowing users to quickly identify and retrieve the exact fuse needed without rummaging through loose components. This organization reduces the risk of selecting the wrong rating, which can lead to equipment damage or safety hazards. The kit’s compact dimensions (6.81 × 3.86 × 0.94 in) and lightweight construction (8.64 oz) make it easy to transport to job sites, service vehicles, or workshop benches. BOJACK’s reputation for durability and performance is reflected in the product’s high customer rating of 4.6 out of 5 stars, based on over 1,500 verified reviews.

Usage

This fuse assortment is suitable for a wide variety of applications. In residential settings, the 5×20 mm fuses are commonly used for lighting circuits, small appliance outlets, and thermostat controls, while the larger 6×30 mm fuses are ideal for motor starters, HVAC units, and larger appliance protection. Automotive technicians rely on the 6×30 mm series for engine control modules, power distribution units, and high‑current sensor circuits. The fast‑blow characteristic ensures that transient overloads are cleared quickly, preserving the integrity of downstream components. The kit is also valuable for educational institutions teaching electrical theory, as it provides students with hands‑on experience selecting appropriate fuse ratings for different load scenarios. Because the fuses are pre‑sorted by rating, users can efficiently perform maintenance, upgrades, or emergency repairs without the need to purchase individual fuses. The clear case allows for rapid visual inspection, making it an excellent choice for time‑critical troubleshooting in industrial environments where downtime directly impacts productivity.

FAQ

What does fast‑blow mean and when should I use these fuses?

Fast‑blow fuses are designed to open quickly when a current overload occurs, protecting sensitive components from prolonged exposure to excess current. They are ideal for circuits with transient spikes, such as motor start‑up currents, lighting loads, and electronic control modules.

Can I mix the 5×20 mm and 6×30 mm fuses in the same circuit?

Yes, as long as the selected fuse rating matches the circuit’s current requirement and the physical size fits the fuse holder. The 5×20 mm and 6×30 mm sizes are interchangeable in many standard cartridge holders, but always verify the holder’s specifications before installation.

How do I determine the correct fuse rating for my application?

Identify the maximum continuous current your device draws and select a fuse rating slightly above that value, typically 125‑150 % of the normal operating current. For example, a device drawing 8 A continuously would use a 10 A fuse to provide a safety margin while still protecting against overloads.

What should I do if a fuse repeatedly blows in the same circuit?

Repeated fuse failures usually indicate an underlying issue such as a short circuit, overloaded load, or a faulty component. Inspect the wiring for damage, verify that the load does not exceed the fuse’s rating, and consider using a higher‑rated fuse only if the circuit is designed to handle the increased current. If the problem persists, consult a qualified electrician for a thorough diagnosis.

Is the storage case durable enough for field work?

The case is made from impact‑resistant clear plastic with reinforced corners, providing protection against drops, dust, and moisture. It is lightweight for easy transport yet sturdy enough to endure the rigors of daily field use.
