Glass Fuse 10A – 250V (Size T5x20mm)

Description

Glass Fuse 10A – 250V (Size T5x20mm)

A glass fuse is a protective component that is commonly used in electrical circuits to prevent damage caused by excessive current. The 10A indicates the current rating, and the 250V represents the maximum voltage rating that the fuse can handle. The T5x20mm size refers to the dimensions of the fuse, with a 5mm diameter and 20mm length.

Key Features:

1. Current Rating:
   • 10A: The fuse is designed to protect the circuit from overcurrent conditions. It will blow (break the circuit) when the current exceeds 10 amperes, preventing damage to the components in the circuit.
2. Voltage Rating:
   • 250V: The fuse can handle a maximum voltage of 250V across the circuit. If the voltage exceeds this value, the fuse may not function properly, and there’s a risk of failure.
3. Size:
   • T5x20mm: This fuse has a standard size of 5mm in diameter and 20mm in length. The T5x20mm size is a widely used fuse format, especially in lower power circuits.
4. Glass Body:
   • The fuse features a transparent glass body, allowing for easy visual inspection. This makes it easier to detect when the fuse has blown, as the glass will appear broken or cloudy if it has been triggered.
5. Blow Characteristics:
   • The fuse is designed to blow (open the circuit) when the current exceeds the rated value (in this case, 10A) for a certain duration. Once blown, the fuse needs to be replaced to restore the functionality of the circuit.

Applications:

1. Overcurrent Protection:
   • The primary function of this glass fuse is to protect circuits from overcurrent conditions that could damage sensitive components like transistors, ICs, and LEDs. If the current exceeds 10A, the fuse blows, breaking the circuit and preventing further damage.
2. Power Supply Protection:
   • Commonly used in power supply circuits to protect against short circuits or sudden current surges. This fuse can help prevent damage to power transformers, rectifiers, and other power supply components.
3. Consumer Electronics:
   • This fuse is commonly found in consumer electronic devices, such as TVs, audio equipment, computers, and home appliances, to protect against excessive current flow that could result from power surges, faults, or short circuits.
4. Automotive Circuits:
   • Glass fuses are also used in automotive circuits to protect components like DC motors, lightning circuits, and control circuits that require protection from overcurrent.
5. Home Appliances:
   • It is widely used in household electrical appliances to safeguard against overcurrent conditions that could damage the appliance’s internal components or wiring.
6. HVAC and Electrical Equipment:
   • Used in heating, ventilation, and air conditioning (HVAC) systems, as well as other industrial electrical equipment, to avoid overcurrent damage.

Advantages of Glass Fuse 10A – 250V:

1. Quick Response Time:
   • Glass fuses have a very fast response time when overcurrent conditions occur. This ensures that the circuit is protected almost immediately, minimizing damage to sensitive components.
2. Easy to Replace:
   • Once blown, a glass fuse is easy to replace. Since the fuse is a simple, single-use device, replacing it is often more cost-effective and quicker than repairing damaged circuit components.
3. Visual Inspection:
   • The transparent glass body allows for easy visual inspection. If the fuse has blown, you can immediately see the broken filament inside and know that it needs replacement.
4. Wide Availability:
   • Glass fuses in the T5x20mm size and with 10A/250V ratings are widely available, making it easy to find replacements for any application.
5. Cost-effective Protection:
   • Fuses are a low-cost solution to protect circuits, and glass fuses are especially affordable, making them a popular choice for both consumer electronics and industrial equipment.
