20 A MCB

Ensure the safety of your electrical systems with high-quality MCBs. These miniature circuit breakers offer reliable protection against overloads and short circuits. The MCBs are effective options owing to their flexibility for resetting and reuse. Moreover, they are also easy to install.

Among the various options, a 20 A MCB is suitable for residential, commercial, and industrial applications. Explore its key features and details to make the right choice.

Description of 20 A MCB

A 20 A MCB offers protection from the harm possible due to excess current flow. Tripping on exposure to over 20 Amperes of current breaks the circuit, preventing equipment failure and fire incidents. It can be manually reset after tripping, allowing easy restoration of power.

Specification of 20 A MCB

The specifications to consider when going to buy 20 A MCB online or offline include the following:

Current and Voltage Rating

The current rating of 20 Amp MCB will be 20 Amperes, indicating that it is the maximum current it allows before tripping. The voltage rating will typically vary between 230 V to 400 V.

Breaking Capacity

It refers to the maximum fault current the MCB can safely interrupt. The value commonly ranges from 4.5 kA to 15 kA.

Tripping Curve

The tripping curve can be B, C or D type. The B curve offers the fastest tripping and is commonly used in residential settings. The C curve is suitable for moderate applications like in-rush currents. The D curve is designed to handle very high in-rush currents generally found in industrial settings.

Number of Poles

This specification indicates the number of separate electrical circuits that the breaker can protect. It can be single, double, triple or four-pole. Single pole protects single-phase circuits, and double pole disconnects both phase and neutral. The triple pole is used in three-phase systems while the four pole does the same along with a neutral.

Terminal Capacity

It specifies the range of conductor sizes that can be securely connected with MCB. It prevents loose connections, which may result in overheating.

Standard Compliance

This is an important specification, among others, that influences the 20 Amp MCB price. It must be considered as indicative of the quality of 20 A MCB. The product will be an IEC or EN complaint.

Benefits of 20 A MCB

The advantages of 20 A MCB are as follows:

• Safety from excess flow of current that can lead to damage to the equipment and fire.
• The reuse facility offers convenience, eliminating the need to buy a new piece and install it again. Hence, it also provides interrupted protection.
• 20 A MCB requires minimal maintenance and works with high accuracy.

Applications of 20 A MCB

The MCB 20 A can be used in residential, commercial and industrial settings. It is suitable for use with:

• lighting systems
• low-power devices
• water heaters
• small appliances such as coffee makers, toasters, blenders, and microwaves
