FuseBox MT10B403

FuseBox MT10B403 40A Triple Pole 10kA B Curve MCB: Superior Protection for Industrial, Commercial, and Residential Applications.

Designed for use with Fusebox Consumer Units.

Ensure the safety and reliability of your electrical systems with the FuseBox MT10B403 40A Triple Pole 10kA B Curve MCB. Designed and manufactured by FuseBox, a trusted leader in electrical safety solutions, this Miniature Circuit Breaker (MCB) offers advanced protection against overcurrents and short circuits. Whether you need reliable circuit protection for industrial equipment, commercial buildings, or residential properties, the MT10B403 delivers exceptional performance and peace of mind.

Key Features and Benefits

High Current Rating: 40 Amps

The FuseBox MT10B403 MCB is rated for 40 amps, making it suitable for circuits with moderate to high current demands. This ensures that your electrical systems can handle significant power requirements without compromising safety, making it ideal for protecting medium-sized machinery, HVAC systems, and large residential appliances.

Triple Pole Configuration

The MT10B403 features a triple pole configuration, designed to protect all three phases in a three-phase electrical system. This comprehensive protection is crucial for industrial and commercial environments where three-phase power is common. By simultaneously disconnecting all three phases during a fault, the MT10B403 prevents potential damage to equipment and reduces the risk of fire.

Breaking Capacity: 10 kiloamperes (10kA)

With a breaking capacity of 10kA, the FuseBox MT10B403 can interrupt fault currents up to 10,000 amps. This high breaking capacity ensures that the MCB can safely handle severe short circuits and high fault currents, providing reliable protection for your electrical systems and minimizing the risk of damage or injury.

B Curve Tripping Characteristic

The B Curve tripping characteristic of the MT10B403 means it is designed to trip at lower fault current levels, typically between 3 to 5 times the rated current. This makes it suitable for protecting circuits with low inrush currents, such as lighting circuits and general-purpose outlets. The B Curve ensures fast response to overcurrents, enhancing the protection of sensitive equipment and reducing downtime.

Applications

Industrial Settings

In industrial environments, reliable circuit protection is paramount. The FuseBox MT10B403 is perfect for safeguarding motors, transformers, and other medium-duty equipment from overcurrents and short circuits. Its robust design and high breaking capacity ensure that it can withstand the rigors of industrial use, providing dependable protection in demanding conditions.

Commercial Buildings

For commercial buildings, the MT10B403 offers protection for essential systems like HVAC, lighting, and office equipment. Its ability to handle moderate to high current loads makes it ideal for commercial applications where power demand can be substantial. The triple pole configuration ensures comprehensive protection, maintaining the safety and functionality of critical systems.

Residential Properties

In residential settings, the FuseBox MT10B403 is well-suited for protecting circuits that power large appliances, home workshops, and other high-current devices. Its B Curve characteristic provides rapid response to overcurrents, protecting sensitive electronics and reducing the risk of electrical fires.
