filter_list

Benshaw molded case circuit breakers (MCCBs) are configured to protect electrical systems from overcurrent, short circuits, and other "events" that could lead to electrical system failure. They're used in industrial and commercial applications where reliable circuit protection is a must, and they're engineered to cover a wide range of current ratings, making them applicable to everything from small power panels to large power systems.

The durable molded case construction of Benshaw MCCBs allows them to withstand environmental challenges like moisture, dust, and extreme temperature changes. In even the most hostile environments, a molded case circuit breaker can deliver long-term performance and reliability. Benshaw MCCBs provide flexibility in how they can be used to protect your system. All the MCCBs have adjustable trip settings, which give the user the ability to set the protection level to accommodate the specific requirements of the system being protected.

What is a Circuit Breaker?

There are two different types of technologies that are commonly used in circuit breakers. 

Magnetic Breakers

Magnetic Breakers are designed to react to short circuits or sharp spikes in voltage and current. The more current that passes through the breaker’s electromagnet, the stronger the magnet becomes. When the current exceeds the rating for that particular breaker, the magnetic force becomes strong enough that it will pull the contact back and disconnect it from the other contact, disconnecting power from the device.

Thermal Protection Breakers

Thermal Protection Breakers protect against a sustained overcurrent, or a higher current, for a longer period of time. Thermal protection uses a Bimetal strip that will bend the contacts away from each other to disconnect power. Thermal Magnetic Breakers are the most common type of circuit breakers. They combine magnetic technology to protect against short circuits or sharp spikes and thermal technology that protects against sustained overcurrent for a long period of time.
