China Thermal Magnetic Molded Case Circuit Breaker Manufacturers, Suppliers, Factory
The thermal magnetic molded case circuit breaker (T-M MCCB) is a type of molded case circuit breaker that combines both thermal and magnetic trip mechanisms to provide comprehensive protection against overloads and short circuits. It is an advanced version of the traditional molded case circuit breaker that offers enhanced functionality and versatility.
Here are the key features and characteristics of a thermal-magnetic molded case circuit breaker:
Thermal Protection: The thermal component of the T-M MCCB provides protection against overcurrents caused by sustained or long-duration overloads. It uses a bimetallic strip that heats up when current exceeds the rated value, causing the circuit breaker to trip and open the circuit. The bimetallic strip's heating is proportional to the square of the current, ensuring reliable and accurate thermal protection.
Magnetic Protection: The magnetic component of the T-M MCCB offers instantaneous protection against short circuits and high-current faults. It utilizes an electromagnetic coil that generates a magnetic field. When a short circuit occurs, the high current passing through the coil causes the magnetic field to quickly actuate the trip mechanism, rapidly tripping the circuit breaker to interrupt the fault current.
Adjustable Trip Settings: T-M MCCBs usually feature adjustable trip settings for both the thermal and magnetic trip mechanisms. This allows users to customize the protection level based on the specific requirements of the electrical system and the connected equipment.
Breaking Capacity: T-M MCCBs are designed with high breaking capacities, which refer to their ability to interrupt and safely handle fault currents. The breaking capacity is typically specified as the short-circuit current rating (SCCR) and represents the maximum fault current level the circuit breaker can handle without sustaining damage.
Accessories and Features: T-M MCCBs can have additional features and accessories to enhance their functionality and convenience. These may include auxiliary contacts for remote monitoring and control, shunt trips for remote circuit breaker operation, undervoltage releases for voltage-dependent tripping, and lockout/tagout mechanisms for improved safety during maintenance and servicing.
Wide Application Range: T-M MCCBs are suitable for a wide range of applications, including residential, commercial, and industrial electrical installations. They are commonly used in distribution panels, switchboards, motor control centers (MCCs), and other power distribution systems.
Thermal-magnetic molded case circuit breakers offer reliable and comprehensive protection against overloads and short circuits. Their dual trip mechanism ensures effective and timely response to different types of faults, making them a popular choice for protecting electrical circuits and equipment in various settings.
