Regarding of the molded case circuit breaker mold the most popular products, which is the automatic Tripping Devices possessed 3 types of thermal –magnetic type of the molded case circuit breaker mold, hydraulic-magnetic type and electronic type. The first one is trip with the power of bimetal and electromagnet of the molded case circuit breaker mold, which has an overcurrent heats and warps the bimetal to trip by rotate the trip bar. 2 If the overcurrent is excessive, movable core rotates clockwise and the armature is attracted and to trip by rotate the trip bar of the molded case circuit breaker mold. The second is the trip with the power of electromagnet.

1. At an overcurrent flow, the magnetic force of the coil overcomes the spring; the core closes to the pole piece, attracts the armature, and actuates the trip bar of the molded case circuit breaker mold. The delay is obtained by the viscosity of silicon oil of the molded case circuit breaker mold. For another case, if the overcurrent is excessive, the armature is instantly attracted, without the influence if the moving core.

Molded case breaker are essential components in electrical systems, providing effective and reliable protection against electrical faults. Their versatility and robust features make them suitable for a wide range of applications, from residential installations to industrial and power distribution systems.

Molded case circuit breakers (MCCBs) are devices that protect electrical systems by interrupting the flow of current in the event of a fault or overload. molded case circuit breakers are widely used in various industries and commercial buildings due to their advantages, including:

1. Wide range of applications: MCCBs can be used in a variety of applications, from low voltage switchboards, motor control centers, to power distribution systems. Different models are available to fit specific applications, ensuring maximum protection for electrical equipment.

2. Reliable protection: With advanced trip units and accurate sensing mechanisms, MCCBs can provide high-quality protection against overloads, short circuits, and ground faults. This can prevent damage to equipment and avoid costly downtime.

3. Easy to install and maintain: MCCBs are designed for easy installation and maintenance, with features such as standardized mounting systems and plug-in connections. This can save time and reduce the need for specialized expertise.

4. Cost-effective: Compared to other types of protection devices, such as fuses, MCCBs are more cost-effective in the long run. MCCBs can be reset after tripping, eliminating the need to replace components every time there is a fault or overload.

5. Configurable settings: MCCBs can be customized for different protective settings, such as overcurrent and ground fault protection. This can ensure that the MCCBs are optimized for different applications and give customers greater flexibility in selecting protection settings.

6. High breaking capacity: MCCBs can handle high short-circuit currents and have high breaking capacities. This means they can quickly and safely interrupt a fault, minimizing damage to equipment and ensuring the safety of personnel.
