⇒Product introduction：

140CRP81100 molded case circuit breaker is a device used for overload long delay, short circuit instantaneous, with current limiting breaking ability. When the current in the circuit exceeds the set rated current value, the electromagnet or heat release device inside the circuit breaker will be activated, making the contacts in the circuit breaker quickly separate, thus interrupting the circuit and effectively avoiding the risk of electrical failure and fire.

Second, the working principle
The working principle of the 140CRP81100 plastic-case circuit breaker is based on the electromagnetic induction and heat release mechanism. When the current in the circuit exceeds the set rated current value, the electromagnet inside the circuit breaker will be activated, causing the contacts in the circuit breaker to quickly separate, thus interrupting the circuit. In addition, when a short circuit or overload occurs in the circuit, the heat release device inside the circuit breaker will also be activated, and the contact will be separated by rapid heat release, interrupting the circuit.

Third, 140CRP81100 application field
Home circuit protection: In home circuits, plastic-case circuit breakers are often used to protect circuits from overload and short circuit damage. Its fast break characteristics effectively cut the circuit, prevent damage to electrical equipment, and reduce the risk of fire.

Industrial production: In industrial production, plastic-case circuit breakers are widely used in the electrical protection of various equipment and machines to ensure the stable operation of the production line. Its reliability and durability make it an integral part of the industrial sector.
Construction engineering: In construction engineering, plastic-case circuit breakers are used to protect the electrical system inside the building to ensure the peace of mind and reliability of the circuit. Its compact design and ease of installation make it ideal for construction projects.
Transportation: In the field of transportation, plastic-case circuit breakers are widely used in the electrical systems of subways, trains and trams to ensure the safe operation of passengers and vehicles.

4. Purchase and precautions
When choosing a moulded case circuit breaker, the following points need to be noted:
Breaking capacity: According to the current of the protected equipment to determine the breaking capacity of the circuit breaker. In general, the breaking capacity of the circuit breaker should be slightly greater than the rated current of the protected equipment.
Rated voltage: The rated voltage of the circuit breaker must meet the voltage requirements of the device.
Operation mode: Select the appropriate operation mode according to the working environment of the device, such as manual operation or electrical remote control operation.
Protection level: Consider the protective performance of the circuit breaker, such as water, dust, etc., to provide a higher level of protection.
Manufacturers and brands: Choose manufacturers and brands with good reputation and reliable quality to ensure product performance and quality.
