Circuit Breakers are a type of switch that interrupts an electrical circuit when the current running through it exceeds a specific threshold. The PR21-4-8.00A-20394-1-V Circuit Breaker is a tripping mechanism for short circuit protection and overload operations. It interrupts the electrical current flowing through it once it has been tripped, protecting both the device and circuitry from damage.

The PR21-4-8.00A-20394-1-V Circuit Breaker is designed for industrial and commercial applications. It can be used in both alternating current and direct current applications, and is rated for 8.00A with a tripping threshold of 4A. It is cULus listed, which makes it approved for installation in both commercial and residential electrical systems in North America. It is capable of quick-make/quick-break operations and can disconnect a circuit in a fraction of a second, preventing any potential harm to the device or circuitry.

The working principle of PR21-4-8.00A-20394-1-V Circuit Breaker is based on the fact that when the current exceeds the preset value, the magnetic force generated by the increased current will cause the latch to move. This movement will cause the circuit to break. When the current drops below the preset value, the latch will return to its original position, and the circuit will be re-established.

The PR21-4-8.00A-20394-1-V Circuit Breaker is a reliable, cost-effective means of protecting both the device and the electrical system from damage caused by excessive current. It is typically used in industrial and commercial applications, and is capable of interrupting the electrical circuit in a fraction of a second. The PR21-4-8.00A-20394-1-V Circuit Breaker is cULus listed and approved for installation in both commercial and residential electrical systems in North America, making it an ideal choice for a wide variety of applications.
