Circuit Breakers

Circuit Breakers are essential components in any electrical power systems. They are designed to protect the circuit from overcurrent or overvoltage and to protect personnel and equipment from electrical arc energy. The CB187P-25 is a highly reliable thermal circuit breaker used for overcurrent protection, overload protection and short circuit protection.

Application Field

The CB187P-25 is mainly used in mechanical and electrical, electronic equipment, power plants, industrial and mining enterprises, construction sites, ships, ships, telecommunications and electric power departments, and various laboratory test systems. It can be used to limit or prevent overloading of wires and overloads, and to prevent possible fire hazards and equipment damage caused by overloads and short circuits.

Working Principle

The CB187P-25 is a thermal circuit breaker which consists of several pieces of bimetallic strips and a push lever. The bimetallic strips are usually manufactured of two different materials with different thermal expansion rates. When the current flows through the bimetallic strip, it will produce an amount of heat due to the Joule effect which causes the bimetallic strip to bend. This will turn the push lever mechanism to open the circuit breaker, disconnecting the power supply from the circuit.

When the overcurrent is eliminated, the bimetallic strip will cool down and restore its original shape. This will reset the push lever mechanism, allowing the circuit breaker to close and turn the circuit back on. This cycle will repeat if the same fault occurs again, providing reliable overcurrent protection for a wide variety of applications.

The CB187P-25 is designed to operate under extreme temperature and environmental conditions, offering high durability and reliability in various applications. The circuit breaker comes with a robust construction and high heat resistance which can provide up to 5,000 on-off cycles to ensure a reliable operation. It has a high sensitivity to overcurrents, allowing it to trip at a very low current, preventing any damage to cables and electrical components.

The CB187P-25 is UL 508 approved, and is CSA certified for safe installation and use. The CB187P-25 is also rated for both residential and commercial applications and meets all the requirements for a reliable and safe circuit breaker.

Conclusion

The CB187P-25 from 2CS® is a thermal circuit breaker designed to protect from overcurrent, overload and short circuit. This circuit breaker has a robust construction and a high heat resistance for up to 5,000 on-off cycles, and it is UL 508 and CSA approved for reliable and safe operation. The CB187P-25 is a highly reliable circuit breaker suitable for a wide range of applications, from mechanical and electrical to power plants and industrial and mining.
