CB185P-25 Circuit Protection

Circuit breakers are a vital element in any electrical system - they are the protective devices which detect the fault conditions in the system, and open the connection so that no further current flows. The CB185P-25 is a kind of circuit breaker with a number of applications and uses. In this article, we will discuss the application field and working principle of the CB185P-25.

Application Field

The CB185P-25 is a compact circuit breaker designed for applications in low- and medium-voltage systems. It is a single-pole breaker and is suitable for use in distribution boards, switchgear, and control panels. It is usually applied in industrial and commercial electrical protection systems, and may also be used in the residential and light industrial sectors. The CB185P-25 can be used to protect against the full range of overcurrent and short circuit conditions. Additionally, its double insulation configuration increases safety and reliability in operation.

Working principle

The CB185P-25 circuit breaker operates in accordance to the thermal-magnetic principle, which combines both the thermal effect and the magnetic effect to provide optimal overload protection. In the case of overload or short circuit, the current will rise rapidly and cause the temperature of the tripcoil to increase. As the temperature rises, the electric arc is weakened and eventually extinguished. Simultaneously, a magnetic force is generated which forces the breaker arm to contact the main contacts and open the circuit. This ensures that the system is protected from any further damage. The CB185P-25 also includes a ‘hold-in’ feature: when the circuit breaker senses a fault condition, it will open the circuit and wait for the fault to be cleared before it will allow the current to flow again. This ensures that the circuit is protected until the fault is cleared.

Conclusion

The CB185P-25 circuit breaker is a single-pole breaker designed for the protection of low- and medium-voltage systems in a variety of commercial and industrial applications. Its operation is based on the thermal-magnetic principle, which combines both the thermal effect and the magnetic effect to ensure optimal overcurrent protection. Additionally, the CB185P-25 includes a ‘hold-in’ feature to ensure that the circuit is protected until the fault is cleared. Overall, the CB185P-25 is a reliable and effective circuit breaker for low- to medium-voltage applications.
