Circuit Breakers

Circuit breakers are essential and mission-critical components of electrical systems, providing safety and peace of mind by monitoring and protecting electrical circuits from damage or potential problems, such as overcurrent or overloads. In this article, we explore the application field and working principle of the 3400-IG1-P10-SI-0.2A circuit breaker.

Application Field

The 3400-IG1-P10-SI-0.2A circuit breaker is designed to protect medium-voltage (MV) industrial electrical systems, typically in companies where the electricity load is higher than the supply capacity. This type of circuit breaker is suited for both indoor and outdoor installations for either manual or automatic control of circuits.

The 3400-IG1-P10-SI-0.2A circuit breaker combines advanced safety features with a robust build quality and reliable operation. It is designed to meet the requirements of IEC/EN 60947 certification standards and is able to break currents of up to 0.2A.

Working Principle

The 3400-IG1-P10-SI-0.2A circuit breaker is an insulated case-type breaker that incorporates two separate insulated contacts. When an excessive current flows through the circuit, the thermal element inside the breaker starts to heat up, activating the spring-loaded mechanism. This causes the breaker contacts to separate and the circuit is then safely and securely disconnected from the power source.

The breaker incorporates a number of safety features, such as Arc-Fault Current Interruption (AFCI). This technology helps to minimize the risk of fire due to arc flash and helps to reduce the cost of electrical repairs in case of fault. The breaker also features Overcurrent Detection (OCD) that is able to detect any changes in electrical flow and will disconnect the circuit if a fault or problem is detected. It also includes a Manual Disconnect feature that allows the user to manually turn off the breaker in case of an emergency or power outage.

In addition, the 3400-IG1-P10-SI-0.2A circuit breaker is equipped with a built-in bypass switch. This allows the user to switch the circuit breaker on and off without having to turn off the entire electrical system. This is especially useful for maintenance and servicing activities, as it helps to minimize disruption to the system.

Conclusion

The 3400-IG1-P10-SI-0.2A circuit breaker is designed for use in medium-voltage industrial applications and provides a safe and secure method of controlling, monitoring and protecting circuits from damage or overloads. It is equipped with a number of advanced safety features, and its robust build quality makes it a reliable and efficient choice for industrial electrical systems.
