Circuit breakers are essential components in industrial and domestic electrical and power distribution systems. They protect electrical installations from damage caused by overcurrent and overheating. The SU3C7UC circuit breaker is a popular circuit breaker used in industrial applications.

Introduction

The SU3C7UC circuit breaker is a rod-operated, three-pole dry type circuit breaker. It is designed for single-phase and three-phase applications. It is certified for use in hazardous locations, such as chemical plants and mines, which require circuit protection devices that can handle larger, long-duration overloads.

Application Field

The SU3C7UC circuit breaker is commonly used in industrial applications, such as:

• Chemical plants
• Mines
• Power stations
• Transportation systems
• Electric motor installations
• Oil, gas and petrochemical plants
• Data centers

Working Principle

The SU3C7UC circuit breaker operates on a "trip-free" mechanism. This means that the breaker will trip and open the circuit if the current exceeds the trip current setting. This setting is adjusted in the factory when the breaker is manufactured. The circuit breaker can be manually activated, as well as remotely, using a magnetic trip mechanism.

The circuit breaker is designed to protect both the load and the electrical system against overcurrent conditions caused by faults and overloads. The circuit breaker also provides short-circuit protection. When the circuit breaker detects a short-circuit, it immediately trips and opens the circuit, ensuring the overload current cannot damage the equipment.

Conclusion

The SU3C7UC circuit breaker is a rod-operated, three-pole dry type circuit breaker used in industrial applications. It is designed to protect both the load and the electrical system against overcurrent conditions caused by faults and overloads. It operates on a "trip-free" mechanism, and can be manually activated, as well as remotely. The SU3C7UC circuit breaker is certified for use in hazardous locations, such as chemical plants and mines, which require circuit protection devices that can handle larger, long-duration overloads.
