Introduction

The W58-XC1C18A-20 is a very popular circuit breaker used in a wide variety of applications. This breaker is manufactured by companies such as Siemens, Eaton, GE, and ABB, and has become a key part of many electrical systems. It is a two-pole circuit breaker, which has a rated load capacity of 1600 amps. In this article, we will discuss the W58-XC1C18A-20 application field, working principle, main structure, and testing requirements.

Application Field

The W58-XC1C18A-20 circuit breaker is widely used in a variety of industries, including industrial and commercial applications. This product is highly efficient and reliable, and it is commonly used in circuit breakers in motor control centers, motor control and systems, air conditioning units, and other common electrical tools. Additionally, it can also be used in specialized applications, such as for power factor correction, resonance protection, and static voltage limiting.

Working Principle

The W58-XC1C18A-20 circuit breaker operates with electro-mechanical or electronic control. It has two poles, which close when a trip is triggered by high current, or an overload is sensed. This circuit breaker can detect a fault current directly and it can also trip due to current feedback from an external relay or overload. Once the overload is detected, it immediately trips the circuit breaker and opens the contacts to interrupt the circuit.

Main Structure

The main parts of the W58-XC1C18A-20 circuit breaker include a base, a contact unit, a movable blade, a fixed blade, a terminals, a handle, and a shunt trip. The base is a metal frame that serves as the support and fixing point for the unit. The contact unit includes two pieces of metal that close when the breaker is open, and the movable blade is used to control the movement of the contact unit. The fixed blade is an optional part that can be used to prevent false trips. The terminals are used to connect the breaker to the power supply, and the handle is used to manually trip the breaker. The shunt trip can be used for remote tripping.

Testing Requirements

For the proper operation of the W58-XC1C18A-20 circuit breaker, testing is required. This testing should include a dielectric test, a contact resistance test, a leakage current test, a dynamic current test, a static current test, and a timer test. During the dielectric test, the resistance of the insulation of the contacts must be tested. The contact resistance test measures the resistance between the contacts and their respective terminals. The leakage current tests measure the leakage current between the contacts, and the dynamic and static current tests measure the response time for the breaker when it is tripped. Finally, the timer test measures the trip time for the breaker.

Conclusion

The W58-XC1C18A-20 circuit breaker is a reliable, efficient, and economical product that is well suited for a variety of applications. It is a two-pole breaker that is rated for 1600 amps, and it has a number of different parts, including a base, a contact unit, a movable blade, a fixed blade, terminals, a handle, and a shunt trip. This breaker utilizes electro-mechanical or electronic control to detect a fault current or an overload. In order to ensure that the breaker is functioning properly, testing is required, which includes dielectric, contact resistance, leakage current, dynamic current, static current, and timer tests.
