Circuit breakers are an essential part of safety systems in both commercial and residential buildings. They serve to prevent a potentially hazardous electrical overload from happening, by automatically shutting off the power supply if the current is too high. The 1658-G21-00-P10-16A is a type of circuit breaker designed for low-voltage applications. It is important to understand the application field and working principle of this device in order to get the most out of it.

Application Field

The 1658-G21-00-P10-16A is primarily used in domestic applications. It is most often employed in switchboards, and is one of the most commonly used circuit breakers in home installations. In addition, the device is also often found in motor controls, transformer panels and switchgear. As a safety device, it is also used in applications where it must trip with a specified current threshold, such as in an emergency stop circuit.

Working Principle

The 1658-G21-00-P10-16A is designed to protect against overload or short-circuiting, by automatically shutting off the electrical supply when the current exceeds a certain level. The mechanism which makes this possible is fairly simple. The device is fitted with a temperature sensitive bimetallic strip, which is attached to a set of contacts located within the circuit breaker. This strip is heated by the electrical current flowing through the device, causing it to bend until it touches the contacts, thus causing the circuit to break. As the current in the circuit drops, the strip cools down and resets itself. This cycle can be repeated many times until eventually, the circuit breaker has to be replaced.

In order to ensure that the device operates efficiently, it is important to set the trip level of the circuit breaker at the right value. This value is determined by the size of the load that the circuit breaker is supplying, as well as the type of circuit it is connected to. Manufacturers will usually provide a guide as to how to set the trip level for a given application.

Though the 1658-G21-00-P10-16A is designed primarily for domestic use, it can also be utilized in commercial or industrial settings. The device is suitable for use with up to 16A of current and can be employed in a variety of applications. As such, it is a versatile and reliable choice for many types of circuit protection.

The 1658-G21-00-P10-16A circuit breaker is an invaluable safety device, which helps to protect circuitry from an overload or short-circuit. The device is relatively straightforward to install and simple to adjust, making it a convenient choice for many types of applications. Understanding the application field and working principle of the device is key to getting the most out of it.
