Circuit breakers are an essential part of any electrical system. They are used to protect from excessive current or short circuits. The 1C63UR is a specific type of circuit breaker manufactured by ABB, a Swedish multinational corporation. This article will discuss the application field of the 1C63UR circuit breaker and its working principle.

Application Field of the 1C63UR Circuit Breaker

The 1C63UR circuit breaker is designed for use in industrial, commercial, and other applications. It is an advanced residual current circuit breaker (RCCB) that has been designed to provide superior protection against electric shocks. Its advanced features allow it to detect, prevent, and respond to hazardous or Earth fault currents safely and quickly. Additionally, its unique detection technique allows it to detect the second or multiple Earth faults in the same phase, ensuring that all hazardous conditions are eliminated.

The 1C63UR circuit breaker is suitable for installation in almost all indoor, dry/damp/humid environments, as well as flameproof and explosion-proof enclosures. It is also designed to be used in electrical systems with rated currents ranging from 40A to 63A and with rated voltages ranging from 380V to 690V. It can be used in AC and DC systems up to a frequency of 50/60Hz. Because of its wide application field and safety feature, the 1C63UR circuit breaker is ideal for use in all types of industrial, commercial, and residential applications.

Working Principle of the 1C63UR Circuit Breaker

The 1C63UR circuit breaker works according to the residual current mechanism that is embedded within it. This mechanism uses a current transformer (CT) and a comparator circuit to measure the difference between the two sides of the supply current. If any kind of difference is detected, then it triggers the circuit breaker to trip. This mechanism helps to protect against dangerous electrical shocks and other hazardous conditions.

The 1C63UR also features a special delayed Trip mechanism that simulates an Earth fault current before tripping. This helps to ensure that additional Earth faults are prevented as the RCCB can detect the second or multiple earth faults in the same phase. It also has a thermal compensation feature, which helps to ensure that the circuit breaker trips only after a certain temperature threshold is reached. Finally, the 1C63UR is also equipped with a special pulse time limiter which prevents false tripping by limiting the duration of the pulse sent through the power supply.

The 1C63UR circuit breaker is designed to be extremely reliable and efficient. With its wide application field, advanced features, and high-end safety features, it is an ideal choice for use in almost any type of installation. Its superior protection against electric shocks, hazardous conditions, and multiple Earth faults makes it a must-have for all types of electrical systems.
