Circuit breakers are critical safety components in electrical systems, which are used to defend against dangerous conditions. The 8340-T120-K1M1-ALH126-3A is an example of a circuit breaker specifically designed for use in industrial facilities. The 8340-T120-K1M1-ALH126-3A is designed to be used in a wide range of applications, from high-voltage and high-amperage systems to low-voltage control circuit systems. In this article we will discuss the application field and working principle of the 8340-T120-K1M1-ALH126-3A circuit breaker.

The 8340-T120-K1M1-ALH126-3A circuit breaker is rated at 120A with a 600VAC interupt rating. It can be used in a variety of applications such as distribution systems, motor circuits, control panels, generator sets, and lighting systems. This circuit breaker is UL listed and CSA certified, making it suitable for hazardous locations. It has automatic overcurrent protection, a fast-acting thermal characteristic, and a manual overcurrent trip, making it especially useful in motors and applications with continuously operating loads.

The working principle of the 8340-T120-K1M1-ALH126-3A circuit breaker is based on the use of electromagnetic coils to control the current. When an overload or short circuit occurs, the current in the circuit is increased which creates a magnetic field around the coil. This magnetic field causes a spring-loaded armature to be pulled into the coil, breaking the circuit and disconnecting the power. The armature then detaches from the coil, allowing the circuit to reset.

When the circuit breaker trips due to an overload or short circuit, a trip indicator on the front panel of the breaker will light up. This indicator will stay on until the circuit is reset manually by the operator. The breaker can be reset by pushing a reset button located on the front panel of the breaker. The reset button must not be pushed until the fault has been corrected, otherwise the breaker will trip again.

The 8340-T120-K1M1-ALH126-3A Circuit Breaker is designed to provide reliable, high-quality protection to a variety of industrial systems. It can be used in a wide range of applications and is quick to trip when an overload or short circuit occurs. This helps to prevent damage to the electrical system and the surrounding equipment. The manual reset and trip indicator also make it easy to reset and verify the cause of the failure.
