Circuit Breakers

IALK1-1-51-16.0-AV-01 application field and working principle

Circuit breakers are electronic devices that protect electrical systems from overloads and short circuits. The IALK1-1-51-16.0-AV-01 is a specific type of circuit breaker used in industrial applications such as power supplies and motors. It is designed to detect and interrupt any over-current situation, providing reliable protection against excessive amperage or voltage.

The IALK1-1-51-16.0-AV-01 is an ABB-manufactured air-break circuit breaker. It has a voltage rating of 1600V, a rated current of 51A, and a short-time breaking capacity of 15kA. It is equipped with a thermal-magnetic fuse and an auto-reset feature. The device is designed to provide reliable protection against fault currents, overloads and short-circuits and comes with a comprehensive selection of accessories.

The IALK1-1-51-16.0-AV-01 circuit breaker works by using a combination of mechanical and thermal components. On the mechanical side, the device contains a trip bar or lever that is connected to a spring. This spring is designed to open the circuit breaker contacts when a certain amount of current is detected. On the thermal side, there is a temperature-sensitive element that activates the trip bar when it reaches a certain temperature.

When an over-current situation is detected, the thermal element heats up and activates the trip bar, which in turn, opens the circuit breaker contacts, interrupting the current. If a short-circuit is detected, the thermal element detects this and activates the trip bar in milliseconds.

The IALK1-1-51-16.0-AV-01 circuit breaker is suitable for various industrial applications, such as heating, ventilation and air-conditioning (HVAC) systems, power plants, wind turbines and solar systems. It is designed to provide reliable protection against overloads, short-circuits, or any other over-current situation.
