Circuit Breakers

IULHK11-1REC4-51-20.0-A-01 is a type of circuit breaker rated for 20.0 A. It is manufactured by IUL which is a subsidiary of REC4 Group, a Switzerland-based company that manufactures low-voltage electrical products. The circuit breaker is a protective device that helps protect electrical circuits by automatically interrupting current flow when a fault is detected. The device can be used to prevent overloads and short circuits, as well as provide protection against potential electrical shock and fire.

Including the thermal and magnetic trip unit, the IULHK11-1REC4-51-20.0-A-01 circuit breaker is composed of two functioning parts, the circuit breaker and the trip unit. The circuit breaker is responsible for the opening and closing of the current flow within the circuit, while the trip unit senses any increased current or overloading conditions that may be present in the connected circuit and when detected, signals the circuit breaker to trip, thus disconnecting the circuit.

Applications

The IULHK11-1REC4-51-20.0-A-01 circuit breaker can be used for various applications including providing protection for electrical motors, fresh water pumps, HVAC equipment, equipment used in hostile industrial environments, and other electrical equipment connected to a panelboard.

The circuit breaker comes with several settings such as current ratings, trip settings, and reset settings, making it very flexible and suitable for different applications. It is also designed with an adjustable time-delay feature which allows it to be customized for various function requirements.

The circuit breaker is also suitable for usage in hazardous area applications such as in petrochemical plants, paint shops, and pharmaceutical factories. It is very reliable and safe to use due to its compliance with international standards and its fire media attenuation design.

Working Principle

The IULHK11-1REC4-51-20.0-A-01 circuit breaker has two separate functioning parts. The circuit breaker part controls the opening and closing of current in the circuit, while the trip unit senses and responds to any overloads or short circuits in the connected circuit and signals the circuit breaker to trip. When the trip is activated, a small rotating flag within the trip unit triggers the breaker to open. This interruption of current flow helps protect the connected electrical circuit.

The trip unit is sensitive to both the temperature and current in the connected circuit. When either of these two parameters exceed the preset values, the trip unit triggers the breaker to open and interrupt the current. This helps protect the circuit from potential fire and electric shock hazard.

Conclusion

The IULHK11-1REC4-51-20.0-A-01 circuit breaker is designed for 20.0 A applications and manufactured by IUL Group. It has a thermal and magnetic trip unit and comes with adjustable settings. It is suitable for a variety of applications and can be used to protect against electrical shock, fire, and other potentially hazardous conditions. It is very reliable and a safe option for use in industrial, hazardous area, and other applications.
