IEL1-1REC4-21755-1-V

Circuit Breakers

The IEL1-1REC4-21755-1-V is a highly reliable low voltage circuit breaker that is well suited for a variety of application areas. It is a type of circuit breaker specifically designed for use in areas with elevated temperatures or where the system must be protected from overcurrent and short circuit events. The device has a range of protective features and is available in various sizes and designs to meet various application demands.

Application Field and Working Principle

The IEL1-1REC4-21755-1-V is used for the protection of electrical building wiring and equipment from overloads and short circuits. It is a universal low voltage device that is well suited for industrial, commercial, and residential applications.The circuit breaker works by automatically detecting and isolating a fault. When an overcurrent or short circuit is detected, the circuit breaker trips, cutting off the electrical connection between the supply and the load. The device then needs to be reset manually by pressing a button or a switch before electricity can flow to the protected area again.The IEL1-1REC4-21755-1-V features a trip current Auto Range function that automatically determines the exact trip current based on the requirements of the load area. This ensures that the circuit breaker only trips if the protection requirement exceeds the required current.The device also features a trip current lock function that prevents the adjustment of the trip current during operation. This prevents accidental adjustments from being made in the system without having to manually reset the breaker.The IEL1-1REC4-21755-1-V also has an adjustable delay time for the remote signal option. This allows the user to adjust the delay time for the signal to be sent in the event of a trip from a few minutes to up to 120 minutes.The IEL1-1REC4-21755-1-V is equipped with two separate circuit breakers that are connected in parallel. This ensures that a fault in one of the two circuit breakers does not cause the other to trip.The device is designed to be extremely reliable and durable. It has an operating temperature range of -20°C to +70°C and an insulation voltage of 1000 VAC. The device is also IP54-rated and complies with the IEC standards.In summary, the IEL1-1REC4-21755-1-V is a reliable and versatile low voltage circuit breaker that is well suited for a variety of applications and environments. It features an automatic trip current function, adjustable delay time for the remote signal option, and two separate circuit breakers connected in parallel. This makes the IEL1-1REC4-21755-1-V an ideal choice for residential and industrial applications alike.
