Circuit Breakers are essential components of electrical systems. The purpose of a circuit breaker is to detect any overvoltage or overcurrent conditions in the electrical circuit and to provide an automatic way to disconnect and protect the circuit from damage. The LEGBX 66-39954-20-T is a compact and reliable switching device that can be used for a variety of applications in the electrical industry.

The LEGBX 66-39954-20-T meets the requirements of high-voltage electrical systems, and it is designed to provide reliable and safe switching operations without risking an overload or short circuit. The circuit breaker is constructed from durable, corrosion-resistant metals and is equipped with an integrated, reverse-polarity protection system. The LEGBX 66-39954-20-T can be used as an isolator switch, circuit breaker, or master switch in high-voltage applications.

The LEGBX 66-39954-20-T has a maximum voltage of 550V AC and a current rating of 20A AC. The device is designed to provide positive disconnection and open-circuit protection up to 10kA. The circuit breaker has a wide temperature range of -45⁰C to +45⁰C, and it is designed to operate in temperatures up to +85⁰C. The device has a UL 891 approval rating and is UL Recognized and CE approved.

The LEGBX 66-39954-20-T is suitable for a variety of applications in the electrical industry. The device is suitable for use in high-voltage electrical distribution and switching applications, and it can be used in industrial, commercial, and residential settings. It can be used in multiple circuits to provide protection for individual electrical systems or for an entire electrical system. The device can also be used in multiple circuits to isolate and disconnect sections of an electrically interconnected system.

The LEGBX 66-39954-20-T operates on the principle of thermal-magnetic operation. The device is equipped with an integrated thermal-magnetic tripping mechanism that senses an overcurrent or overvoltage condition in the circuit and reacts by opening the circuit, thus protecting the rest of the system from further damage. The thermal-magnetic tripping mechanism includes a thermal sensing element, a magnetic tripping element, and a reset element. The thermal sensing element detects the temperature rise in the circuit, and the magnetic tripping element senses the current flow in the circuit. If the temperature of the circuit rises above the threshold, or if the current flow in the circuit exceeds the threshold, the reset element will actuate, opening the circuit and stopping the flow of electricity.

In conclusion, the LEGBX 66-39954-20-T is an effective and reliable switching device that can be used for a variety of applications in the electrical industry. It is designed to provide positive disconnection and open-circuit protection up to 10kA, and it operates on the principle of thermal-magnetic operation. The device is UL Recognized and CE approved, and it is suitable for use in high-voltage electrical distribution and switching applications.
