The IEG66-29770-1-V, an electric circuit breaker, is an ergonomically designed breaker with an integrated safety system. With an increased safety level, it is commonly used in various industrial electric power systems. This article will provide an overview of the IEG66-29770-1-V’s application field and working principle.

The IEG66-29770-1-V is applicable for use in household electric power systems, commercial electric power systems, and solar photovoltaic power systems, as well as other high-voltage electric power systems. It is designed to be used with four wires or five wires. For two-pole breakers, the IEG66-29770-1-V has a rated working voltage of 230/400V AC, and a rated working current of 63A.

The IEG66-29770-1-V features improved safety features. For example, its uniquely designed door-opening interlock provides protection against the risk of harm caused by any accidental contact with electrical equipment. Additionally, the IEG66-29770-1-V comes with an integrated interlocking device, which prevents the opening of the door when the switch gate is in any position other than the "off" position. This ensures that the switch cannot be opened without actually switching the circuit off.

The IEG66-29770-1-V works on a principle of transfer of energy within the circuit. When a current is applied to the breaker, the mechanism is activated and the breaker will open its contacts. This causes the current to flow from the main circuit to the output circuit and the main circuit is disconnected. This process is the same for both three-pole and four-pole breakers.

The IEG66-29770-1-V is also equipped with a tripping effect protection feature, which serves to protect its components against any high energy that could occur during a fault. In the event of a fault, the breaker will first disconnect the high-energy output and then tripping effect protection will take place. This is done to ensure that the equipment is protected against high currents and voltages, which could cause it to be damaged.

The IEG66-29770-1-V is an ergonomically designed circuit breaker that offers increased safety for industrial electric power systems. It is applicable for use in household electric power systems, commercial electric power systems, and solar photovoltaic power systems. Its unique door-opening interlock and integrated interlocking device provide added protection against accidental contact with electrical equipment. Additionally, its tripping effect protection feature offers additional protection against high currents and voltages. With its increased safety features, the IEG66-29770-1-V is well-suited for use in various industrial electric power systems.
