IEGBX1-35205-20R-V application field and working principle

Circuit breakers are widely used in all kinds of motor control systems as protection components. The IEGBX1-35205-20R-V is a common type of circuit breaker produced by Romonen Electric Ltd. mainly used in motor control application fields.

The IEGBX1-35205-20R-V is a 3-pole circuit breaker with voltage rating of 24VDC. It has a current rating of 20A and is designed for circuit protection of DC motor, traction motor and various kinds of DC armature circuits. It also can be used in series, parallel, as well as other combinations of DC motor drives, to protect against short-circuits, overloads, and ground faults.

The working principle of the IEGBX1-35205-20R-V circuit breaker is based on its thermal-magnetic element. It is composed of a sensitive thermistor and a current-sensitive magnetic particle core. The thermistor senses temperature rise in the contact surface and an increase in current in the relay coil to trips the circuit breaker instantly. In the case of an overload or short circuit, the circuit breaker will be tripped and the circuit will be opened. The current-sensitive magnetic particle core supplies additional power to the relay coil to provides additional protection.

Overall, the IEGBX1-35205-20R-V circuit breaker provides reliable protection for applications involving DC motors. Its thermal-magnetic element is able to detect overloads and short-circuits and trip the circuit breaker quickly to protect the motor.
