The "Electric Operator FID, FOD" is a device that operates circuit breakers with a voltage of 36kV or lower. To prevent simultaneous operation of "open" and "close" from causing malfunctions, a circuit is incorporated to prevent the simultaneous excitation of the electromagnetic contactors for "open" and "close." Additionally, if the circuit breaker does not complete its operation after a specified time, a time-limited relay cuts off the circuit to prevent motor burnout. 【Features】 ■ Electric operator with a vertical operation type and an output of 500N·m ■ Operates circuit breakers with a voltage of 36kV or lower ■ Prevents motor burnout with a time-limited relay ■ Simple structure for easy maintenance *For more details, please refer to the PDF document or feel free to contact us.
