Motor starting cabinet

- Product Brief

JJ1 series motor starting cabinet is designed and manufactured according to the national standard GB7251.1 "Low-voltage switchgear and control equipment" and conforms to the International Electrotechnical Commission IEC298 "AC metal closed switchgear and control equipment" standard, meeting the DL402, DL404 standards. This series of products use autotransformer to compensate the voltage drop when starting the motor, and at the same time equipped with motor comprehensive protector. When the motor is out of phase or overloaded due to some reason, it can cut off the power supply in time to avoid the burning of the motor to the greatest extent.
