NewElec's 330 Series motor protection relays are designed to meet the protection demands of wound rotor motors used on winches, overhead cranes and winders taking into consideration their unique duty class, starting class, cyclic duration factors and motor loading.
The relays provide overload protection permitting the motor to be used to its full capacity, and accurate thermal protection, taking into account the motor duty class and CDF. Protection is also provided against unbalance and phase loss with user-selectable detection thresholds (2 to 40%).
The 330 Series continuously calculate heating and cooling rates, ensuring that motor loading and CDF are maintained within the tolerable thermal envelope of the protected motor. A crane cubicle-mounted load/thermal measurement meter assists the crane operator to steer away from an impending trip condition, resulting in less downtime.
Easy to set load and unbalance setting dials as well as latched trip diagnosis LEDs indicate the operating condition to assist maintenance personnel. The relays are available for either chassis or flush door mounting.
The 330 Series motor protection relays are designed for all crane, winch and winder motor applications where accurate, reliable overloading and unbalance protection is required.
