AOV2, AOV3 series motor protection circuit breaker ( the following refer to as circuit breaker) is suitable for AC 50/60HZ, rated voltage 690V, rated current 80A in circuit. Three-phase squirrel cage induction motor overload, short circuit, open phase protection and not frequent starting control purposes, can be used for power distribution line protection and not frequent load conversation, also can be used as an isolator.
Model specification：
Design features：
● Adjustable current setting value: it can be adjusted to the appropriate current value indicating position according to the actual working current.
● Can simulate mechanism trip design: through the TEST can make the mechanism trip, convenient simulation TEST.
Structural Features：
● Double new point structure: double break point of contact can suppress and disperse arc energy, improve the effort of eliminating isolated, improve the ability of connecting new points, reduce the electrical loss of melting head, and effectively improve the electrical life of the product.
● Thermal and magnetic comprehensive protection structure: the product has multiple protection functions of overload, short circuit and three-phase unbalanced.
