Material Composition
Housing: Flame-retardant reinforced plastic; Main contact: Silver tungsten alloy; Electromagnetic coil: High temperature resistant enameled wire; Bracket: Engineering plastic + metal parts.
Structural Characteristics
Integrated electromagnetic actuation structure; built-in thermal overload protection unit; combined main circuit and control circuit; standard wall/cabinet installation.
Working Principle
After the control circuit is powered on, the electromagnetic coil acts to pull in the main contact, switch on the main power circuit to start the motor; cut off the control power, the contact resets to cut off the motor power; the built-in protection unit acts when the motor is faulty.
Advantage Highlights
Stable electromagnetic actuation; complete protection functions; compact structure; excellent arc extinguishing ability; compatible with A-B whole set of automation products.
Applicable Industries
Factory automation, conveying equipment, fan and pump control, light and heavy industrial motor control systems.
Model Series
