Product benefits Compact and modern design IEC and UL approved Access global support and use the same products in all parts of the world Reliable in all networks. Resistor/Capacitor Circuit (RC) for Reduction of Electrical Noise in AC Contactor Coils. New designs reduce width and weight saving panel space. Soft starters and solid-state switching devices. 1, the main contacts rated voltage ≥ rated load voltage. Parameterization, Configuration and Visualization with SIRIUS. correct selection and maintenance of contactors in in- . ABB. Contactor - Construction, Operation, Application and Selection An electrical contactor is a switching device, widely used for the switching of motors, capacitors (for power factor correction) and lights. Hence, the required cable shall able to carry minimum 15A current. AC3 and AC1 categories Power ratings for motor starters and contactors vary by motor type. 2, the main contacts rated current ≥1.3 times the rated load current. Definite purpose contactors, electronic overloads, enclosed starters, enclosed manual motor starters and other contactor accessories are also DC contactors provide a cost-effective and reliable method to switch current in low-voltage DC circuits. 590+ Armature DC Contactor Option E:\JOB\PART\470XXX\595\HA\Issue 3\HA470595_iss3.doc Page 1 of 2 Issue 3 Application The 590+ DRV frames 1 and 2 are equipped with an AC (line-side) contactor that isolates the three-phase supply to the drive when the drive is stopped. Below is an example of an ABB motor's nameplate. Position and Safety Switches. Contactors and Overload Relays. Overload relays protect a motor by sensing the current going to the motor.
