A contactor is a large relay, usually used to switch current to an electric motor or other high-power load. Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts.

This includes standard full NEMA sizes and motor matched half sizes exclusive to Siemens. Starters are available as open and enclosed with electronic overload protection, as well as a wide selection of accessories and spare parts.

The first item to consider is the load, which is measured in amperes. This load amperage is the amount of current required to power your device at the line voltage. It is important to know this at the line voltage you intend to use because the current will change with the voltage according to P=IV (sometimes referred to as P=VA), where P is …

Location. Katy, Texas. Occupation. EET. Nov 8, 2021. #1. I'm using a weg ssw-07 soft start.

Disconnect the incoming motor leads at the ac motor electrical conduit box. Check the motor starter leads for a phase-to-phase or a phase-to-ground short. If either of these two problems exists, check the motor lead wiring. If the motor starter leads are clear, move on to the motor.

Nature of sags. IEEE Std 1159 indicates that a voltage "sag" is a 10-90% decrease in rms voltage for a time period in the range from 0.5 cycle to 1 min. Figures 1 and 2 present typical data for severity and duration of sags. Of interest are those sags that cause contactor dropout and which can be eliminated in a cost-effective manner.

They're often used to shake and settle powders, flakes, and pellets in bins and hoppers. Motor is totally enclosed for use in environments with splashing water and dust. Every 10 pounds of dry material requires one pound of force to move it. If your bin has 200 pounds of dry material, you need a vibrator with at least 20 pounds of force.

The Citation line of contactors and starters was introduced in 1968 with many new features: the new CI non- wearing totally enclosed permanent air gap magnet structure; dual wound magnet coil with plug-in feature; color coded, twin break dust-safe contacts; and straight-through wiring.

Basic Contactor Construction. The contacts are the current carrying part of the contactor. This includes power contacts, auxiliary contacts, and contact springs. The electromagnet (or "coil") provides the driving force to close the contacts. The enclosure is a frame housing the contact and the electromagnet.

A contactor can stand on its own as a power control device, or as part of a starter. Contactors are used in applications ranging from the light switch to the most complex, …
