Description
The unitized Type AR switch is a distribution-level, loadbreak, gang-operated side-break switch designed to meet not only today’s needs but well into utilities’ future of distribution automation. Designed for nominal system voltages of 15kV, 27kV 34.5kV (Grd-Wye) or 38kV. The
Type AR switch is available with a variety of options, and in ratings for present and planned requirements.
To minimize field installation time, the Type AR switch is pre-assembled, adjusted and mounted on a crossarm.
Installation time is even faster for a Type AR switch with the hook stick-operation option.
The Type AR switch is available in five basic configurations:
● Horizontal ● Vertical ● Phase-over-Phase ● Delta •Inverted
All feature clockwise opening and are operable by torsional or reciprocating controls as well a hookstick operation option (full-length down-the-pole control or crossarm-mounted hook stick-operation control).
Full-length down-the-pole controls consist of Torsional swing-handle operation for Horizontal,Delta and Inverted switches and Reciprocating pumphandle operation for Vertical and Phase-over-Phase switches. (Standard Duty or Heavy Duty conrols are available for Vertical and Phase-over-Phase switches.) Switch open or close positions locking provisions are provided.
Offset control option for horizontal configuration allows the control to be trained down the side of the pole where interference prohibits mounting the control on the front of the pole.
Crossarm-mounted hook stick-operation controls provide pull-to-open / pull-to-close switch with maximum target hook stick accessibility.
Features:
All three phase switches feature a Roller Cam overtoggle mechanism to assure locked closed blades, mechanical advantage for easier open and close operation, and "snap" feedback to the operator。

Ultimate Guide to AC Contactor Abnormal Noise: From Electromagnetic Noise to Mechanical Vibration, Accurate Diagnosis and HandlingIn electrical control systems, AC contactors are among the commonly used electrical components, and they are also a common source of various electrical faults. After long-term use—especially in harsh environments with high levels of dust—AC contactors may sometimes emit squeaking or rattling noises after being pulled in and held. The causes of this phenomenon are analyzed as follows.Squeaking Noise After Pull-In and HoldingA fully functional AC contactor makes no noise when energized and pulledFelix Spark09/11/2025 -
Mismatched AC Contactor Sizing? These 4 Typical Issues You Must Not Ignore – Click to View SolutionsAC contactors (with the electrical schematic code KM) are core electrical devices used to control the connection/disconnection between power supplies and loads in circuits, and they are also common equipment that electricians need to work with regularly. In practice, it is not uncommon to find that some peers make mistakes in selecting AC contactors, leading to improper sizing and subsequent persistent issues. Here, four of the most typical common mistakes are highlighted for reference.I. Over-RJames09/11/2025 -

Proper Installation of AC Contactors | A Practical Guide to Avoid Burning and Misoperation, Master It in One ArticleAC contactors are widely used for switching and controlling power circuits. They use main contacts to open and close circuits, and auxiliary contacts to execute control commands. Main contacts typically only have normally open contacts, while auxiliary contacts often have two pairs of contacts with normally open and normally closed functions. Small-sized contactors are also frequently used as intermediate relays to work with main circuits, thereby achieving the function of remote control or contJames09/11/2025 -
Application and Maintenance of AC Contactors | Comprehensive Analysis of Common Fault Handling, Master It in One Article1 Analysis of Key Components of AC ContactorsAn AC contactor is an automated electromagnetic switch used for long-term, high-frequency switching of AC main circuits and control circuits. It features advantages such as automatic operation, under-voltage and no-voltage protection, high-capacity operation, strong stability, and low maintenance requirements. In the electrical control circuits of machine tools, AC contactors are mainly used to control electric motors and other loads.The key componentFelix Spark09/11/2025 -
Why Do Contactors Always Burn Out? Overload and Short-Circuit Protection Must Be Implemented SimultaneouslyContactors are used to close and open loads that require such operations during normal use, particularly for specific activities like medium-voltage public lighting and industrial electric motors.The medium-voltage contactor + fuse combination controller (F-C) can control motors up to 12 kV. However, medium-voltage controllers are also suitable as feeders for other types of loads, especially transformers. For such loads, contactors are usually modified to include mechanical latching, so that theEcho09/11/2025
