Joslyn clark motor starters, contactors & control Products

Joslyn Clark

Joslyn Clark motor starters, contactors, control devices & legacy replacement parts. Authorized distributor since 1957. Emergency delivery for aging installations.

Electro-Kinetics has supplied Joslyn Clark motor control products for over six decades, serving industrial facilities with aging Joslyn Clark installations requiring replacement components and facilities seeking proven motor control technology. Whether you’re maintaining a 30 year old installation, need emergency replacement, or are evaluating upgrade options, we provide the knowledge that comes with support these products through their entire lifecycle.

Motor Contractors & Starters

Joslyn Clark manufactured comprehensive lines of motor contactors and combination starters serving industrial applications from fractional horsepower to large motors. Understanding model numbering, cross-references, and upgrade paths enables maintenance of aging installations.


Industrial contactors for motor switching applications. Joslyn Clark contactors in facilities range from small NEMA 00 frame sizes to large NEMA 6 and 7 contactors controlling hundreds of horsepower. Many of these contactors remain in service after 30+ years of operation.

Complete motor starter assemblies combining contactors, overload relays, and disconnects in single enclosures. Joslyn Clark combination starters and MCC buckets populate motor control centers in facilities nationwide. These assemblies present unique challenges when components fail.

Thermal overload relays protecting motors from damage caused by overcurrent conditions. Joslyn Clark overload relays integrated with contactors provide motor protection in aging installations. These overloads eventually fail requiring replacement or upgrade to modern electronic protection.


Control Devices & Accessories

Pilot devices, control transformers, and accessories that complete motor control installations. These components fail independently of contactors and starters requiring replacement without major panel modifications.


Operator interface devices allowing manual control and status indication. Joslyn Clark control devices in panels often outlast their mechanical lifespans requiring replacement for functionality or safety compliance.

Step-down transformers providing control voltage for Joslyn Clark motor control circuits. These transformers eventually fail from age, overheating, or insulation breakdown requiring replacement to restore panel functionality.


Maintenance & Upgrade Strategies

Beyond component replacement, facilities with substantial Joslyn Clark installations face strategic decisions about long-term maintenance approaches. We help facilities evaluate options balancing short-term needs with long-term investment strategy.


Facilities with aging Joslyn Clark equipment must choose between reactive emergency replacement and proactive planned replacement strategies. Each approach has cost implications and risk tradeoffs.

When Joslyn Clark components fail, facilities must decide whether individual component replacement makes sense or complete panel modernization provides better long-term value.
