Starter Accessories & Equipment

Starter accessories and equipment are used to support the control, protection, and maintenance of industrial motor starter systems. RSP Supply offers a wide selection of starter components, including auxiliary contact blocks, replacement coils, thermal elements, disconnects, and breakers for motor control and protection applications. These products are commonly used in control panels, machinery, motor starters, and industrial electrical systems where dependable switching, overload protection, and serviceability are essential.

Contactor auxiliary contact blocks are typically used in relay logic circuits to switch control voltage rather than motor power. Contactors themselves are used to switch larger amounts of electrical power and are commonly applied in electric motor control. Starter replacement coils are part of a contactor assembly and create the magnetic force that closes the power contacts when energized. When de-energized, the contactor opens and stops power flow to the motor. Starter thermal elements are used in overload relays to help protect motors by responding to excessive current and simulated motor heating, interrupting the control circuit before damage occurs.

Starter disconnects and breakers help provide manual isolation and automatic overcurrent protection within motor control systems. Circuit breakers interrupt excessive current automatically to help protect connected equipment, while disconnect switches allow operators to manually open or close the power path for maintenance and service. Together, these accessories and equipment help support safer operation, practical maintenance, and reliable motor starter performance across a wide range of industrial applications.
