Industrial Starter Accessories
Industrial starter accessories are essential components in motor control systems, supporting safe, reliable, and efficient operation of electric motors. RSP Supply offers a wide selection of starter accessories, including contactors, auxiliary contact blocks, replacement coils, connection kits, contact kits, heater elements, and overload relays. These components are used across manufacturing, processing, and automation environments where dependable motor control is required.
Contactors are electrically controlled relays designed to switch high-power loads, most commonly electric motors. They typically feature normally open power contacts that close when the coil is energized, allowing current to flow to the motor. Auxiliary contact blocks are often added to contactors to support control and relay logic circuits, frequently operating at lower control voltages such as 120VAC rather than motor voltage.
Overload relays and thermal heater elements provide critical motor protection by monitoring current flow and indirectly measuring motor heating. When current exceeds preset limits for a prolonged period, the overload relay interrupts the control circuit, causing the contactor to open and disconnect power to the motor. Together with disconnects and circuit breakers.

FAQs
Q: What are industrial starter accessories used for?
Industrial starter accessories are used to control, protect, and support the operation of electric motors in industrial motor control systems.
Q: What is the purpose of a contactor?
A contactor is a relay designed to switch high electrical loads, commonly used to start and stop electric motors through a control circuit.
Q: What does a starter replacement coil do?
A replacement coil energizes the contactor, creating a magnetic field that closes the power contacts and allows current to flow to the motor.
Q: How do overload relays protect motors?
Overload relays monitor current flow to the motor and interrupt the circuit if excessive current is detected over time, preventing motor overheating and damage.
Q: How do contactors and overload relays work together?
Contactors and overload relays are wired in series so that if an overload condition occurs, the overload relay opens the control circuit, causing the contactor to disconnect power to the motor.
