Starter Contactor Accessories
Starter contactor accessories are used to expand functionality, improve monitoring, and extend the service life of motor control equipment. RSP Supply carries a full line of starter contactor accessories from trusted manufacturers, including Eaton and ABB. These components are designed to meet the demands of industrial motor control applications and support reliable operation in a wide range of environments.
Common starter contactor accessories include auxiliary contact blocks, overload relays, and surge suppressors. Auxiliary contacts operate in tandem with the main contactor, providing additional normally open or normally closed signals for remote indication, sequencing, or interlocking with other control devices. This allows multiple devices or circuits to be coordinated safely and efficiently within a motor control system.
Surge suppressors help protect contactors and connected equipment from voltage spikes and transient overvoltages caused by motor switching or inductive loads. By reducing electrical stress on coils and control circuits, these accessories contribute to improved system reliability and longer equipment life. When properly selected, starter contactor accessories enhance performance while maintaining compatibility with existing motor control hardware.
FAQs
Q: What are starter contactor accessories used for?
Starter contactor accessories are used to add functionality, monitoring capability, and protection to contactors used in industrial motor control systems.
Q: What is an auxiliary contact on a starter contactor?
An auxiliary contact provides an additional output that mirrors the operation of the main contactor, allowing status indication, control sequencing, or signaling to other devices.
Q: Are overload relays considered starter contactor accessories?
Yes, overload-related components work alongside contactors to protect motors by interrupting the control circuit during prolonged overcurrent conditions.
Q: What does a starter contactor surge suppressor do?
A surge suppressor protects contactor coils and control circuits from voltage spikes and transient overvoltages that can occur during motor operation.
Q: Does the manufacturer matter when selecting starter contactor accessories?
Yes, selecting accessories from the same manufacturer as the contactor helps ensure proper fit, electrical compatibility, and reliable performance.
