Reversing Combination Starters
Reversing combination starters are integrated motor control assemblies designed to start, stop, and reverse the direction of electric motors while providing coordinated overload and short-circuit protection. RSP Supply offers a broad selection of NEMA reversing combination starters featuring melting alloy overload relays and Mag-Gard circuit breakers, commonly used in applications such as conveyors, hoists, cranes, and industrial machinery where bidirectional motor operation is required.
These starters combine multiple motor control components into a single enclosure, including forward and reverse contactors, overload protection, and a disconnecting means. The contactors manage power delivery and motor direction, while melting alloy overload relays protect motors from prolonged overcurrent and overheating conditions. Mag-Gard circuit breakers provide reliable short-circuit protection and help safeguard both the motor and upstream electrical equipment.
Available in a range of NEMA sizes, reversing combination starters can be properly matched to motor horsepower, voltage, and duty cycle requirements. Enclosed designs provide organized wiring, enhanced safety, and compliance with NEMA standards. These assemblies are widely used in manufacturing, material handling, automation, and other industrial environments that demand dependable motor reversal and protection.
FAQs
Q: What is a reversing combination starter?
A reversing combination starter is a motor control device that allows an electric motor to run in both forward and reverse directions while providing overload and short-circuit protection within a single enclosure.
Q: What applications require reversing motor control?
Reversing motor control is commonly required in conveyors, cranes, hoists, machine tools, and material handling systems where directional changes are part of normal operation.
Q: What is a melting alloy overload relay?
A melting alloy overload relay uses heat generated by motor current to activate a trip mechanism when excessive current persists, helping protect the motor from overheating.
Q: What is a Mag-Gard circuit breaker used for?
Mag-Gard circuit breakers provide short-circuit and overcurrent protection by interrupting power during fault conditions, protecting motors and electrical systems.
Q: How do I choose the correct NEMA size for a reversing combination starter?
Selection depends on motor horsepower, voltage, current rating, and application requirements. The NEMA size must be properly matched to ensure safe and reliable operation.
