Why Choose the Carlo Gavazzi RR2A40D400 Motor Reversing Relay?
The Carlo Gavazzi RR2A40D400 is a robust three-phase solid state motor reversing relay designed for reliable forward and reverse control of three-phase motors in industrial machinery and automation systems. As part of the Carlo Gavazzi RR2A series, it combines semiconductor switching with built-in interlocking, optoisolation and transient overvoltage protection in a compact panel-mounted package.
The RR2A40D400 electronically reverses a three-phase motor by switching two phases, providing an alternative to conventional electromechanical reversing contactor arrangements. Built-in interlocking prevents conflicting forward and reverse commands, while LED status indication provides clear visual feedback during operation. Zero-voltage switching helps reduce switching transients and electrical interference.
With a rated operational current of 11 A AC-53a, an operating voltage range of 40–440 V AC and a 10–40 V DC control input, the RR2A40D400 is suitable for three-phase motors rated up to 4 kW / 5 HP at 400 V. Its panel-mounted format and integrated reversing functionality make it a practical solid state solution for demanding industrial motor control.

Reliable Solid State Reversing for Three-Phase Motors
Three-phase motor reversing requires the phase sequence supplied to the motor to be changed so that its direction of rotation is reversed. The Carlo Gavazzi RR2A series performs this function electronically by controlling two phases, eliminating the mechanical contact wear associated with conventional reversing contactor arrangements.
The RR2A40D400 incorporates an interlock that prevents both directions from being activated simultaneously, together with optoisolated control inputs, transient overvoltage protection, zero-voltage switching and LED direction indication. These integrated functions simplify motor reversing circuits while providing dependable operation for machinery requiring frequent forward and reverse movement.
Typical Applications
- Industrial conveyors and material handling systems.
- Packaging and production machinery.
- Doors, gates and positioning equipment.
- Machine tools and automated handling systems.
- Forward and reverse three-phase motor control.
- OEM machinery and industrial automation systems.
