1SDA126190R1 ABB RRD Motor 110–220 V AC/DC for Emax 3 E1.3

Why Choose the ABB 1SDA126190R1 RRD Motor for Emax 3 E1.3?

The ABB 1SDA126190R1, product designation RRD Motor 110–220 Vac/dc E1.3, is a Remote Racking Device (RRD) motor assembly designed specifically for withdrawable ABB SACE Emax 3 E1.3 circuit breakers. It enables motorised racking of a withdrawable breaker, allowing the breaker moving part to be inserted into or withdrawn from its fixed part without manually operating the racking mechanism at the switchboard.

Designed for a 110–220 V AC/DC supply, the 1SDA126190R1 package includes the RRD motor, power supply and controller. The system enables racking operations to be controlled remotely through an external control arrangement, helping personnel maintain greater distance from the switchgear during insertion and extraction procedures.

The RRD motor is specifically intended for the Emax 3 E1.3 frame size. Installation also requires the dedicated E1.3 RRD fixing kit, allowing the motorised racking equipment to interface correctly with the withdrawable breaker mechanism. This makes the accessory particularly useful in installations where remote operation, serviceability and personnel separation from energised switchgear are important considerations.

Remote Racking for Emax 3 Withdrawable Breakers

Withdrawable air circuit breakers normally require a mechanical racking operation to move the breaker between its operating positions. The ABB Remote Racking Device (RRD) motorises this process, allowing the Emax 3 E1.3 breaker moving part to be racked in or out through an external control arrangement rather than requiring the operator to perform the complete procedure manually at the breaker.

For the E1.3 frame, the 1SDA126190R1 provides the electrical RRD package comprising the motor, power supply and controller. A dedicated 1SDA126191R1 fixing kit is used to mechanically install the RRD on the E1.3 breaker. Together, these components provide an integrated remote-racking solution for service and operational environments where controlled breaker positioning and operator separation are desirable.

Typical Applications

• ABB SACE Emax 3 E1.3 withdrawable circuit breakers.
• Industrial low-voltage switchboards.
• Main incoming and distribution switchgear.
• Data centres and critical-power installations.
• Manufacturing and process-industry electrical systems.
• Utility and infrastructure switchgear.
• Generator and transformer distribution boards.
• Applications requiring remote breaker racking and improved service access.
