1SDA127015R1 ABB RRD Embedded 24V E4.3 Remote Racking Device

Why Choose the ABB 1SDA127015R1 RRD Embedded 24V E4.3?

The ABB 1SDA127015R1 is an integrated 24 V remote racking device (RRD-E) designed for use with ABB SACE Emax 3 E4.3 withdrawable low-voltage circuit breakers and switch disconnectors. As part of the ABB Emax 3 accessory range, it enables the circuit breaker to be electrically racked in and out, reducing the need for direct manual operation at the switchgear.

The RRD-E is installed within the withdrawable circuit-breaker assembly and provides motorised movement of the breaker between its racking positions. Remote racking is particularly valuable in industrial and commercial power distribution systems where operators need to manage switchgear while maintaining greater physical separation from the equipment.

Designed specifically for the Emax 3 E4.3 frame size, the 1SDA127015R1 uses a 24 V supply and is an integrated solution rather than the separate external RRD motor and mechanical fixing arrangement. ABB specifies this RRD-E accessory as being supplied with the circuit breaker or switch disconnector, ensuring correct integration with the E4.3 assembly.

Key Advantages

• Integrated remote racking device for ABB SACE Emax 3 E4.3 equipment.
• 24 V operation for integration into low-voltage control systems.
• Enables motorised insertion and withdrawal of compatible withdrawable circuit breakers.
• Allows racking operations to be controlled without direct manual operation of the breaker mechanism.
• Purpose-designed for the Emax 3 E4.3 frame size.
• Integrated design avoids the separate mechanical installation required by an external remote racking arrangement.

Remote Racking for Emax 3 Switchgear

Remote racking devices allow compatible withdrawable circuit breakers to be moved electrically through their racking mechanism rather than requiring the operator to perform the complete operation manually at the switchgear. This supports safer and more convenient operating procedures in electrical distribution installations where remote interaction with the breaker is desirable.

The ABB RRD-E solution integrates the racking mechanism into compatible Emax 3 equipment. The 1SDA127015R1 version is specifically intended for the E4.3 frame and operates at 24 V, providing a dedicated factory-integrated solution for motorised breaker insertion and withdrawal.

Typical Applications

• ABB SACE Emax 3 E4.3 withdrawable circuit-breaker installations.
• Low-voltage switchboards and power distribution systems.
• Industrial electrical distribution panels.
• Commercial and infrastructure switchgear installations.
• Remote operation of withdrawable circuit breakers.
• Applications requiring motorised breaker insertion and withdrawal.
