1SDA085528R1 ABB SACE Emax 2 Remote Racking Device

Why Choose the ABB Emax 2 Remote Racking Device?

The ABB Remote Racking Device (RRD), order code 1SDA085528R1, is a dedicated accessory for ABB SACE Emax 2 E2.2 through E6.2 withdrawable circuit breakers. Designed to operate the circuit-breaker racking mechanism without requiring the operator to stand directly in front of the switchgear, it provides a practical solution for remotely moving a compatible breaker between its connected, test and disconnected positions.

The 1SDA085528R1 version operates from a 100–127 V AC/DC supply and uses a wired remote controller with a 10 m cable. This allows the operator to initiate racking operations from a greater distance from the switchgear, helping reduce personnel exposure during circuit-breaker insertion and withdrawal procedures.

Designed specifically for the SACE Emax 2 platform, the RRD incorporates dedicated controls and position indication for straightforward operation. It is intended to rack a compatible circuit breaker only when the breaker is open and its closing springs are discharged. A separate ABB fixing kit, order code 1SDA085530R1, is required for installation on each compatible E2.2–E6.2 circuit breaker.

Key Advantages

Remote Circuit-Breaker Racking for Safer Switchgear Operation

Racking a withdrawable air circuit breaker involves mechanically moving the breaker between disconnected, test and connected positions. The ABB RRD motorises this operation and places the operator controls at the end of a 10 m cable, allowing the racking sequence to be controlled away from the immediate front of the switchgear.

For correct operation, the compatible Emax 2 circuit breaker must be in the open position with its closing springs discharged. The dedicated fixing kit mechanically interfaces the RRD with the breaker racking system, while the remote controller provides the operating commands and position indication needed to perform the racking procedure.

Typical Applications

• Remote racking of ABB SACE Emax 2 withdrawable air circuit breakers.
• Industrial low-voltage switchboards.
• Power distribution centres and substations.
• Data centre electrical distribution systems.
• Manufacturing and process plant switchgear.
• Utility and infrastructure power distribution.
• Critical facilities using withdrawable Emax 2 breakers.
• Maintenance procedures requiring operation away from the immediate switchgear front.
