Why Choose the ABB 1SDA043466R1 Mechanical Interlock Accessory?
The ABB 1SDA043466R1 is a genuine mechanical interlock accessory designed specifically for compatible ABB SACE Emax circuit breakers. It is configured for E4 four-pole and E6 three-pole breakers and provides the breaker-mounted mechanism required when incorporating these frame and pole combinations into a mechanical interlocking system.
Mechanical interlocking is used to coordinate the operating states of multiple circuit breakers and physically restrict prohibited switching combinations. The 1SDA043466R1 provides the appropriate interlock mechanism for the moving part of withdrawable E4 four-pole and E6 three-pole breakers, allowing them to interface with the corresponding ABB interlock cable arrangement.
As part of the ABB Accessories for Emax range, the 1SDA043466R1 is purpose-designed for SACE Emax switchgear and can be combined with the appropriate ABB cables and associated interlock components to create a complete mechanical interlocking system for source transfer, bus-tie and other controlled power-distribution applications.

Purpose-Designed Interlocking for E4 and E6 Circuit Breakers
A mechanical circuit-breaker interlock provides a direct physical relationship between interconnected breakers, helping ensure that operating combinations prohibited by the switchboard design cannot be selected. The breaker-mounted mechanism transfers the breaker operating state to the associated cable interlocking system.
The ABB 1SDA043466R1 provides this function for the specific mechanical arrangements of E4 four-pole and E6 three-pole SACE Emax breakers. When used with the appropriate ABB interlock cables and associated components, it supports dependable mechanical coordination in multi-breaker power-distribution systems.
Typical Applications
- Mechanical interlocking of ABB SACE Emax circuit breakers.
- E4 four-pole circuit-breaker installations.
- E6 three-pole circuit-breaker installations.
- Industrial low-voltage distribution switchboards.
- Source-changeover and transfer systems.
- Bus-tie and bus-coupler arrangements.
- Multi-source power-distribution systems.
