Why Choose the ABB 1SDA073849R1 Emax 2 DLP Door Opening Lock?
The ABB 1SDA073849R1 is a DLP mechanical door opening lock accessory designed for ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breaker installations. Identified by ABB as DLP E2.2...E6.2, it is specifically designed to prevent the switchgear door from being opened when a compatible withdrawable circuit breaker is in the racked-in or test position.
As part of the ABB SACE Emax 2 mechanical accessory range, the DLP provides a direct mechanical relationship between the circuit breaker position and access to the switchgear compartment. This helps ensure that compartment access follows the intended operating sequence and prevents the door from being opened while the breaker is in positions where access should be restricted.
The 1SDA073849R1 is suitable for Emax 2 E2.2, E4.2 and E6.2 withdrawable circuit breaker installations and is supplied as a loose accessory. Its mechanical operation requires no electrical control supply, making it a practical solution for switchboards requiring dependable position-dependent door interlocking.

Position-Dependent Door Interlocking for Emax 2 Switchgear
Withdrawable Emax 2 circuit breakers can occupy different positions within their fixed part, including connected, test and disconnected states. The DLP mechanical interlock is designed to prevent the switchgear door from being opened when the circuit breaker is racked-in or in the test position, helping ensure that compartment access is coordinated with the breaker position.
The ABB 1SDA073849R1 provides this mechanical door interlocking function for Emax 2 E2.2, E4.2 and E6.2 installations. Because the interlock operates mechanically, its function does not depend on auxiliary power or electronic control logic, making it suitable for switchboards where reliable physical access control is required as part of defined operating and maintenance procedures.
Typical Applications
- ABB SACE Emax 2 E2.2, E4.2 and E6.2 withdrawable air circuit breakers.
- Switchgear compartment door interlocking.
- Racked-in and test-position access control.
- Low-voltage switchboards and power distribution assemblies.
- Controlled switching, isolation and maintenance procedures.
- Industrial, commercial and infrastructure power distribution systems.
