Why Choose the ABB 1SDA074283R1 2500 A L OFF Rating Plug?
The ABB 1SDA074283R1 is a 2500 A L OFF rating plug designed for compatible ABB SACE Emax 2 air circuit breakers. Identified by ABB as RATING PLUG 2500 L OFF E2.2..E6.2 INST, it provides a 2500 A current reference for compatible Emax 2 E2.2, E4.2 and E6.2 protection configurations.
The L OFF configuration is intended for applications where the long-time overload protection function is disabled. This specialised arrangement supports engineered protection schemes in which overload protection is provided separately or where long-time protection from the circuit-breaker trip unit is intentionally not required.
The INST designation identifies this version as an installed configuration for the compatible Emax 2 circuit breaker. Combining a high 2500 A rating with ABB's modular Emax 2 protection architecture, the 1SDA074283R1 is suited to demanding low-voltage power-distribution installations.

2500 A L OFF Protection Configuration for Emax 2
ABB rating plugs form part of the configurable electronic protection architecture used with SACE Emax 2 air circuit breakers. The rating plug establishes the applicable current reference for the compatible protection system, enabling the circuit breaker to be configured for the required installation characteristics.
The ABB 1SDA074283R1 combines a 2500 A current reference with an L OFF configuration for compatible E2.2, E4.2 and E6.2 circuit breakers. It is particularly suited to engineered systems where the long-time overload function is intentionally disabled and overload protection is addressed elsewhere in the overall electrical protection scheme.
Typical Applications
- ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breakers.
- Applications requiring a 2500 A L OFF protection configuration.
- Systems with separately implemented overload protection.
- Industrial low-voltage main distribution switchboards.
- Infrastructure and critical power distribution systems.
- OEM and factory-configured switchgear assemblies.
