Why Choose the ABB 1SDA073790R1 KLA Ronis Profalux Key Lock?
The ABB 1SDA073790R1 is a KLA Ronis Profalux key-lock arrangement designed for the ABB Emax 2 E1.2 air circuit breaker. It provides the provision required for a Ronis Profalux key-lock system that mechanically prevents the circuit breaker from being closed while the open-position locking condition is active.
Open-position key locking is particularly useful in switchgear installations where maintenance procedures, operating sequences or mechanical interlocking schemes require positive control over when a circuit breaker can be closed. The Ronis Profalux arrangement enables the Emax 2 E1.2 to be incorporated into key-controlled operating procedures without relying solely on electrical control logic.
ABB specifies the 1SDA073790R1 as KLA Key lock open Ronis Profalux E1.2. It is intended for the Emax 2 E1.2 frame and provides the predisposition for a Ronis Profalux open-position key lock, with the applicable key-lock component supplied separately for the locking system.

Mechanical Open-Position Locking for Controlled Switchgear Operation
A key-lock arrangement provides a physical means of maintaining a circuit breaker in the open state when an operating or maintenance procedure requires closing to be prevented. Because the locking condition is mechanical, it can form part of a defined interlocking sequence independently of normal electrical opening and closing commands.
The ABB 1SDA073790R1 provides the Ronis Profalux key-lock predisposition for the Emax 2 E1.2. When completed with the appropriate Ronis locking component, the arrangement can be incorporated into key-controlled switchgear sequences that help ensure the breaker remains open until the required mechanical interlocking conditions have been satisfied.
Typical Applications
- ABB Emax 2 E1.2 air circuit breaker installations.
- Circuit breaker open-position locking.
- Ronis Profalux mechanical key-interlocking systems.
- Industrial low-voltage switchboards.
- Maintenance isolation and controlled operating procedures.
- Power distribution systems requiring key-controlled breaker operation.
