Why Choose the ABB 1SDA073844R1 SLE External Shutter Lock?
The ABB 1SDA073844R1 is an SLE external shutter lock designed specifically for the ABB Emax 2 E6.2 air circuit breaker platform. It provides mechanical padlocking of the safety shutters associated with the withdrawable breaker installation, helping restrict access to the fixed-part power contacts when the circuit breaker is removed.
The SLE accessory is designed to accept padlocks with 4 mm, 6 mm or 8 mm shackle diameters. By allowing the shutters to be mechanically secured, it supports controlled maintenance and isolation procedures in low-voltage switchgear equipped with withdrawable Emax 2 E6.2 circuit breakers.
ABB specifies the 1SDA073844R1 as SLE Bl. shutter lock D=4/6/8mm E6.2. It is a dedicated mechanical locking accessory for the E6.2 frame and is intended for applications where external padlock control of the fixed-part shutters is required.

Mechanical Shutter Locking for Withdrawable Emax 2 Switchgear
The safety shutters in a withdrawable air circuit breaker installation provide a physical barrier over the fixed-part power contacts when the moving circuit breaker is withdrawn. Mechanically locking these shutters can provide an additional means of controlling access during maintenance, inspection and other switchgear procedures.
The ABB 1SDA073844R1 provides an external SLE shutter-locking arrangement for the Emax 2 E6.2. Its compatibility with 4 mm, 6 mm and 8 mm padlock shackles allows the shutters to be mechanically secured as part of an appropriate switchgear isolation and access-control procedure.
Typical Applications
- ABB Emax 2 E6.2 withdrawable air circuit breaker installations.
- External locking of fixed-part safety shutters.
- Industrial low-voltage switchboards.
- Power distribution and protection systems.
- Maintenance and switchgear isolation procedures.
- Applications requiring padlock-controlled access to withdrawable breaker fixed-part contacts.
