1SDA038351R1 ABB Padlock Device in Open Position 4 mm E1–E6

Why Choose the ABB 1SDA038351R1 Padlock Device?

The ABB 1SDA038351R1 is a padlock device for locking a compatible circuit breaker in the open position. Part of the ABB New Emax accessory range, it provides a mechanical means of securing the breaker against closing when isolation must be maintained during servicing, inspection or other controlled electrical work.

The device is designed for use with a 4 mm diameter padlock shackle. Once fitted and secured with a suitable padlock, the accessory helps prevent operation of the circuit breaker from the open position, providing a clear physical locking measure as part of an appropriate electrical isolation procedure.

Designed for compatible ABB E1–E6 SACE Emax circuit breakers, the 1SDA038351R1 is suitable for industrial and commercial switchboards where controlled access and secure breaker isolation are required. Its dedicated ABB design provides a purpose-made locking solution for compatible New Emax equipment.

• ABB order code 1SDA038351R1.

Secure Open-Position Circuit-Breaker Locking

Open-position locking provides a physical means of keeping a circuit breaker from being closed while maintenance, inspection or other work is being carried out. When the ABB 1SDA038351R1 is engaged and secured using a suitable 4 mm shackle padlock, the breaker is mechanically restrained in its open state until the locking arrangement is deliberately removed.

This functionality is particularly useful in switchboards where circuit-breaker operation must be controlled as part of an established isolation procedure. The padlock device adds a mechanical barrier against unintended closing, complementing the site's applicable safety procedures and electrical isolation practices.

Typical Applications

• Open-position locking of compatible ABB SACE Emax circuit breakers.
• Industrial low-voltage distribution switchboards.
• Commercial electrical distribution systems.
• Maintenance and servicing isolation procedures.
• Electrical plant rooms and controlled-access switchgear.
• Applications requiring mechanical prevention of circuit-breaker closing.
