1SDA058278R1 ABB E1-E6 Key Lock and 4 mm Padlock with Different Keys

Why Choose the ABB E1–E6 Key Lock and 4 mm Padlock Accessory?

The ABB 1SDA058278R1 is a key lock and 4 mm padlock accessory designed for ABB SACE Emax E1–E6 air circuit breakers. ABB identifies the accessory as KEY-PADL.DE.4mm CON-ISOL.DIF.KEYSE1/6new, providing mechanical locking with different keys for controlling the circuit breaker's connected and isolated positions.

Designed for compatible E1, E2, E3, E4 and E6 SACE Emax circuit breakers, the accessory combines key-operated locking with provision for a 4 mm diameter padlock. It is intended to help prevent unauthorised or unintended changes to the breaker position during operation, isolation and maintenance procedures.

The different-key configuration makes the 1SDA058278R1 suitable where individual locking arrangements are required rather than a common key shared across multiple breakers. As an original ABB Emax accessory, it is designed for mechanical integration with the specified circuit-breaker frames and is supplied as a loose or configurable IEC accessory.

Key Advantages

• Provides key and padlock locking for compatible ABB SACE Emax circuit breakers.

Reliable Mechanical Locking for SACE Emax Circuit Breakers

Mechanical position locking provides an additional means of controlling access to the operating positions of a circuit breaker. By combining a key lock with provision for a padlock, the ABB 1SDA058278R1 can support electrical isolation procedures by helping prevent unintended movement between the permitted breaker positions while the locking arrangement is engaged.

The accessory uses different keys, making it appropriate where individual circuit breakers require separately controlled locking arrangements. Its compatibility across E1–E6 SACE Emax frames provides a consistent locking solution for switchboards incorporating several breaker sizes within the same Emax platform.

Typical Applications

• ABB SACE Emax E1 air circuit breakers.
• ABB SACE Emax E2 and E3 air circuit breakers.
• ABB SACE Emax E4 and E6 air circuit breakers.
• Main low-voltage distribution switchboards.
• Industrial electrical isolation arrangements.
• Switchboards requiring individually keyed breaker locking.
• Maintenance and controlled-access power-distribution systems.
