1SDA058279R1 ABB E1-E6 N.20008 Key Lock and 4 mm Padlock Accessory

Why Choose the ABB E1–E6 N.20008 Key Lock and 4 mm Padlock Accessory?

The ABB 1SDA058279R1 is a key lock and 4 mm padlock accessory for compatible ABB SACE Emax E1–E6 air circuit breakers. ABB identifies the accessory as KEY-PADL.DE.4mm CON-ISOL.N.20008 E1/6new, providing mechanical locking of the circuit breaker in the connected, test and isolated/racked-out positions.

This version uses same-key N.20008 locking, making it suitable for groups of circuit breakers that need to be operated with the same key reference. It combines the N.20008 key-lock arrangement with provision for 4 mm diameter padlocks, providing controlled mechanical locking for withdrawable Emax circuit-breaker installations.

Designed for compatible E1, E2, E3, E4 and E6 SACE Emax frames, the 1SDA058279R1 is an IEC mechanical accessory intended to help prevent unintended movement of a withdrawable breaker between its racked-in, test and racked-out positions during operation, isolation and maintenance.

Key Advantages

• Provides key and padlock locking for compatible ABB SACE Emax circuit breakers.
• N.20008 same-key configuration supports groups of breakers operated with a common key reference.

Reliable Position Locking for Withdrawable SACE Emax Breakers

Withdrawable air circuit breakers can occupy defined positions within their fixed part, including connected or racked-in, test and isolated or racked-out positions. Mechanical locking helps control movement between these positions and can form part of an organised isolation and maintenance procedure by preventing unintended repositioning while the locking arrangement is engaged.

The ABB 1SDA058279R1 combines N.20008 same-key operation with 4 mm padlock provision. This makes it particularly useful where groups of compatible SACE Emax breakers require a common key reference while retaining the ability to apply padlocks for controlled breaker-position locking.

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.
• Withdrawable low-voltage distribution switchboards.
• Industrial electrical isolation arrangements.
• Groups of breakers requiring N.20008 same-key locking.
• Maintenance and controlled-access power-distribution systems.
