Why Choose the ABB Key Lock Open Position with Different Keys E1-E6?
The ABB KEY LOCK OPEN POS. DIFF. KEYS E1/6, order code 1SDA058271R1, is a mechanical locking accessory for compatible ABB SACE Emax E1-E6 air circuit breakers. It is designed to lock a circuit breaker in the open position, helping prevent unintended or unauthorised closing while the locking condition is active.
This version uses a different-key arrangement and is specified for an individual circuit breaker rather than groups of breakers operated with the same key. This makes it suitable for installations where separate breakers require independently controlled key-lock access.
As a dedicated SACE Emax mechanical accessory, the lock integrates with compatible E1 through E6 circuit breakers and supports controlled switching, maintenance isolation and operational interlocking procedures without requiring an electrical control supply.
Key Advantages
- Genuine ABB SACE Emax mechanical accessory.
- Locks a compatible circuit breaker in the open position.

- Helps prevent unintended or unauthorised breaker closing.
- Supports maintenance isolation and controlled operating procedures.
- Purely mechanical locking function requiring no electrical control supply.
Key Features
- Open-position key lock.
- ABB designation: KEY LOCK OPEN POS. DIFF. KEYS E1/6 new.
- Key arrangement: Different keys.
- Intended for one circuit breaker with an individual key.
- Compatible breaker range: SACE Emax E1-E6.
- Mechanical circuit-breaker locking accessory.
- Designed for low-voltage switchgear operating and isolation procedures.
Independent Open-Position Locking for SACE Emax Breakers
Open-position key locking provides a mechanical means of keeping a circuit breaker open until an authorised operator releases the lock. This can form part of switchboard operating procedures where positive control of breaker closing is required during maintenance, isolation or defined switching sequences.
The ABB 1SDA058271R1 is the different-key version for compatible E1-E6 breakers, making it particularly useful where multiple circuit breakers need independent key control rather than a common-key arrangement. Correct implementation can support clear segregation of breaker operating authority within complex low-voltage distribution systems.
Typical Applications
- ABB SACE Emax E1-E6 air circuit breakers.
- Individual circuit-breaker open-position locking.
- Switchboard maintenance and isolation procedures.
- Installations requiring different keys for separate breakers.
- Controlled switching and mechanical interlocking arrangements.
- Industrial, commercial and infrastructure low-voltage switchgear.
