1SDA073819R1 ABB KLP-A Pos.lock RoProKirk E2.2…E6.2 2Key

Why Choose the ABB KLP-A RoProKirk E2.2...E6.2 2nd Key Position Lock?

The ABB KLP-A RoProKirk E2.2...E6.2 2nd Key, order code 1SDA073819R1, is a mechanical key-lock accessory for ABB SACE Emax 2 air circuit breakers. Designed for E2.2, E4.2 and E6.2 frames, it forms part of the KLP position-locking system used to control the racking position of withdrawable Emax 2 circuit breakers.

The KLP-A system provides keyed mechanical locking for the racked-in, test and racked-out positions, helping prevent unauthorised or incorrect movement of a withdrawable breaker between operating positions. This version uses the RoProKirk key-lock arrangement and is specifically identified as the second-key configuration.

Mechanical position interlocking is particularly valuable in switchboards where defined operating sequences and controlled access are required. ABB specifies the second-key version for applications where the corresponding PLP position padlock arrangement is already present, helping integrate the breaker into a coordinated mechanical safety and interlocking scheme.

Mechanical Position Interlocking for Emax 2 Switchgear

Withdrawable air circuit breakers can occupy distinct connected, test and disconnected positions within their fixed parts. A mechanical key-lock system can restrict movement between these positions until the appropriate key and operating sequence are available, helping operators maintain controlled switchgear procedures and coordinated interlocking arrangements.

The ABB 1SDA073819R1 KLP-A is the RoProKirk second-key version for Emax 2 E2.2 through E6.2 frames. It is designed for applications requiring keyed control of breaker racking positions and can form part of wider mechanical interlocking schemes used in industrial, infrastructure and critical-power switchboards.

Typical Applications

• ABB SACE Emax 2 withdrawable air circuit breakers.
• Low-voltage main distribution switchboards.
• Mechanical breaker-position interlocking systems.
• Industrial power distribution switchgear.
• Generator and standby power switchboards.
• Data centres and critical power installations.
• Switchboards requiring controlled racking sequences.
• Installations using RoProKirk mechanical key interlocking.
