Why Choose the ABB KLC-S Key Lock Open N.20007 E1.2?

The ABB KLC-S Key Lock Open N.20007 E1.2, order code 1SDA073785R1, is a mechanical key-locking accessory designed specifically for the ABB SACE Emax 2 E1.2 air circuit-breaker frame. It forms part of ABB's KLC range of key locks for securing a circuit breaker in the open position.

The KLC-S mechanism helps prevent unauthorised or unintended closing of the circuit breaker by mechanically locking it in the open state. This provides an important additional control measure for switchgear maintenance, operating procedures and installations where controlled access to breaker operation is required.

This KLC-S version uses key number 20007 and is intended for applications where an equal-key arrangement is required between compatible circuit breakers. Purpose-designed for the Emax 2 platform, the 1SDA073785R1 provides a manufacturer-engineered mechanical locking solution for dependable low-voltage switchgear operation.

Secure Open-Position Circuit Breaker Locking

Open-position key locking provides a mechanical means of preventing a circuit breaker from being closed until the appropriate key-locking procedure has been completed. This can be used to support controlled switching sequences, maintenance procedures and operational interlocking arrangements without relying on an electrical control supply.

The ABB 1SDA073785R1 combines this mechanical locking function with a defined number 20007 key configuration. Its equal-key arrangement can be used where compatible E1.2 circuit breakers need to share the same key coding, helping simplify controlled access across suitable switchgear installations.

Typical Applications

  • ABB SACE Emax 2 E1.2 air circuit breakers.
  • Circuit-breaker open-position locking.
  • Controlled switchgear maintenance procedures.
  • Industrial low-voltage distribution switchboards.
  • Mechanical access and operating-control schemes.
  • Installations requiring equal-key locking between compatible breakers.
