Why Choose the ABB MOL-S T4-T5 Key Lock Equal N.20005?

The ABB MOL-S T4-T5 Key Lock Equal N.20005, order code 1SDA054905R1, is a mechanical key-lock accessory for motor-operated ABB SACE Tmax T4 and T5 circuit breakers. Designed for use with the motor operator, it provides a practical locking solution for installations where controlled operation of circuit breakers is required.

The MOL-S configuration uses the same key code N.20005 and is intended for key locking across multiple compatible T4-T5 circuit breakers. Using an equal-key arrangement allows compatible locks within the same key group to be operated with the corresponding common key, simplifying key management in switchboards containing multiple circuit breakers.

Designed specifically for the ABB SACE Tmax T4 and T5 families, the 1SDA054905R1 is classified as a mechanical locking accessory rather than a circuit breaker or replacement protection component. It is intended for compatible motor-operated circuit breaker configurations and forms part of ABB's range of Tmax operating and safety accessories.

Equal-Key Locking for Motor-Operated Circuit Breakers

Key-lock accessories provide a mechanical means of controlling access to circuit breaker operation. The ABB MOL-S arrangement is designed for compatible Tmax T4 and T5 motor operators and uses an equal-key system, allowing multiple appropriately configured locks to share the same key code.

The N.20005 designation identifies the equal-key group for this accessory. This can be particularly useful in switchboards containing several compatible motor-operated circuit breakers where a common locking key is preferred instead of maintaining a different key for every device.

Typical Applications

  • ABB SACE Tmax T4 motor-operated circuit breakers.
  • ABB SACE Tmax T5 motor-operated circuit breakers.
  • Industrial low-voltage distribution switchboards.
  • Commercial electrical distribution panels.
  • Motor control and automation switchboards.
  • Manufacturing and process plant electrical systems.
  • Installations requiring controlled circuit breaker operation.
  • Multiple compatible circuit breakers requiring a common key code.
