1SDA066629R1 ABB MOL-D XT2-XT4 Ronis Different-Key Motor Operator Lock

Why Choose the ABB 1SDA066629R1 MOL-D XT2-XT4 Ronis Key Lock?

The ABB 1SDA066629R1 is a MOL-D Ronis key lock designed for the motor operator of ABB SACE Tmax XT moulded-case circuit breakers. Specifically intended for XT2 and XT4, it provides mechanical locking of the motor operator in the open position, supporting controlled isolation and helping prevent unintended circuit-breaker operation.

The MOL-D configuration uses different Ronis keys, making it suitable where individual motor-operated circuit breakers require separate key control rather than a common-key arrangement. It is designed for one circuit breaker, providing a dedicated locking solution for the associated XT2 or XT4 motor operator.

As part of the ABB T-Max XT 250 Range, the 1SDA066629R1 is purpose-designed for compatibility with the Tmax XT accessory platform. It provides a practical mechanical security solution for switchboards, machinery panels and low-voltage distribution systems using motor-operated XT2 or XT4 circuit breakers.

Secure Motor-Operator Isolation

A motor-operator key lock provides mechanical control over electrically operated circuit breakers by restricting operation while the associated mechanism is locked. Open-position locking is particularly useful during maintenance and isolation procedures where unintended operation of the circuit breaker must be prevented.

The ABB MOL-D configuration uses different Ronis keys, allowing individual locking control for the associated circuit breaker. Designed specifically for XT2 and XT4 motor operators, the 1SDA066629R1 provides a purpose-built solution for secure breaker management in industrial and commercial electrical installations.

Typical Applications

• ABB SACE Tmax XT2 and XT4 circuit breakers with motor operators.
• Industrial electrical distribution boards.
• Motor-operated circuit-breaker isolation.
• Maintenance and servicing procedures.
• Industrial machinery and control panels.
• Switchgear requiring individual key-controlled locking.
• Commercial and industrial low-voltage distribution systems.
