Apator RAB 1/2 OHY 125J12 Door Operating Mechanism with Interlock for RA 400/630

The Apator RAB 1/2 OHY 125J12 is a professional door operating mechanism engineered for seamless integration with RA 400 and RA 630 series switch disconnectors. This robust component is designed to provide reliable mechanical control over electrical switchgear, featuring a high-visibility red-yellow handle that serves as a clear visual indicator for emergency or safety-critical operations. With its integrated safety interlock, the mechanism prevents the electrical cabinet door from being opened while the switch is in the 'ON' position, significantly enhancing workplace safety and preventing accidental contact with live components.

Advantages

This operating mechanism offers exceptional durability and precision, ensuring consistent performance in demanding industrial environments. The inclusion of a safety interlock is a critical feature that protects personnel by enforcing proper switching sequences. Its ergonomic design allows for intuitive handling, while the high-contrast color scheme ensures quick identification during maintenance or emergency procedures. The construction is specifically optimized for compatibility with Apator RA series disconnectors, ensuring a perfect fit and reliable mechanical linkage.

Suitable for

• Industrial power distribution cabinets
• Electrical switchgear assemblies
• Control panels requiring safety interlocks
• Maintenance and emergency shutdown systems

When it may not be suitable

This mechanism is specifically designed for use with Apator RA 400 and RA 630 series switch disconnectors. It is not compatible with other switch series or different manufacturers' equipment. It is also not intended for outdoor environments without appropriate protective enclosures to prevent environmental degradation.

Key specifications

• Compatibility: RA 400 and RA 630 series switch disconnectors
• Handle color: Red-Yellow
• Safety feature: Integrated door interlock
• Application: Door-mounted operation

How to use

The mechanism should be mounted on the front door of the electrical cabinet, aligned precisely with the switch disconnector shaft inside. Installation requires ensuring that the interlock linkage is correctly engaged so that the door remains locked when the switch is energized. Once installed, the handle is rotated to toggle the switch state. Regular inspection of the linkage and the interlock mechanism is recommended to ensure smooth operation and continued safety compliance.

What to consider before purchase

• Verify the model of your existing switch disconnector matches the RA 400 or RA 630 series.
• Ensure the cabinet door thickness is compatible with the shaft length provided.
• Confirm that the installation space allows for the full rotation of the handle.

Usage recommendations

Always verify that the switch is in the 'OFF' position before attempting to open the cabinet door, even when the interlock is installed. Perform periodic functional tests of the interlock system to ensure it remains in optimal working condition.
