Schneider Electric ZB5AG6 Key Switch, 2-Position, Key 455, Left Spring Return

The Schneider Electric ZB5AG6 is a professional-grade 2-position key-operated selector switch from the Harmony XB5 series. Designed for integration into industrial control panels, this unit provides a secure method for managing electrical circuits. It features a specific key 455 mechanism and a spring return from the left position, which automatically resets the switch to its default state, enhancing operational safety and control precision in automation systems.

Advantages

This selector switch is engineered for durability and reliability in demanding industrial environments. The key-operated design prevents unauthorized access or accidental activation, ensuring that only personnel with the correct key can operate the machinery. Its robust construction and ergonomic design allow for seamless integration into standard 22 mm mounting holes, making it a versatile choice for modern control panels that require high-performance switching components.

Suitable for

• Industrial automation control panels
• Machine safety and emergency control systems
• Access control for electrical equipment
• Process control and monitoring stations

When it may not be suitable

This switch is not intended for outdoor environments without appropriate protective enclosures, as it is designed for panel-mounted indoor applications. It is also not suitable for high-current direct switching without an appropriate contact block, as it functions primarily as an operator interface for control circuits.

Key specifications

• Type: 2-position key-operated selector switch
• Key model: 455
• Operation: Spring return from left
• Mounting diameter: 22 mm
• Series: Harmony XB5

How to use

To install the switch, insert the operator head into a standard 22 mm panel cutout and secure it using the provided locking nut. Once mounted, attach the necessary contact blocks to the rear of the operator. To operate, insert the key 455 into the lock and turn it to the desired position. The spring return mechanism will automatically return the switch from the left position once the key is released, ensuring the system returns to its designated standby state.

What to consider before purchase

• Verify that the 22 mm mounting hole is compatible with your existing panel layout.
• Ensure that the key 455 mechanism meets your specific security and access requirements.
• Confirm that the spring return functionality aligns with your control logic.
• Check if additional contact blocks are required for your specific electrical configuration.

Usage recommendations

Regularly inspect the key mechanism for debris and ensure the switch operates smoothly. Only use the specified key 455 to prevent damage to the internal locking cylinder.
