English Translation of Title:
Auxiliary Contact for Water Jet Cutting Machine Parts – Model No. 72155033-Auxiliary-Contact-part.1245.3-1

Introduction, Application, Features, and Maintenance:

This component is an auxiliary contact designed for water jet cutting systems. It is an electrical switching device that is mechanically linked to a main contactor or relay, providing additional normally open (NO) or normally closed (NC) contacts for control, monitoring, or interlocking functions.

Application:
Used in the electrical control panel of water jet cutting machines to provide supplementary switching capability. Typical applications include status indication, alarm circuits, interlock systems, PLC (Programmable Logic Controller) inputs, and remote monitoring of contactor or relay states.

Features:

• Provides additional contacts (NO/NC) for control and monitoring functions.

• Mechanically linked to the main switching device for synchronized operation.

• Manufactured from durable, electrically insulating materials with silver-alloy contacts for reliable performance.

• Compact design for easy installation in control panels.

• Suitable for AC and DC control circuits.

• Designed for long electrical and mechanical life.

Maintenance:

• Regularly inspect the auxiliary contact for signs of wear, arcing, or damage.

• Check electrical connections for tightness and signs of corrosion.

• Verify that the contact operates correctly with the main device (proper NO/NC switching).

• Replace the auxiliary contact immediately if contacts are pitted, welded, or if switching failure is observed.

• Keep the contact area clean and free from dust or debris.

• Follow the manufacturer’s recommended maintenance schedule for contact inspection and replacement.
