Reliable Auxiliary Contact Mounting for ABB Switchgear

Mounting frames such as the ABB OSZ4 are used to provide the mechanical interface required for fitting auxiliary contact accessories to compatible switching devices. Once installed, auxiliary contacts can provide electrical feedback from the main switch to indicator lamps, relays, PLC inputs or automation systems.

The OSZ4 is particularly useful where switch status monitoring is required in industrial control panels. By supporting auxiliary contact integration, it helps improve visibility of switch position and enables more organised control, indication and interlocking circuit design.

Typical Applications

• Industrial control panels and switchgear assemblies.
• Auxiliary contact mounting on compatible ABB switches.
• Remote switch position indication.
• PLC and automation system feedback.
• Electrical interlocking circuits.
• Machine control and monitoring systems.
• Compatible ABB OS disconnect switch and switch fuse installations.
