Applications This floor/base mounted contact module is ideal for applications where mounting from below or at the base level is preferred over front plate mounting. Commonly used in control panels, machinery bases, and applications where access from the rear or bottom is more convenient. The normally open configuration makes it suitable for start functions, enabling circuits, and general switching applications.

Mounting & Installation

• Floor/base mounting design - mounts from below or at base level
• Snap-on concept allows one-hand installation
• No special tools required for assembly
• Compatible with SIRIUS ACT command and signaling devices
• Alternative mounting option to standard front plate mounting

Floor/Base Mounting Benefits

• Rear access installation: Ideal when front panel space is limited
• Protected mounting: Contact module is less exposed than front-mounted variants
• Space efficient: Allows for more compact front panel designs
• Maintenance accessibility: Easy access from behind or below the panel
• Flexible panel design: Enables creative control panel layouts
• Reduced front panel complexity: Keeps the operator interface clean and simple

Screw Terminal Advantages

• Secure connections: Reliable mechanical connection for industrial environments
• High current capacity: Suitable for demanding electrical loads
• Easy maintenance: Standard screwdriver access for connection changes
• Vibration resistant: Mechanical screw connection withstands industrial vibrations
• Wide wire compatibility: Accommodates various wire types and gauges
