Miniature Contactor Accessories

Miniature contactors save panel space in control circuits, small motor starters and HVAC equipment. Accessories add functions to these compact contactors without moving up to a larger frame, making it easy to add signaling, interlocking or surge protection where you need it.

Common Accessories

• Auxiliary contact blocks – front or side-mount contacts for status and interlocking
• Surge suppressors – RC, varistor and diode modules that protect control electronics
• Mechanical interlocks – for reversing and transfer applications
• Overload relays – sized to mount directly to miniature contactors
• Marking tags and covers – for clear identification and finger-safe wiring

Choosing Accessories

Accessories are usually brand- and series-specific, so start with the contactor model number. Check how many auxiliary contacts the contactor will accept and whether they mount on the front or side. For coils switched by PLC outputs, adding a suppressor extends output life and reduces electrical noise.

Centro can match accessories to the miniature contactors already in your panels. Send us the part number and we'll confirm compatibility.
