Whether you want them on or off, this contactor from Eaton keeps the switching operations of your small motors, automated controls and HVAC systems on point. It has interlocked opposing contacts to prevent incorrect actuation and boost electrical safety. The unit is a space-saver that measures only 52 (L) x 45 (W) x 58 (H), so it's a sure fit in crowded installations. A modular design lets you combine it with other units to customise your setup. Weighing in at just 170g, the device puts minimal strain on panels and rails.

• Integrated short-circuit protection blocks rogue currents to help prevent service interruptions
• IP20 rating shows it's finger-safe and shielded against objects larger than 12mm
• Screw terminals secure conductors to reduce accidental disconnection
• Works reliably in temperatures between -25°C and +50°C

It has four poles, so it accommodates multiple circuits to simplify your layout.

You can either fasten it to a panel or enclosure with screws or opt for the tool-free convenience of simply snapping it onto a DIN rail.
