Overview
The Struthers Dunn A275KXX9 is a compact motor reversing contactor from the proven 275-series platform. The 275 series is a 2 coil, compact motor reversing contactor which finds extensive applications in the industrial door operator industry, the hoist industry and electronic wheel balancers, to name a few. This unit is designed for definite-purpose motor reversal control in industrial and commercial applications requiring frequent jogging and precise directional control.
Key Features
- Mechanically interlocked armatures is a standard feature to prevent simultaneous contact closure
- 2x 3PST-NO-DM contact configuration with 15 Amp current rating and silver alloy contact material
- Quick connect coil terminals extending out the back (opposite the contact terminals)
- 2 Auxiliary contacts each SPDT (1 per coil) with .25″ quick connect terminals
- Semi-enclosed enclosure for panel or chassis mounting
- Suitable for industrial door operators, hoists, and wheel balancer equipment
Technical Specifications
The A275KXX9 is available in multiple coil voltage configurations. Verify your specific voltage requirement (24VAC, 24VDC, 48VDC, 120VAC, or 240VAC) before ordering.
