Eaton 120V AC 3-pole contactor, grey industrial housing

Eaton

Eaton C25DND330A 120V AC 3-pole definite-purpose magnetic contactor 30 A inductive 40 A resistive

SKU CH-M784-ZXK3G

Controls power flow in industrial equipment at 120 V AC with 30 A inductive and 40 A resistive ratings

  • Controls inductive loads up to 30 A with 120 V AC coil
  • Handles resistive heating loads up to 40 A at 50/60 Hz
  • Manages up to four auxiliary circuits for flexible automation
  • Three-pole definite-purpose design for non-reversing power control
  • Built by Eaton for HVAC, data-processing and manufacturing equipment

Definite-purpose 3-pole contactor

The Eaton C25DND330A is a definite-purpose magnetic contactor built for industrial power switching in HVAC, data-processing and manufacturing equipment. It handles three power poles in a non-reversing configuration and is sold new for maintenance or original-equipment installation.

120 V AC coil with 30 A inductive / 40 A resistive

The coil operates on 120 V AC at 50/60 Hz. Main contacts are rated for 30 A continuous inductive loads such as motors or transformers and 40 A resistive or heating loads; exceeding either rating can cause overheating or damage.

Panel-mount with up to four auxiliary circuits

The unit mounts in a standard panel cut-out and accepts an auxiliary contact module that adds up to four secondary circuits for control signalling. Verify the coil voltage matches the control supply and that the load type stays within the 30 A inductive or 40 A resistive limits before wiring.

Questions about this item

What does the 30 A inductive rating mean when the contactor is installed in a motor circuit?

It means the contactor can continuously switch motor or transformer loads up to 30 A without overheating.

How does the 120 V AC coil voltage and 50/60 Hz frequency limit the control circuit?

The coil must be driven by a 120 V AC supply at either 50 Hz or 60 Hz; other voltages or frequencies will not operate it reliably.

What panel space and mounting provisions does the C25DND330A need?

The 3-pole definite-purpose frame mounts with standard screws and accepts up to four auxiliary contact modules on the side.
