Eaton C25CNB125A Definite Purpose Magnetic Contactor 120V AC 1 Pole
A definite-purpose magnetic contactor rated 25 A inductive, 35 A resistive and 30 A LED at 120 V AC coil voltage
- Handles 25 A inductive loads with 120 V AC coil
- 30 A LED lighting rating for solid-state drivers
- 35 A resistive capacity for heating elements
- Single-pole C-frame design fits tight panels
- 2 hp at 120 V and 3 hp at 240 V single-phase
What this contactor does
The Eaton C25CNB125A is a definite purpose magnetic contactor built for single phase motor and lighting control. It switches 120 V AC coil voltage and carries a 1 pole configuration rated for 2 hp at 120 V AC or 3 hp at 240 V AC. The frame size C design suits HVAC, compressor and general purpose switching where a compact non reversing contactor is required.
What to verify before ordering
Confirm the control circuit supplies 110 to 120 V AC to match the coil rating. Ensure the load does not exceed 25 A inductive or 35 A resistive full load current and that the application is single phase non reversing. The unit ships with no enclosure so plan for suitable panel or cabinet mounting and verify local code compliance for open frame devices.
Thermals noise and power in use
The contactor operates quietly with a standard AC coil hum typical for 120 V control circuits. Heat rise stays within definite purpose limits when running at or below the 25 A inductive rating. Power draw is limited to the coil consumption only and the open frame design allows free airflow for natural cooling during continuous duty cycles.

Questions about this item
Does the Eaton C25CNB125A contactor ship with any wiring accessories or mounting hardware, or must those be purchased separately?
The unit is supplied as the contactor only; mounting hardware, wiring terminals and any required enclosures are not included and must be sourced separately.
Which coil voltage version should be selected for a 120 V AC control circuit?
Choose the 110-120 V AC coil version; it is the only coil rating offered for this model and matches a standard 120 V AC control supply.
What does the 25 A inductive full-load current rating mean when the contactor is controlling a motor load?
It indicates the maximum continuous inductive current the contacts can carry in a motor circuit, corresponding to 2 hp at 120 V AC single-phase or 3 hp at 240 V AC single-phase.
