- Handles resistive loads up to 35 A full load current
- Safe low-voltage operation with 24 V AC coil
- Compact single-pole design for simple panel mounting
Definite Purpose Contactor for Lighting
This Eaton C25CNB125T is a definite purpose magnetic contactor built for switching LED lighting loads. It carries a 30 A LED lighting current rating and a 25 A inductive full load current rating. The single pole design suits circuits that need one switched leg. It is intended for electricians and maintenance teams controlling lighting branches.
DIN Rail Mounting with Screw Terminals
The C25 frame mounts on standard DIN rail and uses screw terminals for line and load connections. Coil voltage is 24V AC, so the control circuit must supply that exact voltage. A common error is applying 120V or 240V to the coil, which will damage the contactor. Verify the control transformer output before wiring.
24V AC Coil Voltage Determines Compatibility
The coil requires a 24V AC source; it will not operate on DC or other AC voltages. If your control panel supplies 120V AC or 24V DC, this contactor is not the correct part. Match the coil voltage to your control circuit to avoid failure.

Questions about this item
How can I verify the contactor is working correctly after wiring it to a 24V AC control circuit?
Apply 24V AC to the coil and listen for the audible click of the contacts closing; then measure continuity across the power poles to confirm the 1-pole circuit is complete.
What components are included with the C25CNB125T and what must be sourced separately?
The contactor itself is supplied; mounting hardware, control wiring, and any required overload protection or enclosure are not included and must be purchased separately.
Which current rating should I select for a resistive load versus an inductive motor load?
For resistive heating loads use the 35 A full-load current rating; for inductive motor loads at 240V AC single-phase use the 25 A inductive rating or the 3 hp motor rating.
