Eaton C25BNB240A 2-pole 40 A 120 V AC contactor
A 2-pole, 40 A inductive / 50 A resistive contactor with a 120 V AC coil for 50/60 Hz non-reversing motor and heating control
- Definite-purpose magnetic contactor for heavy-duty industrial power control
- 2-pole non-reversing design handles 40 A inductive and 50 A resistive loads
- 120 V AC coil operates at 50/60 Hz for HVAC and manufacturing automation
- Auxiliary contact capacity of 0 simplifies wiring in single-direction applications
- Rated for 120 V and 240 V AC single-phase motor loads
Definite Purpose Magnetic Contactor
The Eaton C25BNB240A is a non-reversing definite purpose magnetic contactor designed to control power flow in heavy-duty industrial applications. It operates on a 120V AC coil at 50/60 Hz and is built for professionals managing machinery automation in sectors such as HVAC and manufacturing.
Suited for single-phase motor and heating control
This contactor suits installers needing a 2-pole device rated for 40 A inductive and 50 A resistive loads at 120V AC. It is not for applications requiring auxiliary contacts, reversing operation, or three-phase power switching.
40 A inductive and 50 A resistive capacity
The unit comfortably handles single-phase inductive loads up to 40 A and resistive loads up to 50 A at 120V AC. Headroom ends at those ratings; higher current or multi-phase demands require a different device.

Questions about this item
What coil voltage must my control circuit supply for the C25BNB240A to operate?
The contactor coil is rated for 120 V AC at 50/60 Hz, so the control circuit must provide that voltage and frequency.
Can I use this 2-pole contactor with a single-phase motor load at 240 V AC?
Yes, the unit is rated for single-phase horsepower at 240 V AC and handles up to 40 A inductive or 50 A resistive full-load current.
How can I verify the contactor is switching correctly after wiring it?
Apply 120 V AC to the coil and confirm the main contacts close, then measure continuity across the power poles while the coil remains energised.
