Choosing between contactors in relays, contactors, and industrial switches usually comes down to how many circuits you need to switch and what control voltage your system uses. Here, the 4 Pole 60A NC Contactor with a 24V coil faces a 1 Pole 40 Amp 24 VAC Coil AC Contactor designed as a direct replacement for AC motor applications. The price difference is $80.29, with the lower-priced unit at $19.66 and the higher-priced unit at $99.95, so the right choice depends on the job, not just the cost.
Quick verdict
If you need a panel-mounted setup with several switched circuits, the 4 Pole 60A NC Contactor is the stronger pick. If you are replacing a contactor in an air conditioner compressor or condenser unit, the 1 Pole 40 Amp 24 VAC Coil AC Contactor delivers the coil voltage you need for a straightforward swap.
Comparison
| Feature | 4 Pole 60A NC Contactor | 1 Pole 40A 24V Contactor |

Where each product wins
The 4 Pole 60A NC Contactor wins when the installation has several circuits to switch, especially in motor and lighting applications. Its normally closed configuration and silent coil operation make it suitable for HVAC and industrial panels that need dependable switching with low hum.
The 1 Pole 40 Amp 24 VAC Coil AC Contactor wins for direct, straightforward replacement work. Its 40 Amp FLA rating and 24 VAC coil match common contactor specs, and the copper terminals and pure copper coil support good conductivity.
Product notes
4 Pole 60A NC Contactor 24V Coil IEC 400V for Motor & Lighting DIN Rail Mount
This contactor is designed for installations that need more than one switched circuit. The DIN rail mount and included mounting base make it easy to place in an industrial panel, and the normally closed action means the contacts stay closed until the coil is energized. That behavior is useful in motor and lighting loads where you want a closed-at-rest state. For installations that need enough switching capacity for several loads and a permanent panel mount, this is the one to pick. The limitation is that its normally closed design will not behave like a normally open contactor, so make sure that matches your circuit's behavior.
1 Pole 40 Amp 24 VAC Coil AC Contactor
This single-pole unit is built for simple, direct swaps. Copper terminal contacts and a pure copper coil support conductivity, and the 40 Amp FLA rating is a common specification for this type of contactor. It is a direct replacement that does not require wiring or adapter changes. Reach for it when you want a no-fuss replacement for a single-pole AC contactor. The limitation is the pole count: with only one pole, it cannot switch multiple circuits at once, so a multi-circuit motor or lighting load will need additional contactors.
Final choice by use case
Choose the 4 Pole 60A NC Contactor for a panel or HVAC installation that calls for expanded control. Choose the 1 Pole 40 Amp 24 VAC Coil AC Contactor when you want a straightforward contactor replacement without extra switching capacity. The 1 Pole 40 Amp 24 VAC Coil AC Contactor keeps the repair simple; the 4 Pole 60A NC Contactor gives you more switching capacity.
