ABB DP30C2P-F – Frequently Asked Questions
1) What coil voltages does the ABB DP Series contactor come in?
Two coil voltages are offered on the ABB DP Series: 24 volt and 120 volt. The 24 volt version is the DP30C2P-F and the 120 volt is the DP60C3P-1. Coil voltage has to match what your control circuit actually puts out, so a 24V thermostat or low voltage control transformer takes the 24V coil, while a line-voltage 120V control circuit takes the 120V coil. Putting a 120V coil on a 24V control circuit will simply not pull the contactor in.
2) What is the difference between the DP30C2P-F and the DP60C3P-1 ABB contactors?
They differ in poles, amperage, and coil voltage. The DP30C2P-F is a 2-pole, 30 amp contactor with a 24 volt coil, typical of a residential or light commercial condensing unit where only the two hot legs are switched. The DP60C3P-1 is a 3-pole, 60 amp contactor with a 120 volt coil, suited to larger three-phase compressors and rooftop units. Pick by the load rating on the equipment nameplate first, then confirm your control voltage.
3) Can I use a DP Series contactor to switch a building lighting panel instead of a lighting contactor?
The ABB DP Series is built for definite purpose load switching on HVAC, refrigeration, food service, and welding equipment, not for multipole lighting control. For a lighting panel, the Square D 8903S Type S electrically held lighting contactor in a 3-pole configuration, or the Square D 8903L Series Type L multipole lighting contactor rated 8-pole, 30A, 600V, is the product built for that duty. Use the DP Series where a compressor, blower motor, or similar equipment load is being switched.
4) What is the closest cross-brand equivalent to an ABB DP Series contactor for an HVAC condensing unit?
The ABB DP Series is a definite purpose electromechanical contactor for HVAC, refrigeration, food service, and welding equipment. The closest cross-brand counterpart is the Square D Class 8910 definite purpose contactor, which serves the same definite purpose switching role. Square D also offers the 8910DP definite purpose contactor in an open construction if the contactor is going inside an existing panel or unit housing rather than its own enclosure. Match amperage, pole count, and coil voltage to the unit being served in either case; ABB DP is offered in 24 volt and 120 volt coil configurations.
5) Will an ABB DP Series contactor bolt into my existing control panel without redrilling?
The DP Series uses an industry-standard mounting plate with accessible mounting holes, which is what makes it a straight swap into most existing definite purpose contactor footprints in HVAC and refrigeration panels. Measure your current hole spacing before you pull the old unit, and keep the load and control wiring identified as you land it.
6) Is the ABB DP contactor approved for commercial equipment and inspection?
It is UL Listed, and also built to CSA and IEC standards, which covers the usual approval questions on commercial and industrial control panel work in the US and Canada. That matters on food service and refrigeration equipment where an inspector or an OEM spec calls for listed switching components.
7) What is a direct alternative to the ABB DP Series definite purpose contactor?
Square D's definite purpose line covers the same application. The Class 8910 Definite Purpose Contactor and the 8910DP Definite Purpose Contactor in the open (non-enclosed) style are the closest equivalents for panel-mounted HVAC and refrigeration switching. Match on pole count, amp rating, and coil voltage rather than brand, since those three determine whether the replacement actually works on the circuit.
8) What is the difference between the Square D 8910DP open contactor and the ABB DP Series for a panel retrofit?
The Square D 8910DP is supplied in an open construction, meaning it is intended to be mounted inside an existing enclosure or equipment housing. The ABB DP Series uses an industry-standard mounting plate with easily accessible mounting holes so it drops into new or existing control panels, and it is built and tested to UL, CSA, and IEC requirements. Both are definite purpose devices; the decision usually comes down to the mounting footprint already in the panel and the coil voltage your control circuit supplies.
9) I need an 8-pole contactor. Does the ABB DP Series cover that?
The ABB DP Series is offered across a range of amperage ratings, pole configurations, and coil voltages for definite purpose switching. If the requirement is specifically an 8-pole device at 30A, 600V, the Square D 8903L Series Type L multipole lighting contactor is built to that configuration and is electrically held. Confirm the pole count you need against the control schematic before ordering either.
10) Are Square D lighting contactors a drop-in substitute for a failed HVAC contactor?
No. The Square D 8903S Type S and 8903L Type L are electrically held lighting contactors, a different device class from the definite purpose contactors used on HVAC and refrigeration equipment. For replacing a definite purpose contactor, stay with the ABB DP Series or the Square D Class 8910 definite purpose contactor, and match amperage, poles, and coil voltage to the original.
11) Do I need an enclosure with an ABB DP contactor?
Yes, in most installs. A definite purpose contactor like the DP Series is an open device meant to be mounted inside a control panel or equipment cabinet, not hung on a wall by itself. If you need a contactor that already comes configured as an open device for panel mounting, the Square D 8910DP Definite Purpose Contactor, Open is the same arrangement. Plan for a suitably rated enclosure for the location.
12) Is the ABB DP Series suitable for welding equipment, or is that too hard on a contactor?
Welding equipment control is one of the applications the DP Series is built for, alongside refrigeration compressors and HVAC blower motors, where the contactor takes repeated switching cycles. Size it to the equipment's rated current, not to the duty cycle you hope for.
