The contactor appears equal to the robust industrial units that I am familiar with from NA over a 50 year career in electrical engineering. The contacts look heavy enough for the current, good insulation, heavy duty connections and the 120 volt coil is powerful and silent. I am running it under load for a month before saying more. Initial thoughts are that this is not your usual Chinese made light weight electrics. Review: Works great, easy installation. ## Features - 3 Pole 40 Amp 240Volt coil - UL 508/UL 60947-4-1 - Silver Cadmium Oxide Contacts - Coils have class F insulation - Base assembly is made from high performance Bulk (Dough) molding compounds ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0888DQ7X8 | | ASIN | B0888DQ7X8 | | Batteries Required? | No | | Country of origin | China | | Customer Reviews | 4.7 4.7 out of 5 stars (344) | | Customer reviews | 4.7 4.7 out of 5 stars (344) | | Date First Available | 5 March 2021 | | Date First Available | 5 March 2021 | | Item Weight | 490 g | | Item model number | DRC-3XU04CG | | Item model number | DRC-3XU04CG | | Manufacturer | sunlee controls | | Manufacturer | sunlee controls | | Material | cadmium | | Product Dimensions | 10 x 6.5 x 8.5 cm; 490 g | | Product Dimensions | 10 x 6.5 x 8.5 cm; 490 g | | Size | 3P 40A 208/240VAC | ## Images ![Sunlee controls 3 Pole 40 Amp contactor 240V coil OEM fits Siemens 42CF35AG equivalent DP Contactor HVAC Contactor - Image 1](https://m.media-amazon.com/images/I/81VuN9J8HYL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How do I know if this is the right contactor for my equipment?** A: If your old contactor has a 240V Coil and is rated 40A, 30A, or 25A. This 40A model is a heavy-duty upgrade for lower amp units. Rule: Coil voltage must be exact; Amps can be higher, but never lower than your original one. **Q: Can I use this on irrigation systems, deep well pumps, Industrial curing ovens, sauna heaters, gymnasium lighting?** A: It's designed for these "Line Voltage Control" applications. Because it features a 208/240V Coil, it matches the high-voltage power source used by this equipment, eliminating the need for a step-down transformer. Make sure coil voltage match. **Q: Does this contactor support Auxiliary Contacts?** A: Yes. This model features standard mounting points on the side for adding auxiliary contact blocks (Snap-on type), check our SUNLEE Auxiliary switch. **Q: I have a 24V thermostat. Will this work for my AC?** A: This contactor has a 240V Coil. Most residential thermostats output a 24V signal. If you connect a 24V thermostat to this 240V coil, it will not engage. Please purchase our model with a "24V Coil" for standard HVAC applications. **Q: My old contactor buzzes/hums — will replacing it fix that?** A: Often yes. Buzzing can be caused by a worn coil/armature, pitted contacts, or low control voltage. Replacing the contactor commonly resolves noise if the control voltage is stable and wiring is correct ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by I***S on 17 September 2024* My initial impression is positive.
