SunLee 2 Pole 40 Amp 120V Contactor
The SunLee 2 Pole 40 Amp 120V contactor is designed for HVAC and lighting loads with a 40 FLA amp rating and a 2-pole configuration. Its coil is 120 volts with Class F insulation, providing higher thermal headroom than many 130°C models. It replaces common 2-pole contactors rated at 20–40 amps, making it suitable for condensers, compressors, and heat pumps. This model emphasizes reliable switching in commercial environments and aims to reduce arcing and wear through robust insulation.
Migro 2 Pole 40 Amp Contactor
The Migro 2 Pole 40 Amp Heavy Duty Lighting Contactor offers a 40 A rating with a 120 VAC coil. It comes with a two-year replacement policy, strengthening its value for long-term installations. The device is built for devices up to 600 VAC, with enclosed contacts and encapsulated 120 VAC coil. It is suited for lighting loads and HVAC components that require dependable switching with added protection against arcing.
SunLee 2 Pole 40 Amp 277V Contactor
This 277V coil version is designed for commercial lighting systems and 2-pole configurations, with a 40 A rating and a 277-volt coil. It replaces common 2-pole contactors used in 277V lighting installations, featuring Class F insulation for improved thermal performance. It is appropriate for LED drivers and ballast-controlled lighting setups where higher voltage operation is required.
Baomain 110V 2-Pole 63A Contactor
The Baomain 110V 2-Pole 63A contactor is compact and DIN rail ready, designed for HVAC, motor, pump, and lighting control. It features two normally open contacts (2NO) and a 110V AC rating with a 63A capacity (AC-7a). With a 35mm DIN rail footprint, it fits neatly into control panels and supports safe, multi-circuit control. It requires proper short-circuit protection and spacing for heat management in panel installations.
SunLee 2 Pole 40 Amp 208/240V Contactor
This SunLee model provides a 2-pole, 40 A contactor with a 208/240 VAC coil. It is designed for heavy-duty HVAC replacements and lighting control, offering silver contacts and Class F insulation for improved arc resistance and thermal headroom. The UL recognition supports compliance for US safety standards, making it a solid choice for robust commercial installations requiring 208/240V operation.
Buying Guide
Key considerations when choosing a 2-pole lighting contactor:
- Coil voltage compatibility: Match coil voltage to the control circuit (120V, 208/240V, or 277V) to ensure reliable switching without overloading the coil.
- Current and load rating: Ensure the contactor’s amperage rating (A) covers the connected load, including surge and inrush requirements for motors and lighting ballast.
- Contact material and insulation: Silver contacts and Class F insulation provide better arc resistance and temperature tolerance at higher operating voltages.
- UL/standards compliance: UL recognized or listed products indicate adherence to safety standards in the US, which is important for code compliance.
- Physical size and mounting: DIN rail vs. panel-mount options affect installation in control cabinets; ensure adequate space and mounting method.
- Maintenance and lifecycle: Look for robust construction, protective encapsulation, and warranties or replacement policies for long-term reliability.
- Application suitability: Choose based on whether it’s HVAC condenser/compressor use or lighting control, ensuring compatibility with devices up to the rated voltage and current.
- Thermal headroom: Higher insulation classes (e.g., Class F) offer more temperature tolerance in hot environments, reducing failure risk in demanding spaces.
