Best Electrically Held Lighting Contactor: Top Picks for Lighting Control Needs
Answering the question “which electrically held lighting cont actor is best for my setup?” this guide highlights concise, surface-to-install options that suit common commercial and residential lighting circuits. Electrically held contactors keep the load energized after the coil is de-energized, making them ideal for applications where the light needs to stay on until a manual or automatic cut-off occurs. The top picks here are best for small to medium lighting loads, with emphasis on ease of installation, reliability, and compatibility with standard 120V or 277/120V systems. Suitable buyers include electricians, facility managers, and DIY enthusiasts working on panel-based lighting control. The following quick table summarizes the four featured products.
| Product | Coil Voltage | Load Rating | Poles | |
|---|---|---|---|---|
| 12 Pole Contactor Normally Open Lighting Contactor 120V Coil | 120V | 60A Resistive/LED, 32A Ballast | 4 x 3 | Multiple-light circuits, DIN rail setups |
| Eaton CN35GN2AB 60A, 2P, Electrically Held | 120V AC | 60A | 2 | Compact two-pole lighting control |
| Eaton CN35BN2AB Nema Electrically Held Open Type | Not specified | 20A | 2 | Open-type, lighter duty lighting |
| 40AMP 4 Pole Designer N/O Contactor (Migro / Electrodepot) | 120V Coil | 40A | 4 | Higher current, compact four-pole design |
12 Pole Contactor Normally Open Lighting Contactor
Brand: Migro
- Coil: 120V, provides electrical hold for lighting loads
- Load rating: 60A resistive/LED, 32A ballast
- DIN rail mount included for quick panel installation
Best for: Projects with multiple lighting circuits in a DIN-rail mounted enclosure where a compact, modular approach helps organize wiring. This unit is well suited for environments needing robust electrical hold with 60A capacity for resistive/LED loads. A potential limitation is the absence of explicit NEMA compatibility details, so users should verify enclosure and wiring standards on arrival.
Eaton CN35GN2AB 60A, 2P, Electrically Held
Brand: Eaton
- Family style: Freedom
- Pole count: 2, Control: 120V AC
Best for: Systems needing a compact two-pole solution with reliable 120V control and standard Eaton compatibility. Choose this if space is limited and you require a familiar brand with straightforward wiring. Limitation: data does not specify coil voltage options beyond 120V and may require verification for non-120V applications.
Eaton CN35BN2AB Nema Electrically Held Contactor
Brand: Eaton
- Family/Style: Freedom
- Amps: 20, Poles: 2
Best for: Light to moderate lighting circuits where NEMA compatibility is a consideration and space is at a premium. Better for smaller loads or spaces where two-pole operation suffices. Limitation: lower current rating at 20A may not cover higher-demand lighting zones.
40AMP 4 Pole Designer N/O Contactor
Brand: Electrodepot
- Load: 40 Amp four-pole, DIN rail mount
- Coil: 120VAC, suitable for lighting with higher current
Best for: Installations requiring a four-pole solution to isolate and switch multiple lighting circuits with a higher current rating. Use this when precise load-switching and robust isolation are priorities. Limitation: datasheet notes 50VA inrush/7VA sealed values; verify actual inrush requirements for your specific lighting loads.
Buying Guide
What should I consider when choosing an electrically held lighting contactor?
Key factors include coil voltage compatibility with your control system, load current rating, number of poles, and DIN rail versus panel mount preferences. If your lights require simultaneous switching of several circuits, a multi-pole model may be ideal. For compact panels, two-pole or four-pole designs that fit standard DIN rails are advantageous. Always confirm whether the contactor supports your specific ballast or LED load.
How to match coil voltage with your control logic
Most lighting contactors use 120V AC coil control in residential and light commercial settings. For 208V or 277V lighting systems, verify coil and contact ratings, or select a model specified for your voltage to avoid improper operation or failure to hold after de-energization.
When is a four-pole model preferable?
Choose a four-pole contactor when you need to switch multiple hot legs independently or want enhanced isolation between circuits. Four-pole units can simplify wiring in multi-circuit lighting runs and provide redundancy for safety-critical paths.
Installation considerations
Ensure DIN rail compatibility if used in enclosed panels, and confirm mounting dimensions match your enclosure space. Look for units with clearly labeled terminals, robust terminals for easy wiring, and compatibility with standard control wiring practices. Check for any additional features such as built-in diagnostics or fuse protection that may simplify maintenance.
Reliability and lifecycle expectations
Electrically held contactors should reliably maintain the load after the control signal is removed. Favor proven brands, verify coil tolerance for ambient temperature, and consider the environment (dust, moisture) where the unit will operate. A properly rated contactor reduces nuisance tripping and improves overall lighting control reliability.
FAQ
- What is an electrically held lighting contactor?
It is a relay-like device that keeps a lighting circuit energized after the control coil is de-energized until actively reset. - Do I need a four-pole contactor for a simple lighting circuit?
Not necessarily; a two-pole model can suffice for single-circuit controls. Four-pole units are better for multi-circuit switching. - Can I mount these on a DIN rail?
Most models in this list include DIN rail mounting compatibility for easy panel installation. - What coil voltage should I choose?
Match coil voltage to your control circuitry, commonly 120V AC in residential settings. Other voltages require compatible models. - Should I worry about inrush rating?
Yes; ensure the inrush rating aligns with your load (for LED, ballast, or heater elements) to avoid tripping or overheating. - What if I have a mixed-load lighting system?
Consider a higher-capacity, multi-pole model that can handle diverse loads and provides safer isolation between circuits.
