TEY Lighting Panel Circuit Breakers
When designing or maintaining a lighting panel, you want circuit protection that is simple, reliable, and specifically designed for lighting loads. You don’t need extra complexity; you only need breakers that are simple to install, work well together, and hold up when a failure happens.
This is where TEY lighting panel circuit breakers come in. These ABB Molded Case breakers are specifically designed for lighting panelboard applications, providing low-cost, high-performance circuit protection for commercial and light-industrial environments.
If you work with ABB lighting panelboards, TEY breakers are one of the most common and reliable options you’ll see.
What Are TEY Lighting Panel Circuit Breakers?
TEY lighting panel circuit breakers are thermal-magnetic, molded-case breakers designed to make branch circuits in lighting panels more safe. They are seen in commercial buildings, schools, hospitals, retail spaces, and industrial sites.
Unlike bigger power breakers, TEY breakers are designed for lighting panelboards and branch circuit loads, giving you a good balance of interrupting capability, space and cost.
Key characteristics include:
- Thermal-magnetic trip units for predictable protection
- Available in 1-, 2-, and 3-pole configurations
- Multiple interrupting ratings to match fault levels
- Compact design for high circuit density in lighting panels
For contractors and facility managers, that means fewer headaches during installation and reliable performance over the life of the panel.
Key Features of ABB Lighting Panelboard Breakers (TEY Series)
When you’re selecting ABB TEY Lighting Breakers, TEY models have features that directly support installations.
- Multiple Short-Circuit Ratings
TEY breakers are available with interrupting ratings for a range of commercial and industrial settings, helping you match breaker capability to available fault current without overspending. - Ambient-Compensated Performance
The thermal-magnetic design helps maintain consistent trip performance even as ambient temperatures change inside a panelboard. - Accessory Flexibility
You can add common breaker accessories like shunt trips, undervoltage releases, and auxiliary switches, great for emergency lighting, controls or monitoring applications. - Compact Footprint
TEY breakers allow high circuit counts in lighting panels, making them a practical choice where space is limited.
These features simplify selecting circuit breaker protection for lighting panels that are reliable.
Circuit Protection for Lighting Panels in Applications
Lighting panels have a specific role — distributing power to branch circuits that feed lighting fixtures, controls, and small auxiliary loads. TEY lighting panel circuit breakers are designed to match that role.
You’ll find ABB TEY Lighting Breakers used in:
- Commercial office buildings
- Healthcare and education facilities
- Warehouses and manufacturing plants
- Retail centers and mixed-use developments
- Data center lighting systems
Because lighting panels are often spread throughout a facility, reliability and ease of service are critical. TEY breakers deliver both, making troubleshooting and replacement easier.
Where TEY Breakers Fit Within ABB Lighting Panelboards
OEM and Engineered Panel Solutions
For OEMs and custom panel builders, TEY breakers give predictable specs with broad availability, which helps reduce design risk and lead time. So, if you’re working with ABB lighting panelboards, TEY breakers are a safe choice.
How to Select the Right TEY Lighting Panel Circuit Breaker
- Amperage Rating – Match the breaker to your lighting branch circuit load
- Number of Poles – Single-pole for typical lighting circuits, multi-pole for shared or three-phase loads
- Voltage Rating – Commonly used on 120/208 V and 277/480 V systems
- Interrupting Rating – Select based on available fault current at the panel
- Accessories Needed – Shunt trip, UV release, or auxiliary contacts if required
Selecting correctly means long-term safety and less tripping.
