GE TEY140 - 40 A, 277 V, 1-Pole Bolt-On Circuit Breaker | AmpState

GE TEY140 is a 40A, 277V, 1‑pole bolt‑on molded case circuit breaker designed to deliver reliable branch circuit overcurrent and short‑circuit protection in panelboards and load centers. Built for durability and steady performance, this unit is purpose‑built for installations that demand steadfast protection with a secure, vibration‑resistant connection.

What makes the GE TEY140 stand out

• Bolt‑on mounting delivers a rigid bus connection that resists loosening from vibration, helping maintain consistent protection and reducing nuisance trips in commercial environments.
• Thermal‑magnetic trip unit provides stable, repeatable protection for both overload conditions and instantaneous short‑circuit events, safeguarding wiring and connected equipment.
• 277V, 1‑pole, 40A specification is ideal for branch circuits in lighting, control systems, and other 120/277V applications common in modern buildings.
• OEM compatibility works with matching GE OEM load centers and panelboards, ensuring seamless integration and reliable performance within established electrical systems.
• Versatile application suitable for residential, commercial, and light industrial environments where dependable overcurrent protection is essential.

Practical uses and scenarios

Use the GE TEY140 to protect individual branch circuits fed from panelboards or load centers in:

• Residential basements or multi‑unit buildings where a dedicated 40A circuit is needed for heavy appliance or HVAC auxiliary circuits
• Commercial lighting and receptacle runs where 277V distribution is present and reliable interruption protection is crucial
• Light industrial equipment circuits where vibration resistance and secure mounting prevent unwanted tripping

Why this breaker is a smart choice

Choosing the TEY140 means prioritizing long‑term reliability and installation simplicity. The bolt‑on design minimizes connection issues on busy commercial panels, while the thermal‑magnetic protection adapts to both steady loads and fault conditions. With GE’s proven engineering and compatibility with OEM panelboards, you can expect straightforward replacement, consistent trips, and clear protection for critical circuits.

Installation and compatibility considerations

• Ensure mounting is performed on compatible GE OEM panelboards or load centers to preserve intended performance andUL/CSA compliance where applicable.
• Follow standard electrical practices for bolted connections to maintain solid bus contact and minimize voltage drop on the protected circuit.
• Verify that the circuit rating (40A) matches the protected branch circuit design and that the connected conductors and loads are within safe operating limits.

Engineered for dependable, site‑ready protection, the GE TEY140 40A 277V 1‑pole bolt‑on molded case circuit breaker is a precise fit for installers seeking a robust, compatible solution that protects both people and equipment in diverse environments. Trust a component designed to perform when it matters most.
