GE TEYL3040B: 40A, 480V, 3-Pole Bolt-On Molded Case Circuit Breaker The GE TEYL3040B is a purpose-built, bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection for panelboards and loadcenters. With a 40-amp rating and 480-volt operation, this three-pole unit is engineered for reliable performance in commercial and light industrial environments, as well as certain residential applications where three-phase protection is required. Why this breaker stands out
- Secure bolt-on mounting for a rigid, vibration-resistant bus connection - When equipment sits in active, vibration-prone spaces, the TEYL3040B maintains a solid, low-resistance connection that reduces the chance of loose contacts and daytime nuisance trips.
- Thermal-magnetic trip unit for stable, repeatable protection - The thermal element handles prolonged overloads, while the magnetic element delivers an instantaneous response to short-circuits, helping to protect conductors and connected equipment without unpredictable trip behavior.
- Three-pole design for three-phase systems at 480V - Ideal for distributing power to 3-phase motors, pumps, conveyors, and other equipment common in commercial and light industrial settings.
- Compatible with matching OEM GE load centers and panelboards - Seamless integration with GE-based electrical infrastructure simplifies replacement, maintenance, and stocking of spare breakers.
- Versatile application across settings - Suitable for residential, commercial, and light industrial projects where reliable three-phase protection at 480V is required. What problems it solves
- Prevents damage from overcurrent and short circuits on 3-phase feeders, helping protect downstream wiring and equipment.
- Reduces downtime and maintenance headaches by delivering predictable, repeatable trip performance, even in environments with vibration or temperature fluctuations.
- Simplifies upgrades or replacements in GE panelboards and load centers with a like-for-like, bolt-on solution that fits established electrical layouts. Who this is for
- Electrical contractors and facility managers upgrading or maintaining panelboards and load centers that require 3-pole, 480V protection.
- Projects involving three-phase motors, pumps, or industrial controls where a robust, bolt-on breaker is preferred.
- Installations aiming for streamlined compatibility with GE OEM equipment and a straightforward replacement path. Use cases and practical scenarios
- Replacing aging protection on a GE-based panelboard feeding a 3-phase motor in a light industrial setting.
- Adding a compliant, three-phase feeder protection point in a commercial building distribution system that operates at 480V.
- Upgrading branch circuit protection in existing GE infrastructure to achieve more stable trip characteristics and reliable operation under varying loads. Delivery-ready performance
- The TEYL3040B is built to deliver consistent, on-demand protection where it matters most: the connection between power sources and critical loads. Its combination of bolt-on rigidity, thermal-magnetic reliability, and OEM compatibility makes it a practical, long-term choice for professionals who value durability and predictable protection. Bottom line
For three-phase, 480V distribution needs, the GE TEYL3040B provides a precise 40A protection solution with a secure bolt-on mount, stable trip behavior, and seamless integration with GE panelboards and loadcenters. It’s a thoughtful, reliable choice when you’re safeguarding branches, motors, and equipment in commercial and light industrial installations.
