General Electric | TEY315ST12 | Circuit Breaker | 3-Pole | 480V | Bolt-On

General Electric TEY315ST12 circuit breaker delivers reliable, three‑phase protection for 480V systems in demanding industrial environments. Designed for bolt‑on installation, it’s specifically suited for maintenance, retrofit, and replacement projects where exact compatibility matters—ensuring you have the right breaker in the right panel without unnecessary downtime.

• 3-Pole configuration provides synchronized protection across all three phases of a 3‑phase circuit, helping prevent uneven load conditions and equipment damage.
• 480V operating voltage supports common industrial feeders and motor circuits found in manufacturing, processing, and power distribution closets.
• Bolt-On mounting offers streamlined installation in compatible GE panels, reducing installation time and delivering solid, secure contact.
• Part number TEY315ST12 serves as the best reference for compatibility—match this exact model to your panel catalog to avoid mismatches.
• Ideal for maintenance, retrofit, and replacement scenarios where dependable protection and straightforward integration are critical to keep systems running smoothly.

Why this matters in the real world: a 3P 480V bolt‑on breaker like TEY315ST12 delivers consistent trip characteristics across all phases, supporting safer startup sequences and reducing the risk of nuisance trips in multi-motor setups. In retrofit projects, using the precise TEY315ST12 model minimizes panel modifications and preserves existing bus and mounting configurations, saving time and labor.

Practical use cases

• Industrial manufacturing lines with 3‑phase motors and drives needing reliable feeder protection.
• Retrofit projects in GE panels where only bolt‑on, 3P breakers will fit the existing space and wiring layout.
• Maintenance intervals that require a straightforward replacement to restore protective coordination across phases.

Compatibility reminder: Confirm fit and ratings before ordering. The TEY315ST12 part number is the strongest reference to ensure the breaker will match your GE panel and application.
