General Electric | TEY3070ST12 | Circuit Breaker | 70A | 3-Pole | 480V

Meet the General Electric TEY3070ST12 Circuit Breaker—a purpose-built solution for serious electrical protection in 3‑phase, 480V systems. With a 70A rating and 3 poles, this GE unit is designed for maintenance, retrofit, and replacement projects where exact specifications matter, ensuring seamless compatibility with existing GE gear and panel boards.

• Amperage: 70 A
• Poles: 3‑Pole
• Voltage: 480V
• Part/Series: TEY family (TEY3070ST12) for reliable, field-proven performance
• Applications: ideal for maintenance, retrofit, and replacement in compatible GE electrical panels and distribution setups

Why this specific GE breaker stands out: it’s built to slot into panels that rely on TEY‑series devices, offering predictable trip characteristics and reliable protection for three‑phase loads at high voltage. When you need to restore protection without reconfiguring an entire distribution system, this 70A, 3‑pole unit provides a precise match to the existing hardware and wiring, reducing downtime and installation risk.

Use cases and ideal scenarios

• Retrofit projects where existing panels require a like-for-like TEY breaker to maintain warranty and performance assurances
• Maintenance events on industrial lines powered by 480V three‑phase distribution
• Replacement of a failed circuit breaker in GE panels designed for TEY devices, avoiding compatibility guesswork
• New equipment startup in facilities with strict OEM spec adherence

Important compatibility note: confirm fit and ratings before ordering. The part number TEY3070ST12 is the best reference to ensure you’re matching the exact GE specification for your panel and system. If you’re cataloging parts or coordinating a service call, use the part number as your primary verification tool to prevent mismatches and unnecessary downtime.

Practical installation considerations

• Power down the equipment and lockout/tagout the circuit before replacement
• Verify that the panel bus rating and conductor sizing align with 480V, 3‑phase operation
• Handle the breaker with appropriate PPE and follow manufacturer torque specifications for lugs and terminal connections

Equip your electrical system with a genuine GE TEY3070ST12 circuit breaker to ensure robust 70A protection, reliable performance, and true compatibility with 3‑pole, 480V installations.
