GE TEYH3070B - 70 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE TEYH3070B—a 70A, 480V, 3-pole bolt-on molded case circuit breaker built for reliable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. Designed for rugged environments, it uses secure bolt-on mounting to deliver a rigid, vibration-resistant bus connection that stays put where it matters most.

Its thermal-magnetic trip unit provides stable, repeatable protection performance, snapping open on short circuits and gently tracking overloads to protect wiring and devices without nuisance trips. This unit is designed to work in harmony with matching OEM load centers and panelboards, ensuring compatibility and simplified replacements in existing installations.

Key specifications

• Amperage rating: 70 A
• Voltage rating: 480 V
• Poles: 3
• Mounting style: Bolt-on
• Type: Thermal-magnetic molded case circuit breaker
• Application: Branch circuit overcurrent and short-circuit protection

Why this breaker stands out

In contrast to plug-in designs, the bolt-on mounting of the TEYH3070B delivers a sturdier bus connection that resists loosening under vibration—crucial for panel installations in commercial spaces and busy electrical rooms. The thermal-magnetic trip unit couples fast magnetic action for short circuits with reliable thermal protection for overloads, delivering consistent trip characteristics across varying loads and seasonal conditions.

Ideal applications and use cases

• Residential, commercial, and light industrial panelboards and load centers that require reliable 3-pole protection and a bolt-on installation
• New builds and retrofit projects where OEM compatibility with existing GE-style panels simplifies replacement and maintenance
• Locations with moderate vibration or equipment start/stop cycles where a secure, lugged bus connection minimizes movement and wear

Installation and compatibility tips

• Designed to be compatible with matching OEM load centers and panelboards, ensuring a seamless fit in GE-compatible electrical systems
• Use the bolt-on mounting to achieve a rigid connection to the bus—check alignment and secure fasteners to maintain protection performance
• Specifically suitable for branch circuit overcurrent and short-circuit protection, keeping wiring safe in both new construction and maintenance scenarios

Upgrade your electrical distribution with the GE TEYH3070B and enjoy dependable, long-lasting protection for critical circuits in a variety of commercial and residential environments.
