This 20A, 1-pole circuit breaker is engineered for bolt-on mounting and is specifically suited for 277V systems, making it a practical replacement option for commercial and industrial setups that require solid overcurrent protection with a secure, durable connection.

• Amperage: 20A
• Poles: 1-Pole
• Voltage rating: 277V
• Mounting: Bolt-On
• Part reference: TEYH1020B

What makes this TEYH1020B unique

Unlike generic replacements, this GE circuit breaker is purpose-built to fit panels that accept bolt-on single-pole 277V devices. The 20-amp rating is well-suited for branch circuits powering lighting, outlets, and equipment in commercial environments where 277V distribution is standard. The bolt-on design offers a secure mechanical connection, minimizing drift over time and ensuring consistent electrical contact under load.

Ideal use cases

• Retrofits in office buildings, retail spaces, and warehouses that run 277V lighting and equipment
• Maintenance replacements where panel compatibility is based on a GE part-number reference
• New installations in GE-compatible panels that require a 1-pole, 20A 277V breaker

Why it matters for your project

Choosing the TEYH1020B means aligning with precise GE specifications for reliability and performance. The part-number-centric approach helps you avoid compatibility guesswork during maintenance or retrofit projects. This is especially useful when you’re restoring original panel configurations or upgrading one circuit at a time without overhauling the entire panel.

Installation and safety notes

To maximize safety and performance, confirm the breaker’s fit and ratings against your GE panel before ordering. Use the part number TEYH1020B as the primary compatibility reference, and follow standard electrical practices for bolt-on breakers in 277V circuits. If you’re unsure about panel compatibility, consult your panel’s documentation or a qualified electrician before replacement.

Whether you’re replacing a failed 277V single-pole device or planning a precise retrofit in a GE-legacy panel, the TEYH1020B 20A, 1-Pole, bolt-on circuit breaker delivers dependable protection with a straightforward upgrade path for 277V distribution networks.
