General Electric TEF113030 30A 1-Pole 277 V Circuit Breaker

Meet the General Electric TEF113030 30A 1-Pole 277 V Circuit Breaker — a focused, dependable solution for protecting single-pole 277-volt circuits. This GE part (Part Number TEF113030) is built to safeguard wiring and connected devices from overloads and short circuits, delivering reliable overcurrent protection where 277V distribution is common.

What it does

Designed for a single hot conductor in 277-volt electrical systems, this circuit breaker trips at 30 amps to prevent overheating, electrical fires, and equipment damage. Its precise 30A rating means it guards circuits that carry higher voltage loads without unnecessary interruptions on lighter draws.

Key specifications

• Part Number: TEF113030
• Current rating: 30 A
• Poles: 1
• Voltage rating: 277 V

Ideal uses and scenarios

• 277V commercial lighting circuits where a robust single-pole protection is required
• Branch circuits feeding small to medium loads in offices, shopping centers, and other commercial spaces
• Retrofits or new installations that demand a 1-pole 277V breaker with a clean, reliable interruption mechanism

Why this GE breaker stands out

This TEF113030 combines GE’s tested design with a straightforward, purpose-driven rating. The single-pole configuration keeps it compact for panel layouts with limited space, while the 277V compatibility makes it a practical choice for high-voltage lighting and equipment circuits. It’s engineered to deliver predictable performance in everyday commercial environments, helping you maintain safe, compliant electrical distribution without overprotection or nuisance trips.

Practical installation and use tips

• Confirm the breaker is appropriate for your panel’s listing and the circuit you’re protecting (277V single-pole applications).
• Ensure the protected load does not exceed 30 amps to maintain proper protection and avoid unnecessary trips.
• Regularly inspect for signs of wear, overheating, or loosening connections in the panel to sustain reliable operation.
