General Electric THEF113020 20A 1-Pole 277 V Circuit Breaker

General Electric THEF113020 is a purpose-built 20A, 1-pole circuit breaker designed for 277-volt electrical systems. If you’re upgrading a panel or replacing a failed unit, this GE breaker delivers targeted overload protection for a single leg of your 277V circuit, helping keep sensitive lighting and equipment safe.

• Current rating: 20 A
• Poles: 1
• Voltage rating: 277 V
• Part number: THEF113020
• Brand: General Electric

Ideal use cases

• Protects a single branch circuit in commercial environments where 277V lighting and equipment are common, preventing overheating and potential damage due to overloads.
• Designed for replacement in GE panels or systems that accommodate this 20A, 1-pole 277V configuration, making maintenance straightforward and reliable.
• Useful when upgrading older circuits to a modern, dedicated 20-amp protection device tailored for 277V operation.

Why this matters

• Automatic interruption of current on overload reduces the risk of heat buildup and electrical fires, contributing to safer building operation and less downtime.
• With a clear 20A rating, it aligns well with typical lighting and general-purpose branch circuits found in commercial spaces that run at 277V, helping you match protection to actual load demands.

Practical guidance

• Before installing, confirm your panel accepts the THEF113020 model and that the circuit load is at or below 20A. If in doubt, consult a licensed electrician to ensure proper fit and safe operation.
• Keep this part handy for routine maintenance or quick replacement to minimize disruption in facilities relying on 277V systems.
