Eaton BQ240220 - 40 A, 240 V, 2-Pole Circuit Breaker | AmpState

The Eaton BQ240220 is a trustworthy 40A, 240V, 2-pole molded-case circuit breaker designed to protect your electrical system from overloads and short circuits. Built for dependable branch circuit protection in panelboards and load centers, this unit combines compact design with reliable performance, making the most of every inch of panel space while delivering consistent protection when it matters most.

Key Features

• Compact molded-case design maximizes panel space and simplifies installation in tight electrical panels.
• Thermal-magnetic trip unit provides stable, repeatable protection against overloads (thermal) and short circuits (magnetic) for predictable interruption behavior.
• OEM-compatible compatibility designed to work with matching Eaton OEM load centers and panelboards for straightforward replacement without adapters.
• 2-pole configuration protects both conductors of 240V circuits, ensuring full, reliable circuit protection.
• Versatile用途 suitable for residential, commercial, and light industrial applications where space efficiency and dependable protection are critical.

Technical Specifications

• Manufacturer: Eaton
• Part Number: BQ240220
• Type: Thermal-magnetic molded-case circuit breaker
• Amperage Rating: 40A

Ideal Use Scenarios

• New installations in panelboards and load centers where a compact 40A, 240V, 2-pole breaker is required.
• Panelboard upgrades to improve protection while maintaining a tight panel footprint.
• Residential subpanels, light commercial, and small industrial applications needing reliable, OEM-compatible protection.
• Replacement scenarios where exact Eaton BQ-series compatibility ensures a smooth, code-compliant swap.

Why This Breaker Stands Out

• OEM-ready compatibility means you can replace similar units without adapters, reducing installation time and potential fitting issues.
• The combination of a molded-case design and a thermal-magnetic trip offers durable protection that stands up to everyday electrical load, while responding quickly to short circuits.
• Designed for a range of environments—from home electrical panels to light commercial panels—without sacrificing space or performance.
• Backed by Eaton’s engineering heritage and the AmpState distribution network, you get consistent performance and availability when you need it.

Compatibility & Installation

• Confirm your panelboard or load center is designed for 240V, 2-pole, 40A protection and can accept Eaton BQ-series breakers.
• Install following the manufacturer’s instructions and local electrical codes; ensure proper conductor sizing and torque as per the panel’s guidelines.
• Maintain labeling accuracy in the panel to reflect the installed protection level for safe operation and code compliance.

Upgrade or equip your electrical system with the Eaton BQ240220 for reliable, space-efficient 40A/240V two-pole protection that aligns with OEM equipment and a wide range of panelboard solutions—ideal for residential circuits, commercial spaces, and light industrial setups.
