Eaton BQ240230 - 30 A, 240 V, 2-Pole Circuit Breaker | AmpState

The Eaton BQ240230 30A, 240V, 2-pole molded case circuit breaker is designed to deliver dependable branch circuit protection for panelboards and loadcenters. With a compact molded case and a thermal-magnetic trip unit, this breaker offers precise, repeatable protection that stays consistent across varying temperatures and loads.

What makes this breaker unique

• Compact molded case design maximizes panel space, making it easier to fit multiple circuits in tight panel enclosures without compromising protection.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining thermal sensing for overcurrent with magnetic trip for immediate short-circuit response.
• 2-pole configuration ensures both hot legs disconnect simultaneously, preventing dangerous unbalanced conditions on 240V circuits.
• OEM-compatible design ensures reliable operation with matching loadcenters and panelboards, simplifying replacements and upgrades.
• Versatile applications built for residential, commercial, and light industrial environments where dependable 240V protection is essential.

Ideal use cases

• Protecting 240V branch circuits in homes—think HVAC equipment, water heaters, electric dryers, and large appliances.
• Commissioning or upgrading panelboards in small offices, retail spaces, or workshops where space is at a premium.
• Light industrial setups with motors and equipment requiring robust overcurrent and short-circuit protection.

Technical snapshot

• Manufacturer: Eaton
• Part number: BQ240230
• Type: Thermal-magnetic molded case circuit breaker
• Amperage rating: 30A
• Voltage rating: 240V
• Number of poles: 2
• Application: Branch circuit overcurrent and short-circuit protection

Why it matters and practical benefits

• By disconnecting both hot legs on a 240V circuit, it minimizes the risk of parallel faults and protects equipment more effectively than single-pole alternatives.
• The compact form factor helps you maximize panel capacity, which is especially valuable when wiring multiple 240V loads in residential or commercial panels.
• OEM compatibility means you can source this breaker with confidence for replacements or panel upgrades, reducing downtime and ensuring consistent trip characteristics.
• Reliability across temperature variations makes it suitable for garages, basements, outdoor-rated panels, and other environments where ambient conditions can shift.

Tips for best results

• Confirm the panelboard or loadcenter model is compatible with the BQ240230 to ensure seamless mounting and electrical connection.
• When replacing an existing breaker, match the amperage rating (30A) and ensure the replacement is the same type (two-pole molded case) to preserve protective characteristics.
• Follow panel manufacturer torque specifications for terminal connections to maintain reliable lugs and prevent loosening over time.
• Use this breaker for circuits where a balanced 240V load is common, such as motors, compressors, and large appliances, to maintain stable performance.
