Eaton GHQRSP2020 - 20 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Eaton GHQRSP2020 20A, 480V, 2-pole bolt-on molded case circuit breaker is engineered to deliver dependable branch circuit protection in panelboards and load centers. Designed for environments where vibration, reliability, and quick protection matter, this unit provides solid performance across residential, commercial, and light industrial applications.

Why the GHQRSP2020 stands out

• Secure bolt-on mounting creates a rigid, vibration-resistant bus connection, reducing movement that can lead to nuisance trips and ensuring consistent contact over time.
• Thermal-magnetic trip unit offers stable, repeatable protection by accurately sensing both prolonged overcurrents and instantaneous short circuits, helping to minimize unnecessary trips while still safeguarding the circuit.
• OEM compatibility is designed to work with matching Eaton loadcenters and panelboards, simplifying replacement, stocking, and field upgrades.
• Versatile electrical rating supports 2-pole, 480V circuits, making it suitable for a range of commercial and light industrial installations where higher voltage protection is required.

What problems this breaker solves

When you need reliable protection for branch circuits without frequent maintenance, the GHQRSP2020 delivers. Its bolt-on design stabilizes connections in panels subject to vibration, the thermal-magnetic trip provides precise protection against overloads and faults, and its compatibility with Eaton OEM panelboards reduces installation complexity and downtime.

• Residential, commercial, and light industrial electrical distributions requiring reliable 2-pole protection at 480V
• Retrofits or replacements in existing Eaton panelboards where a bolt-on solution is preferred for a strong mechanical connection
• New installations where vibration resistance and predictable trip behavior are priorities in busy electrical rooms

Installation considerations and best practices

To maximize performance, ensure the breaker is installed on a compatible Eaton panelboard or loadcenter that accepts bolt-on molded case breakers. Verify ongoing torque on mounting hardware and perform a manufacturer-recommended inspection schedule to maintain the integrity of the bus connection in environments with vibration or movement.

Practical tips from the field

• Pair this breaker with circuits that demand quick, reliable protection without frequent nuisance trips in commercial spaces.
• Use in circuits where higher voltage distribution (480V) is standard to optimize protection coverage and coordination with upstream devices.
• Maintain labeling and documentation for each branch circuit protected by the GHQRSP2020 to streamline future maintenance and inspections.
