Eaton sqd-qo225 Miniature Circuit Breaker 25A 2 Pole

Product Description

The EATON sqd-qo225 is a 2-pole miniature circuit breaker rated for 120/240 volt AC service at 25 amps with a 10 kA interrupt capacity. It uses a combined thermal and magnetic trip mechanism to protect branch circuits from both sustained overloads and short-circuit faults. The thermal element responds to heat buildup from continuous overloads, while the magnetic element provides near-instantaneous response to high-fault-current events. This breaker is designed for installation in a compatible load center or panelboard and is typically handled by a licensed electrician during panel service or new circuit installation.

This breaker is suited for residential and light commercial applications where a 2-pole, 25-amp branch circuit is required. Common uses include dedicated circuits for HVAC equipment, water heaters, workshop loads, and similar double-pole branch circuit applications. Its compact, plug-in style form factor fits QO-series load centers. It carries a 120/240 VAC rating, making it appropriate for standard North American electrical distribution systems.

Key Features

• 25-amp continuous current rating at 120/240 volts AC
• 2-pole configuration protects both legs of a 240-volt branch circuit
• 10 kA interrupt capacity handles high available fault currents in residential and light commercial panels
• Thermal/magnetic trip provides dual-mode protection against overloads and short circuits
• Plug-in design for compatible QO-series load centers

Compatibility

Designed as a plug-in replacement for QO-series load centers accepting 2-pole miniature circuit breakers at the 25-amp rating. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation must be performed by a qualified, licensed electrician in accordance with NFPA 70 (National Electrical Code) and all applicable local codes. De-energize the panel and verify absence of voltage before handling any breaker or bus connection. Confirm the load center bus bar is rated and listed for this breaker type before installation. Do not exceed the breaker ampere rating with connected load.
