NJL631225 - 225Amp Circuit Breaker

NJL631225 - 225Amp Circuit Breaker

The NJL631225 is a 225-amp, 3-pole molded-case circuit breaker made for compatible equipment using an NJL-style, bolt-on breaker. It has a thermal-magnetic trip and is rated 22 kAIC at 600VAC, 30 kAIC at 480VAC, and 42 kAIC at 240VAC. If you're replacing a breaker in an existing installation, check those ratings closely, along with the mounting style and physical size. The NJL631225 measures 10.13" high, 8.25" wide, and 3.88" deep and has a 40°C rating. Load-side lug terminals are included. This breaker may also be identified by the part number NJL632225, so seeing that number on equipment records or an existing unit can help when cross-referencing the breaker. For legacy electrical systems, the main consideration is simple: the replacement needs to match what the equipment calls for. When the NJL configuration, 225A rating, three-pole arrangement, dimensions, and interrupting ratings match the application, the NJL631225 provides the form, fit, and function needed to keep compatible equipment in service. It's a straightforward breaker built to last when properly applied and installed.

Where It Works Best

• The NJL631225 circuit breaker is best suited for existing and legacy electrical equipment that requires an NJL 225A, 3-pole, bolt-on molded case breaker with matching electrical ratings and dimensions. This makes it useful for maintenance and replacement situations where the goal is to keep the original equipment configuration.
• A matching part number matters, but you should also check other details. Compare the amperage, poles, voltage, AIC rating, mounting style, dimensions, terminal arrangement, and temperature rating with the breaker being replaced and the equipment's requirements. A qualified electrical professional should confirm compatibility and installation.
