NJJ232350 - 350Amp Circuit Breaker

NJJ232350 - 350Amp Circuit Breaker

When you replace a breaker in older equipment, the small details matter as much as the amp rating. The NJJ232350 is a 2-pole, 350-amp molded-case circuit breaker with a bolt-on mounting style and thermal-magnetic trip. It has an interrupting rating of 22 kA at 240VAC and a 40°C rating. Load-side lug terminals are included.

The breaker measures 10.13 inches high, 8.25 inches wide, and 3.88 inches deep. That's worth noting before installation, particularly when you're working with existing equipment where space, mounting points, and connections are already fixed. If you're trying to match an NJJ232350 already in service, compare more than the catalog number. Also check the amperage, poles, voltage, AIC rating, mounting style, dimensions, and terminal arrangement. For compatible legacy systems that call for these specifications, this breaker provides the form, fit, and function needed for the application. The molded case construction is made to handle its intended job and is built to last when installed and used within its specified conditions.

Material Compliance and Certifications

• Specific certification and material compliance information was not included with the available NJJ232350 specifications. Rather than assume a particular listing or certification applies, check the markings on the breaker and the relevant equipment documentation if your installation has specific compliance requirements.
• As always, install the breaker according to the equipment requirements, applicable electrical codes, and local regulations.

Where It Works Best

• The NJJ232350 circuit breaker is intended for compatible electrical equipment that requires an NJJ-type, 350A, 2-pole bolt-on breaker with the ratings and physical configuration shown above. It can be particularly useful in maintenance and replacement work involving legacy electrical distribution equipment.
• Already have an NJJ232350 that needs to be matched? Start there, but don't stop at the part number. Look at the breaker itself and compare the 350A rating, two poles, 240VAC voltage, 22k AIC rating, thermal-magnetic trip, bolt-on mounting, dimensions, and lug configuration against the equipment requirements.
• With older electrical systems, a close specification match matters. Confirming those details before installation helps make sure the replacement has the correct form, fit, and function for the job.
