NJJ232150 - 150Amp Circuit Breaker

NJJ232150 - 150Amp Circuit Breaker

Finding a replacement circuit breaker isn't just about matching the amp rating. The mounting, number of poles, interrupting rating, dimensions, and connections must match the equipment you're working on. The NJJ232150 is a 150-amp, 2-pole molded-case circuit breaker for applications using the NJJ configuration. It has thermal-magnetic trip protection, bolt-on mounting, and a 22k A.I.C. rating at 240VAC. It's also rated at 40°C. Size matters, especially when you're working with existing equipment where space and mounting points are already fixed. The NJJ232150 measures 10.13 inches high, 8.25 inches wide, and 3.88 inches deep. Load-side lug terminals are included. If you're maintaining older electrical equipment and need to match an existing NJJ breaker, compare these specifications closely. The NJJ232150 is built to last and is intended for applications where maintaining the existing installation's form, fit, and function matters.

Key Features and Benefits

• 150-amp, 2-pole configuration for equipment designed around these electrical requirements.
• 22 kA.I.C. at 240VAC provides the breaker's specified interrupting rating.
• Thermal-magnetic trip provides overcurrent protection within the breaker's rated application.
• Bolt-on mounting matches equipment designed to accept this NJJ mounting configuration.
• Load-side lug terminals are included, an important detail when matching the connection arrangement of an existing installation.
• Consider the 40°C rating when checking the breaker against application requirements.
• Molded case construction provides the established physical configuration of this breaker type.
• A useful choice for maintenance and replacement work in compatible legacy electrical equipment where the original configuration needs to be maintained.
• Built to last when correctly installed and operated within its intended ratings.

Material Compliance and Certifications

• No specific material compliance or certification information has been provided for the NJJ232150, so adding unverified certifications would be misleading. Check the markings on the breaker and the applicable product documentation when you need to confirm a particular listing, certification, or material requirement.
• As with any circuit breaker replacement, check suitability against the electrical equipment, the application, and applicable electrical codes before installation.

Where It Works Best

• The NJJ232150 circuit breaker is best suited to existing electrical equipment that requires its specific NJJ configuration. It's especially relevant when you're repairing or maintaining a legacy system and need a breaker that matches the required 150 amp rating, two-pole design, bolt-on mounting, and 22k A.I.C. rating at 240VAC.
• A quick word about replacement breakers: don't assume two breakers are interchangeable just because both say 150 amps. Start with the part number and breaker type, then check the pole count, voltage, and interrupting rating, mounting method, dimensions, and terminal setup. For the NJJ232150, those details matter most when you're trying to preserve the existing equipment configuration rather than change it.
• If your equipment is designed for the NJJ232150 and its specifications match the application, this breaker provides the form, fit, and function needed for a straightforward replacement in compatible equipment.
