NJS-6318 Circuit Breaker

NJS-6318 Circuit Breaker

Trying to match an NJS-6318 circuit breaker already in your equipment? Start with the basics. This breaker uses an NJS frame, has 3 poles, and measures 10.13 inches high, 8.25 inches wide, and 3.88 inches deep. Those details are especially helpful when you’re working with an older electrical system and need to confirm that a replacement has the right physical configuration.

The NJS-6318 is a good fit for maintenance and repair work where keeping the existing system configuration matters. Instead of changing equipment unnecessarily, you can compare the breaker already in place with the NJS-6318 and determine whether the form and fit match your application. It’s built to last and intended for use in compatible electrical equipment.

One thing worth remembering: matching the size isn’t enough. Breakers that appear similar can have different electrical characteristics. Check the part number and frame first, then confirm the required ratings, trip characteristics, mounting, and connections before putting the breaker into service.

Material Compliance and Certifications

• No specific material-compliance or certification information was provided with the available specifications for the NJS-6318. UL, CSA, ANSI, IEC, RoHS, or other certifications should therefore not be assumed.
• If a particular listing or certification is required for the job, check the breaker markings and applicable technical documentation before installation.

Where It Works Best

• The NJS-6318 makes the most sense when you’re maintaining existing electrical equipment that calls for an NJS-frame, 3-pole breaker with the appropriate ratings and configuration. This can include repair and maintenance work on compatible legacy electrical systems where the goal is to keep the original setup in service.
• Already have an NJS-6318 installed? Use the existing breaker as a reference and compare the nameplate information, frame, dimensions, mounting arrangement, terminals, and electrical ratings. The dimensions—10.13 inches high by 8.25 inches wide by 3.88 inches deep—can help with the initial fit check, but the complete specifications still need to match the application.
• For the right equipment, the NJS-6318 gives maintenance teams and electrical professionals a practical option for preserving the required form, fit, and function of the existing system.
