NA361200 - 1200 Amp Circuit Breaker

NA361200 - 1200 Amp Circuit Breaker

The NA361200 is a 1200A, 3-pole molded case circuit breaker for compatible I-Line plug-in equipment. It uses a thermal-magnetic trip design and is intended for applications requiring this Type NA configuration.

For replacement work, the details matter. The NA361200 measures 12.12 inches high, 14.98 inches wide, and 8.07 inches deep. Its interrupting ratings are 25 kA at 600VAC, 50 kA at 480VAC, and 100 kA at 240VAC.

This breaker is a good fit for maintenance situations where you're trying to keep existing equipment in service without changing its basic configuration. If you're replacing an older breaker, don't go by amperage alone. Check the part number, pole count, mounting style, dimensions, voltage, and A.I.C. rating against the breaker being replaced and the equipment documentation.

It's a straightforward molded case breaker that's built to last in the application it was designed for.

Material Compliance and Certifications

• Specific material compliance information and certification details were not included with the supplied specifications. If your installation requires a particular listing, certification, or material standard, check the markings on the breaker and the applicable equipment documentation before installation.

Where It Works Best

• The NA361200 circuit breaker is best suited to compatible I-Line electrical distribution equipment that calls for a 1200A, 3-pole, Type NA plug-in breaker.
  
• This is especially relevant when maintaining an existing or legacy installation and the goal is to find a breaker that matches what's already there. That means checking more than the 1200A rating. The three-pole configuration, I-Line connection, physical size, voltage, and interrupting rating must all match the application.
