NAL361200 - 1200 Amp Circuit Breaker

NAL361200 - 1200 Amp Circuit Breaker

Need an NAL361200 for an existing electrical setup? This is a 1200-amp, 3-pole Type NAL molded-case circuit breaker with the old-style feed-through configuration. It uses a thermal-magnetic trip design and has mounting legs on both the line and load sides, which is important when matching a breaker to equipment already in service. The NAL361200 is rated 25k AIC at 600VAC, 50k AIC at 480VAC, and 100k AIC at 240VAC. Size matters on older installations, too. This breaker measures 19.5 inches high, 11.75 inches wide, and 5.75 inches deep, so check those dimensions along with the electrical ratings and mounting arrangement. For facilities maintaining equipment designed around the Type NAL configuration, this breaker can provide the form, fit, and function required without changing the original breaker setup. It's a straightforward, well-built molded case breaker made for applications where compatibility comes first—and it's built to last.

Key Features and Benefits

• 1200 amp rating for equipment designed around this amperage.
• 3-pole configuration for compatible three-pole applications.
• Type NAL old-style design for matching existing equipment that uses this breaker style.
• Feed-throughconfiguration with mounting legs on both the line and load sides.
• Thermal-magnetic trip design for the intended breaker operation.
• Rated 25k AIC at 600VAC, 50k AIC at 480VAC, and 100k AIC at 240VAC.
• Clearly defined dimensions make it easier to check available mounting space.
• A practical option when form, fit, and functional compatibility with an existing Type NAL installation is the priority.

Material Compliance and Certifications

• The available specifications did not include material compliance details or specific certification or agency-listing information, so do not assume additional certifications. Check the breaker nameplate and applicable equipment documentation to confirm a particular listing, certification, or compliance requirement.

Where It Works Best

• The NAL361200 is best suited for existing electrical distribution equipment built to accept an old-style Type NAL, 1200A, 3-pole feed-through breaker. It's particularly useful in maintenance and replacement situations where keeping the original breaker configuration matters.
  
• Before installation, compare more than just the part number. Check the 1200 amp rating, three-pole configuration, voltage and AIC requirements, physical dimensions, and mounting arrangement against the existing equipment. The mounting legs on both the line and load sides are especially important for this model.
