NAL36700 - 700 Amp Circuit Breaker

NAL36700 - 700 Amp Circuit Breaker

Looking for an NAL36700 circuit breaker for an existing Type NAL installation? This is a 700-amp, 3-pole, thermal-magnetic molded-case circuit breaker with the old-style NAL configuration. One detail worth checking is the mounting: the NAL36700 has a feed-through design with mounting legs on both the line and load sides. That can make a big difference when you're trying to match a breaker already installed in older equipment. Electrical ratings are 25k AIC at 600VAC, 50k AIC at 480VAC, and 100k AIC at 240VAC. The breaker measures 12.12 inches high, 14.98 inches wide, and 8.07 inches deep. If you're replacing an existing NAL36700, compare the part number, mounting arrangement, dimensions, amperage, poles, and interrupting ratings before installation. These older molded case breakers were built to last, and matching the original specifications can help keep compatible legacy equipment in service without changing the existing breaker configuration.

Key Features and Benefits

• 700-amp rating for applications designed around this specific current rating.
• 3-pole configuration for compatible three-pole electrical systems.
• Old-style Type NAL design for equipment that requires this particular breaker configuration.
• Thermal-magnetic operation consistent with the original NAL36700 design.
• Feed-through mounting arrangement with mounting legs on both the line and load sides.
• 25k AIC at 600VAC, 50k AIC at 480VAC, and 100k AIC at 240VAC.
• Clearly defined dimensions make it easier to compare the breaker with the unit being replaced.
• Designed for use where maintaining the original form, fit, and function is important.

Material Compliance and Certifications

• Specific material compliance information and certification details were not provided with the available NAL36700 specifications. Check the markings on the individual breaker and any supporting documentation when certification or material-compliance requirements apply to the installation.

Where It Works Best

• The NAL36700 makes the most sense in legacy electrical equipment already designed around an old-style Type NAL 700 amp, 3-pole breaker. This is especially important when the existing installation requires the NAL feed-through construction and mounting legs on both the line and load sides.
  
• For replacement applications, don't rely on amperage alone. Check the existing breaker against the NAL36700 part number, physical dimensions, three-pole configuration, mounting style, voltage, and AIC ratings. A close check of those details helps determine whether the breaker matches the equipment it is intended to serve.
