NAL36600 - 600 Amp Circuit Breaker

NAL36600 - 600 Amp Circuit Breaker

The NAL36600 is a 600-amp, 3-pole Type NAL molded-case circuit breaker with a thermal-magnetic trip design. This is the old-style, feed-through NAL configuration, with mounting legs on both the line and load sides. That detail matters when you're replacing a breaker in existing equipment—the mounting arrangement, dimensions, and electrical ratings must match the application. The NAL36600 measures 19.5 inches high, 11.75 inches wide, and 5.75 inches deep. Its interrupting ratings are 25k AIC at 600VAC, 50k AIC at 480VAC, and 100k AIC at 240VAC. For facilities maintaining older electrical equipment, this breaker suits applications that specifically require the Type NAL footprint and feed-through mounting style. It's a straightforward, built-to-last design for keeping compatible legacy equipment in service without changing the original breaker configuration.

Key Features and Benefits

• 600-amp, 3-pole design for compatible three-phase applications.
• Type NAL old-style configuration for equipment designed around this specific breaker style.
• Feed-through mounting with mounting legs on both the line and load sides.
• Thermal-magnetic trip design provides overcurrent and short-circuit protection within the breaker's specified ratings.
• Multiple interrupting ratings: 25k AIC at 600VAC, 50k AIC at 480VAC, and 100k AIC at 240VAC.
• Original-style fit: Useful when maintaining equipment where the existing NAL mounting arrangement and physical dimensions need to be preserved.
• At 19.5" H × 11.75" W × 5.75" D, the breaker has clearly defined dimensions that can be checked against the existing installation.

Material Compliance and Certifications

• The available specifications for the NAL36600 do not include material compliance and certification details, so do not assume any specific listing or certification. If your installation requires a particular agency approval, material standard, or certification, check the markings on the breaker and confirm them against the equipment requirements.

Where It Works Best

• The NAL36600 makes the most sense in existing electrical systems designed for the old-style Type NAL breaker. In particular, it fits applications calling for a 600A, 3-pole thermal-magnetic breaker with the NAL feed-thru mounting arrangement.
  
• When you're working with older equipment, the part number alone isn't the whole story. Check the amperage, number of poles, physical dimensions, mounting arrangement, voltage, and AIC rating against the breaker being replaced. Confirm the mounting legs on both sides, since they define this NAL36600 configuration.
