NAL36600 - 600 Amp Circuit Breaker

NAL36600 - 600 Amp Circuit Breaker

The NAL36600 is a heavy-duty molded-case circuit breaker rated for 600 A, offering dependable protection for demanding industrial and commercial systems. This thermal-magnetic breaker blends overload protection with instantaneous short-circuit response, giving you confidence that your panels, switchgear, or motor control centers remain safeguarded under harsh conditions. Built in the classic Type NAL style, it supports feed-through installation with mounting legs on both the line and load sides, which simplifies integration into existing switchboards or control gear.

Key Features and Benefits

• Thermal-Magnetic Protection: Combines gradual overload trip and rapid short-circuit interruption in one unit for full-spectrum protection
• High Interruption Capability: Rated up to 100 kA at 240 VAC, 50 kA at 480 VAC, and 25 kA at 600 VAC, making it well-suited for varied voltage systems
• Feed-Through Design: Line-side and load-side mounting legs allow flexible wiring configurations
• Durable Construction: Molded case housing ensures long life and resists damage in harsh environments
• Consistent Performance: Maintains trip characteristics over wide temperature and load ranges
