NAL36700 - 700 Amp Circuit Breaker

NAL36700 - 700 Amp Circuit Breaker

The NAL36700 700 A molded-case circuit breaker offers dependable protection for demanding electrical installations. Built for industrial, commercial, and heavy-duty environments, this breaker combines thermal-magnetic operation with a feed-through configuration to give you both sensitive overload protection and quick response to short circuits. The frame’s design—with mounting legs on both the line and load sides—makes installation flexible, whether in motor control centers, power distribution systems, or other high-current configurations.

Key Features and Benefits

• Thermal-Magnetic Protection: Protects against moderate overloads (thermal) and sudden short circuits (magnetic) in one unit — giving you comprehensive circuit safety.
• Feed-Through Style Design: Because mounting legs exist on both the input (line) and output (load) ends, installation is more forgiving and adaptable.
• Tough Molded Case Construction: The molded housing resists mechanical stress and wear, giving longer life under heavy use.
• High Current Rating: At 700 amps, this breaker is built for substantial loads and demanding environments.
• Flexible Fault Handling: With multiple interrupting capacities across different voltage classes, this unit handles a range of fault levels reliably.
