NCL361200 - 1200 Amp Circuit Breaker

NCL361200 - 1200 Amp Circuit Breaker

The NCL361200 is a 3-pole, 1200-amp molded case circuit breaker made for electrical systems that require the specific fit and ratings of an NCL breaker. It uses a thermal-magnetic trip mechanism and has a cable-in/cable-out configuration, making it a practical fit for compatible existing and legacy equipment. Electrical ratings include 65k AIC at 600VAC, 100k AIC at 480VAC, and 125k AIC at 240VAC. Physically, the breaker measures 19.5 inches high, 11.75 inches wide, and 5.75 inches deep. Those details matter when you’re replacing a breaker in established equipment, where getting the amperage right is only part of the job. Pole count, dimensions, connection style, voltage, and interrupting capacity must all match the application. For systems designed around these specifications, the NCL361200 provides the familiar form, fit, and function needed to keep existing equipment in service. It’s a straightforward, heavy-duty electrical component built to last when used and maintained properly.

Key Features and Benefits
