NCL36900 - 900 Amp Circuit Breaker

NCL36900 - 900 Amp Circuit Breaker

Power your high-current systems with confidence using the NCL36900 900A Circuit Breaker — built to deliver dependable protection and simplified installation in commercial and industrial settings. With its solid thermal-magnetic trip mechanism and generous interrupting capabilities, this breaker stands ready to guard equipment, wiring, and personnel from overloads and short circuits. The plug-in I-Line architecture speeds up setup and provides a secure, vibration-resistant connection.

Key Features and Benefits

• High Fault-Interruption Ratings: With interrupting capacities reaching 125 kA at 240 VAC, 100 kA at 480 VAC, and 65 kA at 600 VAC, this breaker handles serious fault currents without compromise.
• I-Line Plug-In Design: Installs in seconds—no bolting, no fuss—while locking into place to resist loosening under vibration or shifting loads.
• Thermal-Magnetic Trip: Offers dual protection — slow thermal response to sustained overloads, and instantaneous magnetic response to major surges.
• Compact Yet Strong: Despite its heavy-duty capability, the molded case construction keeps the footprint manageable while resisting harsh environments.
• Maintenance Friendly: The plug-in style allows quick swap-outs or testing with minimal downtime.
