KHL36080 - 80 Amp Circuit Breaker

KHL36080 - 80 Amp Circuit Breaker

Ensure the safety and continuity of your three-phase systems with the KHL36080 80 Amp circuit breaker. Engineered for industrial and commercial power installations, this molded-case, thermal-magnetic breaker delivers surge and short-circuit protection exactly when you need it most. Thanks to its robust interrupting ratings and proven design, it can guard critical loads like motors, generators, HVAC systems, and control panels from overloads or electrical faults.

Key Features & Benefits

• High interrupting performance: Capable of clearing faults with high fault current (e.g. 25 kA @ 600 VAC, 35 kA @ 480 VAC, 65 kA @ 240 VAC), safeguarding equipment and wiring.
• Three-pole design: Built for true three-phase circuits, ensuring balanced load distribution across all phases.
• Fast-acting trip response: The thermal-magnetic mechanism reacts quickly to abnormal current events, reducing downtime.
• Sturdy construction: Made with quality materials that resist harsh industrial conditions and vibration.
• User-friendly installation: Designed to mount into standard enclosures with line/load lug terminals on both ends.
