KC34150 - 150 Amp Circuit Breaker

KC34150 - 150 Amp Circuit Breaker

Power your system with confidence. The KC34150 is a 150-amp, three-pole thermal-magnetic molded-case circuit breaker engineered for I-Line panelboard systems. Built for heavy use in commercial and industrial settings, it delivers strong protection and consistent performance. It’s designed to safely interrupt fault currents while offering dependable long-term service—even under challenging electrical conditions.

Key Features and Benefits

• High interrupting capacity: Handles up to 65 kA at 480 VAC and 100 kA at 240 VAC, giving you sure protection against severe overcurrent events.
• Thermal-magnetic operation: Combines both overload (thermal) and short-circuit (magnetic) protection in one device, keeping circuits safe under varying loads.
• Molded-case construction: Provides sturdy housing that stands up to industrial rigors with low maintenance needed.
• I-Line compatibility: Engineered to snap directly into I-Line panelboards — simplifies installation and ensures secure mounting.
• Consistent performance at standard duty cycles: Operates reliably at 60 Hz and maintains its trip curve over repeated cycles.
