KCL34150 - 150 Amp Circuit Breaker

KCL34150 - 150 Amp Circuit Breaker

The KCL34150 is a high-capacity, thermal-magnetic molded-case circuit breaker built to protect demanding industrial and commercial electrical systems. With a 150-amp rating and excellent interrupting values—65 kA at 480 VAC and 100 kA at 240 VAC—this breaker handles high fault currents with confidence. Designed for 60 Hz operation and tested for 40 °C ambient rise, it delivers dependable performance under continuous load. Whether deployed in power distribution panels, motor systems, or heavy machinery lines, this breaker offers the precision and durability you expect from a professional-grade device.

Key Features and Benefits

• High Interrupting Capacity: Rated for 65 kA at 480 VAC and 100 kA at 240 VAC, it provides outstanding fault-current protection in challenging environments.
• Thermal-Magnetic Protection: Combines thermal overload and magnetic short-circuit response to guard systems against both long-term overcurrent and sudden spikes.
• Line & Load Lugs Included: Simplifies installation—no extra parts needed—saving time and reducing labor costs.
• Compact Footprint, Tough Build: The molded-case housing offers mechanical protection, environmental resistance, and long service life even under stress.
• Balanced Load Capability: As a 3-pole breaker, it manages balanced loads across three phases—ideal for three-phase power systems.
