KA36150 - 150 Amp Circuit Breaker

KA36150 - 150 Amp Circuit Breaker

When you’re responsible for protecting heavy-duty electrical systems in commercial or industrial settings, you need gear that doesn’t just meet standards—it exceeds them. The KA36150 circuit breaker is built to do just that. With a 150 Amp rating and 3-pole design tailored for I-Line panelboard compatibility, this breaker handles weighty current loads while giving you dependable trip performance and high interrupt capacity across multiple voltages. Whether you’re retrofitting an office complex, managing a factory floor power feed, or upgrading a data-center distribution board, the KA36150 delivers the power-system protection you can trust.

Key Features and Benefits

• High Interrupting Capacity: Rated for up to 25 kA at 240 VAC (and 22 kA at 480 VAC or 600 VAC), this breaker handles major fault currents without failing—so you get peace of mind in demanding applications.
• Thermal-Magnetic Trip Technology: Combines fast short-circuit interruption with accurate overload protection—meaning the breaker responds when it must, but isn’t prone to nuisance trips.
• Molded-Case Construction: Tough, sealed molded-case enclosure resists the wear and tear of industrial environments and simplifies installation and maintenance.
• I-Line Panelboard Compatibility: Designed specifically for I-Line systems, making it a clean fit for a typical panelboard architecture—reducing installation headaches.
• Optimized for 60 Hz, 40 °C Environments: Specified for 60 Hz operation and rated for an ambient of 40 °C, this unit is ready for typical commercial/industrial settings without derating surprises.
