KA361501021 - 150 Amp Circuit Breaker

KA361501021 - 150 Amp Circuit Breaker

Looking for a high-reliability circuit breaker that easily integrates into commercial or industrial setups? The KA361501021 is a premium molded-case thermal-magnetic breaker built to deliver consistent protection and installation flexibility. Its advanced trip mechanism guards against both long-term overloads and instantaneous shortcuts, while the built-in 120 V AC shunt-trip option permits remote disengagement, making it ideal for higher-level system management. With plug-in compatibility for I-Line panelboards and a service-friendly footprint, this breaker reduces both installation time and future maintenance hassle. Whether retrofitting an aging distribution panel or engineering a new installation, this unit brings dependable performance and peace of mind.

Key Features and Benefits

• Thermal-Magnetic Trip Technology: Combines two methods of fault detection to protect your system from overloads and short circuits, providing full-spectrum safety rather than relying on just one type of protection.
• Integrated 120 V AC Shunt Trip: Enables remote circuit interruption, allowing easier monitoring and control of your distribution network without physically accessing the breaker.
• I-Line Panelboard Compatibility: Designed to drop directly into I-Line plug-in systems for a faster, cleaner installation and minimal downtime when replacing or upgrading.
• Durable Molded Case Construction: Built to handle demanding environments, offering long-term reliability within commercial or industrial applications without over-complex designing.
