Square D - Molded Case Circuit Breaker KA36200

The Square D KA36200 is a high-performance molded case circuit breaker (MCCB) designed to provide superior overcurrent protection in demanding commercial and industrial electrical environments. As a member of the renowned K-frame family, this 200-ampere unit ensures the safety and integrity of electrical circuits by preventing damage caused by thermal overloads and high-level short circuits. This circuit breaker is specifically engineered for use with Square D I-Line panelboards and switchboards, utilizing a unique plug-on design that simplifies installation and maintenance.

Reliable Thermal-Magnetic Protection

The KA36200 utilizes a sophisticated thermal-magnetic trip mechanism to deliver dual-layer circuit defense. The thermal component handles persistent overloads by reacting to heat buildup, while the magnetic element provides instantaneous protection against high-magnitude short circuits. This combination ensures maximum uptime for critical machinery while maintaining strict safety standards. The non-interchangeable trip unit provides a factory-calibrated level of precision, ensuring consistent performance throughout the service life of the breaker.

Industrial-Grade Specifications

Built to withstand rigorous operational cycles, the Square D KA36200 features a durable molded casing that provides excellent dielectric strength and mechanical rigidity.

• Current Rating: 200 Amperes for high-capacity power distribution.
• Voltage Rating: Supports operational voltages up to 600VAC.
• Pole Configuration: 3-Pole design for three-phase electrical system compatibility.
