KDL32100 - 100 Amp Circuit Breaker

KDL32100 - 100 Amp Circuit Breaker

Protect your electrical system with confidence using the KDL32100 molded case circuit breaker — a dependable 100 A, 3-pole solution designed for demanding commercial and industrial environments. Built to safeguard circuits from overloads, short circuits, and fault conditions, the KDL32100 delivers high performance and peace of mind for system designers and maintenance teams alike. Its thermal-magnetic trip mechanism responds quickly and precisely under stress, helping to minimize downtime and maintain continuity across critical infrastructure.

Key Features and Benefits

• High Load Capacity: Rated at 100 A, this breaker handles heavy power draws with ease, ideal for feeding motors, panels, or sub-circuits in large systems.
• Fast, Dependable Protection: Utilizes a thermal-magnetic trip design combining both long-time and instantaneous response to detect overloads and fault currents accurately.
• An Interrupting Rating That Holds Up: Supports an interrupting capacity of 25 kA at 240 VAC, giving you margin for high fault currents in robust installations.
• Compact, Serviceable Design: The molded case design and standardized mounting make installation and maintenance straightforward, reducing labor time.
• Common-trip for All Poles: Ensures simultaneous disconnection across all three phases, enhancing system safety and coordination.
