Information About KCL34125

The KCL34125 is part of Square D’s legacy KCL Series of molded case circuit breakers from Schneider Electric, built on a rugged K-Frame platform. It features a feed-thru connection style with lugs on both ends to accommodate straightforward wiring and panel integration. Designed for compatibility with standard distribution panels and switchboards, it provides dependable protection for three-phase systems operating at higher voltage levels. The breaker incorporates thermal magnetic trip technology with both long-time and instantaneous response to varying fault conditions typical in demanding electrical infrastructure environments.

Key Features:

• 125 A current rating: Handles moderate to heavy load circuits in three-phase systems.
• 480 VAC voltage capability: Suitable for high-voltage industrial and commercial use.
• Thermal magnetic trip: Protects against sustained overloads and immediate fault currents.
• Feed-thru connection: Line and load lugs on both ends for flexible panel wiring.
• 65 kA interrupting capacity: Safely clears higher magnitude faults at 480 V.
• 3-pole configuration: Ensures balanced protection across all phases.
• K-Frame construction: Robust mechanical design common to Square D molded case breakers.
• LI trip functions: Includes long-time and instantaneous trip characteristics.

The KCL34125 delivers the reliability and precision required for dependable overcurrent protection in industrial and commercial electrical systems.
