Schneider Electric KA36125 Circuit Breaker

Schneider Electric's Square D KA36125 Molded Case Circuit Breaker is a three‑pole, 125 A molded‑case protection device designed for 600 V class circuits in commercial and light‑industrial panelboards. The KA family MCCBs employ a thermal‑magnetic trip mechanism, delivering both overload and short‑circuit protection, with an interrupting capacity typically listed as 22 kA at 600 VAC and up to 25 kA at 480 VAC, depending on system voltage. As part of Schneider Electric's legacy KA lineup, KA36125 catalog numbers are completed with phase‑connection suffixes to specify 2P or 3P configurations, allowing flexible integration into a range of distribution schemes. The device's compact frame supports direct mounting within standard panel enclosures and feeders, making it suitable for protecting feeders, motors, transformers, and other three‑phase loads in mid‑size electrical installations. With a 125 A rating and robust interrupting capabilities, the KA36125 provides reliable, standardized protection aligned with Schneider Electric's Square D MCCB lineage, and is commonly deployed where a proven, hard‑working MCCB is required for safety, selectivity, and quick isolation of faults in three‑phase power networks.
