Schneider Electric's Square D KAP261501021 is a molded-case circuit breaker (MCCB) rated for 150 A and up to 600 V, designed to protect and switch AC distribution circuits within electrical panels. As part of the Square D lineup, this MCCB provides overcurrent protection for feeders and branch circuits in commercial and light-industrial installations, offering a compact, insulated housing that fits typical panelboard configurations used with Square D MCCBs. The model number identifies a 150 A, 600 V device from Schneider Electric's Square D family, intended for installations requiring reliable protection and rapid isolation of faults in distribution circuits. MCCBs like this one are commonly used in panelboards and switchgear to safeguard electrical infrastructure by interrupting current during overloads or short circuits, enabling safe maintenance and system reliability. For installers, be sure to match the device rating and trip characteristics to the protected circuit, and verify compatibility with the enclosure and busbar arrangement in your Square D panel on site. This part is manufactured by Schneider Electric under the Square D brand, a widely adopted solution in North American electrical distribution, offering consistent performance and availability through authorized distributors and service networks.
