Square D KC34200 – 200A 480VAC 3‑Pole I‑Line Molded Case Circuit Breaker, KC Frame, Thermal Magnetic, 100kA @240V / 65kA @480V

Description

KC34200

KC34200 is a Square D KC-frame molded case circuit breaker rated for 200 amps and 480 VAC. This 3‑pole breaker uses an I-Line style plug-on connection for quick and secure installation in Square D I-Line panelboards and switchboards.

It features a thermal magnetic trip unit with long-time and instantaneous (LI) protection for reliable defense against overloads and short circuits. The high interrupting capacity at both 240 V and 480 V makes it suitable for a wide range of commercial and industrial power distribution systems. Designed for 3‑phase systems, the KC34200 is rated for continuous operation at 40 °C ambient temperature and meets UL and CSA certifications.

Interrupting Ratings

• 100 kA @ 240 VAC – extra-high interrupting capacity for lower voltages

• 65 kA @ 480 VAC – high interrupting capacity for 480 V systems

• Not rated @ 600 VAC – KC series breakers typically do not have UL listed interrupting ratings at 600 V
