Schneider Electric FA34100 2 Pole Circuit Breaker

Schneider Electric's Square D FA34100 molded‑case circuit breaker is a three‑pole, FA/I‑Line style MCCB designed for 480V systems, rated at 100A. It uses a thermal‑magnetic trip unit to provide reliable protection for three‑phase feeders in industrial and commercial panelboards and switchboards. With a short‑circuit interrupting capacity of 18 kA at 480V, this FA34100 handles fault currents typical in medium‑voltage distribution without compromising selectivity in properly coordinated installations. The FA34100's FA/I‑Line design supports straightforward installation in compatible enclosures and frame configurations, making it suitable for heavy‑duty protection within 480V distributions.
