Schneider Electric FI36020 Three-Phase Circuit Breaker

FI36020 is a Schneider Electric Square D molded‑case circuit breaker (MCCB) rated for 20 A in a 3‑pole configuration, designed for use on systems up to 600 V AC. As part of the FI family, it employs a thermal‑magnetic trip mechanism to provide overload and short‑circuit protection for three‑phase circuits, and is intended for installation in panel boards or enclosures that accept FI‑series MCCBs. In a three‑phase installation, the device interrupts all three conductors simultaneously to safeguard equipment and wiring. Key specifications include 3P, 20 A, and a 600 V AC maximum rating, with the molded‑case construction suited for robust, enclosure‑based protection in commercial and light industrial distributions.
