Siemens MXD63B600 Molded Case Circuit Breaker

Siemens MXD63B600 Molded Case Circuit Breaker is a three-pole, 600 A rated molded‑case protection device built on the MXD/MD6 frame for industrial power distribution. It is rated for up to 600 V AC and uses a thermal‑magnetic trip to provide overload and short‑circuit protection, with a 50 kA short‑circuit interruption rating at 480 V. This model includes a shunt accessory (AK) for remote tripping and is designed for bolted‑on panel mounting; lugs are not included. Intended for feeders and distribution circuits in demanding environments, the MXD63B600 offers robust protection in Siemens Sentron MCCB families for medium‑to high‑fault‑current applications.
