Schneider Electric MHCA216 Molded Case Circuit Breaker

The Schneider Electric MHCA216 is a two-pole, 100-amp molded‑case circuit breaker from Square D, part of the legacy MH family designed to protect low‑voltage distribution circuits by interrupting overloads and short circuits. As a molded‑case breaker, it fits in MH‑series panels and enclosures that require Square D/MH devices. This 2‑pole unit is intended for use on 240 V nominal circuits in commercial or light‑industrial electrical systems. The MH family is a long‑standing line of molded‑case breakers that historically includes devices with thermal‑magnetic trip provisions (and magnetic‑only variants), reflecting Square D’s legacy approach to overcurrent protection. Because MHCA216 is a legacy model, verify panel compatibility and labeling before attempting replacement in any equipment.
