The Schneider Electric C10R36M080 is a ComPacT NSX100R three-pole molded-case circuit breaker with a MicroLogic 6.2 E-M electronic trip unit, rated 80 A at 65 °C. It is designed for motor protection — the E-M trip curve provides long-time (L), short-time (So), instantaneous (I), and ground-fault (G) protection, with selectable motor tripping classes 5, 10, 20, and 30.
Mounting and integration details
The LCD display on the MicroLogic trip unit shows energy metering, protection settings, and event logs; the green flashing LED indicates ready state, red LED signals overtemperature at 95 % Ith.
Durability and thermal memory
Mechanical endurance is 20,000 cycles; electrical durability at rated current (80 A, 440 V) is 10,000 cycles, doubling to 20,000 cycles at half-load. The 20-minute thermal memory before and after tripping means the breaker's thermal model retains heat history for that window — useful for re-closing on a motor that has just tripped on overload, avoiding nuisance trips if the motor has not cooled.
