The C1636M150 is a MicroLogic 6.2 E-M electronic trip unit for the ComPacT NSX100...250 molded-case circuit breaker platform. It is rated 150 A at 65 °C and carries LSIG protection — long-time (L), short-time (S), instantaneous (I), and ground-fault (G) — making it a motor-protection trip unit with adjustable pickup and delay settings. This is a 3-pole unit for fixed-mount circuit breakers, with an LCD display that shows energy metering, protection and alarm settings, time-stamped events, and maintenance indicators. The trip unit technology is electronic, so it offers adjustable long-time pickup from 70 to 150 A and selectable motor tripping classes 5, 10, 20, or 30. The class choice directly affects how long the motor can ride through a stall or protracted start — class 10 is the standard for general-purpose motors; class 20 or 30 for high-inertia loads like fans or centrifuges.
The ComPacT NSX platform is a modular MCCB family for distribution and motor control in industrial panels. The MicroLogic 6.2 E-M is specifically designed for motor protection, with complementary functions like protracted starting time, stalled rotor, current unbalance, and underload detection.
