The C1036M025 is a MicroLogic 6.2 E-M electronic trip unit from the ComPacT NSX100...250 range, rated 25 A at 65 °C. It fits 3-pole ComPacT NSX circuit breakers and provides LSIG protection — long-time (L), short-time (S), instantaneous (I), and ground-fault (G) — specifically tuned for motor loads. The 25 A rating at 65 °C means it holds its full ampacity even in a warm panel, so no derating headache for a motor circuit that runs near that ambient.
Built to EN/IEC 60947-2, this trip unit uses electronic sensing with an LCD display for local readout of energy metering, protection settings, and event logs. Motor tripping classes 5, 10, 20, and 30 are selectable, so you match the overload curve to the motor's thermal withstand.
The long-time pickup (Ir) adjusts from 12 to 25 A, and the short-time pickup (Isd) has nine adjustable settings from 5 to 13 x Ir. Ground-fault pickup (Ig) is adjustable as well. Instantaneous pickup (Ii) is fixed. Zone selective interlocking (ZSI) is included, which helps coordinate downstream breakers for faster fault clearing without losing selectivity upstream.
