What the 25 A AC-3 rating means for your motor circuit
The LC1E2501Q5 is a 3-pole (3 NO) contactor from the Easy TeSys Control range, rated 25 A in AC-3 utilisation category at ≤440 V. That AC-3 rating covers starting and stopping of squirrel-cage motors — the 25 A figure governs the full-load current it can switch, not the locked-rotor inrush it must survive. The contactor also carries AC-3e (enhanced electrical endurance for motor duty) and AC-1 (resistive load) ratings, so it handles heater banks or lighting circuits at a higher continuous current if needed. Coil is 380 V AC, a standard European control voltage.
That 45 mm width is a single modular unit (1 TE equivalent), so it slots into a standard enclosure without stealing space from the next device.
Switching timing and mechanical robustness
Vibration resistance: 1.5 Gn open, 3 Gn closed across 5–300 Hz. Shock resistance: 6 Gn open, 10 Gn closed for 11 ms. Rated for operation up to 3000 m altitude without derating.
