The LP1K06105UD3: This is a 3-pole contactor from the TeSys K series, rated 6 A operational current in AC-3 utilisation category up to 440 V. The AC-3 rating covers starting and switching of squirrel-cage motors — the 6 A figure maps to roughly 2.2 kW at 400 V three-phase. AC-4 rating also listed, meaning it can handle inching and plugging duty where the motor is reversed before stopping. The coil is 250 VDC with a built-in bidirectional peak limiting diode suppressor. That suppressor is already inside the contactor body — no external flyback diode needed across the coil terminals. Hold-in power consumption is 3 W at 20 °C. Physical footprint: 1.8 in wide, 2.3 in high, 2.2 in deep (45 x 58 x 57 mm). Pole contact composition is 3 NO (three normally-open main poles). One normally-open auxiliary contact is included on the front.
What to expect on a replacement search
Since this part is obsolete, the natural question is what fits the same footprint and coil voltage. The TeSys K frame shares its mounting and panel cut-out with later TeSys Deca and TeSys F contactors, but coil voltages differ — a 250 VDC coil is uncommon on newer ranges. Pin-compatible direct drop-in is unlikely without verifying the coil circuit. A parametric cross-reference by coil voltage and current rating is the practical path.
