What this part is and where it fits
The TELEMECANIQUE LP1-D2510ND is a 25 A electrical contactor from the LP1 series, carrying one normally-open and one normally-closed auxiliary contact block integral to the frame. It is a current-production part (lifecycle stage: current). This contactor is designed for switching motor loads in control panels — the 25 A rating covers typical IEC motor starters up to around 5.5 kW at 400 V AC-3 duty, though the exact motor power depends on the specific application voltage and duty cycle. The 1 N/O + 1 N/C auxiliary set handles feedback and interlocking without needing an add-on block for basic circuits.
