Three pins, friction lock, 7.5 A — what this Economy Power header delivers
The 1877285-3 is a 3-position, single-row, shrouded header from TE's Economy Power series, on a 0.156 inch (3.96 mm) pitch. It terminates through hole with solder and uses a friction lock to secure the mating receptacle — no secondary latch required.
For applications requiring frequent disconnect-reconnect cycles, a gold-plated alternative would extend contact life. The 250 VAC rating suits typical low-voltage power distribution inside an enclosure.
