What it is — EXTreme Guardian 151034 series
The Molex 1510340014 is the 4-circuit member of the EXTreme Guardian 151034 series — a free-hanging rectangular power receptacle rated 80 A per position at up to 105°C. The housing accepts female blade socket contacts via crimp termination, and the latch-lock fastening keeps the mated pair secured under industrial vibration.
Contacts ordered separately — the one thing that trips up every first order
The spec table flags it explicitly: Contacts Not Included. The 1510340014 is the housing only; you need the matching female blade socket crimp terminals as a separate line item. For a harness repair or BOM fill, that is two order codes — get both before you walk into the cabinet.
Pitch and footprint — 11.00 mm spacing for 4 circuits
At 0.433 in (11.00 mm) pitch in a single-row layout, the 4-position housing fits a compact power-distribution footprint. Free-hanging (in-line) mounting means it is a wire-to-wire or wire-to-panel interconnect — not a board-stack part, so the z-height budget does not apply the way it does on a mezzanine header. The PBT housing material carries a -40°C to 105°C operating window, broad enough for most factory-floor and powertrain environments.
High-current fit — 80 A per circuit
At 80 A per circuit this is a power connector, not a signal connector. The rating applies per contact, so a 4-position fully loaded connector can carry 80 A through each independent blade — your harness gauge and crimp terminal selection must match. The latch-lock fastening is the mechanical keeping-them-mated under load and vibration.
