The 1-1971771-4 is a POWER TRIPLE LOCK connector plug housing designed for reliable power and signal connectivity in demanding applications. It features 3 positions with a 6.0 mm centerline pitch and supports wire-to-panel or wire-to-wire configurations. The housing is constructed from thermoplastic material meeting glow wire test requirements (750°C no flame) per IEC 60335-1, with tin-plated copper alloy contacts rated for 19-16 AWG wire gauges (0.65-1.3 mm²). The connector operates at a voltage rating of 600 VAC/VDC with a maximum current rating of 12 amps, and maintains performance across an operating temperature range of -55°C to 105°C. This connector is part of the POWER TRIPLE LOCK system, which provides three enhanced methods of connectivity through cap-to-plug latching, Connector Position Assurance (CPA) devices, and Terminal Position Assurance (TPA) devices, making it ideal for appliance, automotive, and industrial power distribution applications requiring secure, audible connections.
