5-1971876-7 is a high-temperature plug housing connector designed for the TE Connectivity POWER TRIPLE LOCK connector system. This component features a 3x5 position configuration with 15 total positions and a 6.0 mm centerline pitch, supporting wire-to-panel or wire-to-wire connections. The housing is constructed from thermoplastic material rated for 150°C operating temperature and meets glow wire test requirements (750°C no flame) per IEC 60335-1, 5th edition, making it suitable for demanding thermal environments. The connector supports a maximum voltage rating of 600 VAC/VDC and current rating up to 12 amps, with operating temperature range from -55°C to +105°C. This plug housing integrates with the POWER TRIPLE LOCK system's three-point locking mechanism (cap latch, CPA, and TPA) to provide secure, reliable connections for power and signal applications in high-temperature industrial and appliance applications.
