3-Pole 6.3mm 18A High-Power Terminal Connectors

Engineer robust and safe electrical systems with high-performance Terminal Connectors designed for multi-circuit power transmission. The SH6.3ZC-3PC is a 3-pole (3P) connector with a 6.3mm pitch, engineered to deliver reliable, high-current connectivity in complex electronic and industrial applications. Universally compatible with industry-standard equivalents 9586-3 and AMP:1-1241961-7, this terminal block ensures seamless integration into existing designs and is ideal for use in power distribution, automation controls, and high-wattage appliances requiring stable 3-circuit connections.

Constructed from PA66 UL94V-0 flame-retardant nylon, the housing provides the highest level of fire resistance, self-extinguishing within 10 seconds and preventing flaming drips. This makes the SH6.3ZC-3PC an excellent choice for safety-critical environments such as enclosed control boxes, HVAC units, and consumer electronics where thermal safety is a top priority.

This high-capacity connector is rated for 300V AC/DC and supports up to 18A per contact, significantly exceeding standard 12A terminals. This enhanced power handling capability makes it perfect for demanding applications like motor drives, industrial heating systems, power inverters, and advanced lighting controls where sustained performance and minimal heat buildup are essential.

The internal contacts are precision-made from brass and phosphor bronze, both tin-plated to ensure excellent conductivity, low contact resistance, and long-term durability. Phosphor bronze offers superior elasticity and stress resistance, maintaining firm contact pressure over time—even under repeated thermal cycling and mechanical vibration.

Supporting wire sizes from 24 AWG to 12 AWG, this terminal accommodates a broad range of conductor gauges, including thick wires used in high-power circuits. Its solder-tab design enables secure and permanent PCB mounting, ensuring mechanical stability and reliable electrical performance in demanding environments.

Common applications include industrial machinery, commercial kitchen equipment, power tools, UPS systems, and automotive power modules.
