The PowerFit 750A Line Source connector in black is built for N circuits, combining male contact, silver-plated copper contact construction, and an innovative key-release pin mechanism. For installation, it uses an M40 x 1.5 cable gland with rubber bushing for sealed 300mm² cable assemblies. IP67 protection when mated and a UL94-V0 thermoplastic body help maintain safe performance in demanding touring, event, and industrial environments.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"product-features\"\u003e\n    \u003ch3\u003eKey Features\u003c\/h3\u003e\n    \u003cul\u003e\n      \u003cli\u003e\n\u003cstrong\u003e750A High-Current Rating:\u003c\/strong\u003e 750A Maximum for heavy-duty single-pole power distribution\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eMale Contact Design:\u003c\/strong\u003e Line Source (Male Contact) for mating with compatible PowerFit Line Drain or Panel Drain connectors\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eInnovative Key-Release Pin:\u003c\/strong\u003e Allows fast, convenient, tool-free disconnection during production changeovers\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eCopper Silver-Plated Contact:\u003c\/strong\u003e Excellent conductivity with 0.1m Ohms contact resistance for reduced voltage drop\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eErgonomic Rubber Grip:\u003c\/strong\u003e Enhances handling comfort and control during cable connection work\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eIP67-Rated Cable Sealing:\u003c\/strong\u003e M40 x 1.5 with sealing bushing (Inner Diameter: 22 mm and 33 mm)\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eDurable Thermoplastic Housing:\u003c\/strong\u003e Non-conductive high impact-resistant body with UL94-V0 flame rating\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eVoltage Capacity:\u003c\/strong\u003e 1000V AC, 1500V DC Maximum with 4500V AC test voltage\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eCertified Safety:\u003c\/strong\u003e TUV, CE, RoHS and REACH compliant for professional power distribution systems\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"product-certifications\"\u003e\n    \u003ch3\u003eCertifications \u0026amp;
