The 4-1393144-6 is a Potter & Brumfield K10 Series miniature relay featuring a 2 Form C (DPDT) contact arrangement with AgCdO contact material rated for 15A at 120VAC and 10A at 277VAC. The relay supports both AC (6 to 240VAC) and DC (6 to 110VDC) coil options with a Class B insulation system, offering flexible voltage configurations for diverse industrial requirements. It features quick connect terminals (0.187" and 0.160" lengths), operates at frequencies up to 360 operations per hour with a maximum operate/release time of 13/10 ms, and maintains an initial contact resistance of 100mO. The compact miniature form factor (1.375" maximum height) with multiple mounting options (socket, PCB, and flange mount) makes it ideal for space-constrained industrial automation, medical equipment, and motor control systems. The relay is rated for 100,000 electrical operations under standard loads and meets UL 508, IEC 61810, UL E214025, and CSA L15734 approvals, with EU RoHS/ELV and REACH compliance.
