The GX11FA is a 150+ ampere, 12–800 VDC hermetically sealed DC contactor designed for demanding applications requiring high reliability and environmental protection. It features a rugged EPIC seal rated to 175°C, reducing the risk of fire or meltdown in overcurrent conditions, and meets UL1604 for hazardous locations (Class I & II, Div 2 and Class III), IP67 for temporary water immersion, and IP69K for pressure washing. The contactor incorporates built-in coil suppression for all DC coils, eliminating the need for external suppression components, and offers optional high-efficiency dual DC coils with very low continuous power consumption (as low as 1 W for 12 VDC low-power variant). With a mechanical life of 1,000,000 cycles, contact resistance of 0.15–0.3 mO typical, and operating temperature range of -55°C to +85°C, the GX11FA is ideal for battery-powered systems, renewable energy applications, and industrial switching where low EMI emissions and corrosion-free operation are essential.
