Why Choose the GAE75-10-00 110V DC [1SBL419025R8600]
The GAE75 contactors are specifically engineered for DC circuit switching, addressing the greater challenges of arc suppression in DC compared to AC applications. Selection requires knowledge of the breaking current, voltage, and the L/R time constant of the controlled power circuit. These contactors feature a block-type design with main poles equipped with arc chutes incorporating permanent magnets, optimised for reliable DC arc interruption. The three contact paths are connected in series via two insulated 25 mm² connectors supplied and fitted. As single-pole devices, correct polarity must be observed, with terminals clearly marked 1L1 (positive) and 2T1 (negative). The control circuit operates on DC using standard double-winding coils, including a factory-fitted lagging contact for the holding winding. A comprehensive range of accessories is also available to support various installation requirements.
