Why Choose the GAE75-10-11 24V DC [1SBL419025R8111]
GAE75 contactors are specifically engineered for DC circuit switching, addressing the unique challenges of arc suppression in direct current applications. Selection requires careful consideration of the breaking current, voltage, and the L/R time constant of the load circuit. These block-type contactors feature main poles equipped with arc chutes incorporating permanent magnets, optimised for reliable DC arc interruption. The three contact paths are connected in series using two insulated 25 mm² connectors supplied and fitted as standard. As single-pole devices, GAE75 contactors require strict adherence to polarity markings—1L1 for the positive terminal and 2T1 for the negative terminal—to ensure correct operation. Auxiliary functionality is provided via a side-mounted 1 CAL 5-11 add-on contact block, available on GAE75-10-11 models. The control circuit employs standard double-winding DC coils, with an optional factory-fitted lagging contact to enable holding winding insertion. A comprehensive range of accessories supports flexible installation and application requirements.
