Why Choose the GAE75-10-00 24V DC [1SBL419025R8100]
GAE75 contactors are engineered specifically for DC circuit switching, addressing the challenges of arc suppression inherent to DC applications. Selection requires accurate knowledge of the load current, voltage, and the circuit’s L/R time constant to ensure reliable operation. These block-type contactors feature main poles equipped with arc chutes incorporating permanent magnets, optimised for effective DC arc interruption. The three contact paths are connected in series via two insulated 25 mm² connections supplied and fitted as standard. Designed as single-pole devices, GAE75 contactors require strict adherence to polarity markings—1L1 for the positive terminal and 2T1 for the negative terminal—to maintain correct operation. The control circuit utilises standard double-winding DC coils with factory-fitted lagging contacts for the insertion of a holding winding, enhancing coil performance. A comprehensive range of accessories is available to support varied installation and application requirements.
