Why Choose the GAE75-10-11 110V DC [1SBL419025R8611]
GAE75 contactors are specifically engineered for DC circuit switching, addressing the increased challenges of arc suppression in DC applications compared to AC. Selection requires accurate knowledge of the load current, voltage, and the L/R time constant of the controlled 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 connectors rated for 25 mm² conductors. GAE75 units function as single-pole devices, with clearly marked polarities at terminals—1L1 for positive and 2T1 for negative—that must be observed during installation. Auxiliary contacts are available as side-mounted add-on blocks (1 CAL 5-11) on specific models (GAE75-10-11). The control circuit operates on DC, utilising standard double-winding coils with factory-fitted lagging contacts to enable holding winding insertion. A comprehensive range of accessories supports flexible integration and application.
