Why Choose the GAE75-10-11 125V DC [1SBL419025R8711]
The GAE75 contactors are specifically engineered for DC circuit switching, addressing the unique challenges of arc suppression in direct current applications. Selection requires knowledge of the load current, voltage, and the circuit’s L/R time constant to ensure appropriate breaking capacity. These block-type contactors feature main poles equipped with arc chutes incorporating permanent magnets optimised for DC arc interruption. The three contact paths are connected in series using two insulated 25 mm² connectors supplied and fitted as standard. Designed as single-pole devices, the GAE75 contactors require correct polarity connections, clearly marked as 1L1 (positive) and 2T1 (negative) adjacent to the terminals. Auxiliary functionality is provided via a side-mounted 1 CAL 5-11 add-on auxiliary contact block, available on GAE75-10-11 variants. The control circuit operates on DC with standard double-winding coils, including a factory-fitted lagging contact for the holding winding. A comprehensive range of accessories is available to support varied installation requirements.
