Why Choose the GA75-10-11 220-230V 50Hz / 230-240V 60Hz [1SBL411025R8011]
The GA75 contactors are specifically engineered for DC circuit switching, addressing the unique challenges of arc suppression inherent to DC applications. Selecting the appropriate contactor requires knowledge of the load 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 effective DC arc interruption. The three contact paths are connected in series using two insulated 25 mm² connectors supplied and fitted as standard. GA75 contactors are single-pole devices; correct polarity must be observed, with terminals clearly marked 1L1 (positive) and 2T1 (negative). An optional side-mounted auxiliary contact block (1 CAL 5-11) is available on GA75-10-11 models. The control circuit operates on AC via a laminated magnetic coil, ensuring reliable performance. A comprehensive range of accessories supports flexible installation and integration.
