BESCHRIJVING

The 1-1616109-3 is a HARTMAN A-702 Series reverse current cutout relay designed for high-current DC applications. It features SPST NO (Single Pole Single Throw Normally Open) contact arrangement with double-break configuration, rated for 600 amps at 28 Vdc nominal operating voltage. The relay incorporates a reverse current dropout function with a range of 18 to 35 amps and a differential pickup of 0.5 ± 0.15, providing reliable protection against reverse current conditions. It operates continuously with a coil voltage range of 24 to 30 Vdc, pickup voltage maximum of 18 Vdc, and dropout voltage of 0.5 to 7.0 Vdc. The device is gasket sealed with vented construction (Mounting Style A) and offers exceptional reliability with 50,000 electrical operating cycles and 100,000 mechanical cycles at rated load. With a temperature range of -55°C to +71°C and dielectric strength of 1,250 Vrms (all circuits to ground and circuit to circuit), this cutout is ideal for aerospace, marine, and industrial power distribution systems requiring reverse current protection.
