G9EK-E Higher-Capacity Screw-Terminal DC Relay
Aratas screw-terminal DC relays are a cost-effective solution for DC disconnect applications
Image of Aratas G9EK-E Higher-Capacity Screw-Terminal DC RelayThe Aratas G9EK-E single-pole, single-throw (SPST) high-power relay is an expansion of the G9EK series, aimed to provide a cost-effective solution for DC disconnect applications. This product is rated to switch 200 A (-E model) or 250 A (-EX model) at 500 VDC bidirectionally, which is up from the standard model’s maximum of 120 A. This eliminates the need for multiple switching components to alternate forward and reverse currents. The G9EK series offers high shock and vibration characteristics coupled with cost-down benefits from hermetically sealed switching predecessors.
Features
Supports high-current DC switching up to 250 A, with model options for 200 A (G9EK-1-E) and 250 A (G9EK-1-EX) operation
Capable of supporting high-capacity DC load switching with automotive-grade shock and vibration support
Bidirectional switching with arc cut-off
Eliminates the need for two relays in the case of DC forward/reverse currents
Swift extinguishing of arc provides a safer switching of high DC voltage loads
Low power consumption
3 W coil power consumption, down from 6 W to 11 W typical in the same relay class
