The 078238-2903 is a Powerlock series circular line drain female contact connector designed for high-current applications. It features a Phase 3 shell style in grey with a secondary locking pin fitted to the drain connector, 240 mm crimp contact type, and M40B cable gland accommodating cable outer diameters of 22–32 mm. The connector is rated for a maximum current of 660 A and a maximum rated voltage to earth of 2 kVac or 3 kVdc, with a minimum flashover rating of 9.5 kV (DC or AC peak). It operates reliably across a temperature range of -30°C to +125°C, provides IP67 ingress protection when mated, and achieves IP2X protection against electrical shock. With 500 mating cycles, bayonet mating method, and UL94-V0 flammability compliance, this connector is ideal for demanding industrial and power distribution applications requiring robust, high-current connections.
