787-1664/000-250 WAGO Industrial Automation Components

Wago 787-1664/000-250 is a protection unit designed as a 4-channel Electronic Circuit Breaker (ECB) module. It features reactivation of all tripped channels via a 15-58Vdc pulse for a minimum of 500ms. The supply voltage is specified at 32-58Vdc with a nominal 48Vdc, and it utilizes push-in CAGE-CLAMP spring connections for connectivity. The rated current is adjustable for each channel via a selector switch, offering settings of 2A, 3A, 4A, 6A, 8A, and 10A. Each channel operates at a rated voltage of 48Vdc. The design includes a signalling contact, and the unit does not specify an AC supply voltage. It operates within an ambient air temperature range of -25°C to +70°C and has a storage temperature range of -25°C to +85°C. The degree of protection is marked as IP20, and the unit includes a 15A internal fuse per channel, 58Vdc reverse feed protection, and a suppressor diode (68V) for transient suppression on the primary side. The UPC code indicates mounting on a DIN-35 rail, and the dimensions are H90mm x W45mm x D115.5mm. It is designed to work within an environment of 5-96% relative humidity without condensation.
