787-1662/000-250 WAGO AC/DC Power Supplies

Wago 787-1662/000-250 is a 2-channel Electronic Circuit Breaker (ECB) module designed for protection unit applications. It features reactivation of all tripped channels via a 15-58Vdc pulse for a minimum of 500ms. The supply voltage for this module ranges from 32-58Vdc, with a nominal voltage of 48Vdc, and it utilizes push-in CAGE-CLAMP spring connections for secure and straightforward installation. 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 module does not operate with an AC supply voltage. It is designed to function within an ambient air temperature range for operation of -25°C to +70°C and for storage from -25°C to +85°C. The module does not specify a control voltage but includes a T 15A internal fuse per channel, 58Vdc reverse feed protection, and a suppressor diode (68V) for transient suppression on the primary side. The degree of protection is rated at IP20, with a rated insulation voltage (Ui) of 45mm. The dimensions are H90mm x W45mm x D115.5mm, and it is designed to mount on a DIN-35 rail. The response time, resistance, number of available modules, and coating material specifications indicate a focus on durability and compatibility with a wide range of operating environments, specifically noting a 5-96% relative humidity range without condensation.
