787-1664/000-004 WAGO Industrial Automation Components

Wago 787-1664/000-004 is a 4-channel Electronic Circuit Breaker (ECB) module designed for protection unit applications. It features reactivation of all tripped channels via a 15-30Vdc pulse for a minimum of 500ms and allows for the switching ON/OFF of any number of channels via a pulse sequence. The supply voltage requirement is 18-30Vdc with a nominal 24Vdc, 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 of the four channels operates at a rated voltage of 24Vdc. The design includes a status message for each channel conveyed through a pulse sequence and a specialty configuration. It does not operate with an AC supply voltage, and the ambient air temperature for operation ranges from -25°C to +70°C, with storage temperatures ranging from -25°C to +85°C. The degree of protection is IP20, and the rated insulation voltage (Ui) is 45mm. The module is equipped with a T 15A internal fuse per channel, 35Vdc reverse feed protection, and a suppressor diode (33V) for transient suppression on the primary side. The unit's dimensions are H90mm x W45mm x D115.5mm, and it is designed to be mounted on a DIN-35 rail. It can accommodate 5-96% relative humidity (RH) without condensation.
