1SDAX00057R1

The ABB 1SDAX00057R1 is a DC Power Supply Module specifically designed for the auxiliary control circuits of ABB Emax E1 and E2 series Air Circuit Breakers (ACBs). Its primary function is to convert an external AC supply voltage into a stable, low-voltage DC output to power the critical electronic components of the breaker.

Technical Parameters Parameter Description / Value Manufacturer Part Number 1SDAX00057R1 Product Type DC Power Supply Module for ACB Auxiliary Circuits Compatible Breaker Series ABB Emax E1 & E2 Series Air Circuit Breakers Input Voltage (AC) Commonly 230V AC (Single Phase). Other variants exist (e.g., 120V AC). This MUST be verified as it is the most critical parameter. Input Frequency 50/60 Hz Output Voltage (DC) Typically 24V DC or 48V DC (regulated). Output Power / Current Sufficient to power the trip unit and associated electronics (e.g., 50-100W range). Exact rating must be confirmed. Mounting Plug-in module, mounts directly onto the side of the Emax ACB. Protections Typically includes short-circuit and overload protection on the output side. Primary Function To provide a reliable, isolated DC control voltage for the ACB's electronic systems.
