Technical Parameters Parameter Specification Series / Product Type ABB PY1 Series Accessory / Remote Mounting Connection Base (Socket) Order Code CEPY1-0 Compatible Overload Relay Designed for ABB PY1 series thermal overload relays (e.g., PY1-16 to PY1-125, depending on variant). Rated Operational Current (Ith) Matches the compatible range of the PY1 relay it is designed for (e.g., up to 125A). Rated Insulation Voltage (Ui) 690V AC / 750V DC Rated Impulse Withstand Voltage (Uimp) 6 kV Main Circuit Terminals Screw terminals for connecting main power conductors (from contactor and to motor). Terminal size suitable for cables as per the relay's current rating. Auxiliary Contact Terminals Screw terminals (typically 95-96 for NC trip contact, 97-98 for NO signal contact). Used to connect to the contactor's control circuit. Mounting Snap-on mounting on 35mm DIN Rail. The PY1 relay then plugs or screws onto this base. Material Robust thermoplastic with metal current-carrying parts. Degree of Protection (IP Rating) IP20 (as a component, requires an enclosure for full protection). Ambient Temperature -25°C to +70°C (Operation) Standards Compliance As part of a motor starter assembly, it complies with relevant sections of IEC/EN 60947-1 and IEC/EN 60947-4-1.
