Siemens Industry, Inc. OLRI000CSI Overload Relay

The OLRI000CSI overload relay from Siemens Industry is a thermal motor-protection device designed to trip the circuit when a connected AC motor draws current above its rated range, helping prevent overheating, insulation damage, and premature wear. It provides a precise current setting range of 6.3 to 10.0 A, is Class 10 protection for fast response to overload, and is rated for operation at up to 600 VAC. This unit is intended to be used with compatible Siemens contactors as part of a motor-starting assembly in industrial control panels, providing integrated protection for a wide variety of motors. The OLRI000CSI designation identifies this exact 6.3–10 A, Class 10, 600 VAC overload-relay variant within Siemens’ Allis/OLR family.
