The Siemens 3RU2136-4AB0 is a high-quality Siemens SIRIUS Thermal Overload Relay designed for reliable motor overload protection in industrial electrical systems, motor control panels, automation equipment, and motor starter applications. Part of the proven SIRIUS 3RU2 series, this thermal motor protection relay provides an adjustable overload current range of 11–16A with a Class 10 thermal trip characteristic, making it suitable for protecting motors against excessive current and thermal overload conditions. Siemens specifies this relay for inverse-time delayed protection of loads with normal starting conditions against excessive temperature rise caused by overload or phase failure.
The 3RU2136-4AB0 thermal overload relay features an S2 frame size and is designed for contactor mounting with compatible Siemens SIRIUS S2 contactors. It has a 3-pole main circuit, screw terminals for both the main and auxiliary circuits, and manual/automatic reset functionality. With a rated insulation voltage of 690V and surge voltage resistance of 6kV, this Siemens overload relay is designed for dependable operation in demanding industrial motor control environments.
The adjustable 11–16A motor protection range allows the overload setting to be matched to the motor's rated operating current. This Siemens motor overload relay is suitable for DOL motor starters, pump control systems, compressor applications, conveyor systems, HVAC equipment, industrial machinery, packaging machines, OEM control panels, and factory automation systems.
