Product Description

The Siemens 3RU5136-4EB0 is a versatile thermal overload relay part of the SIRIUS 3RU5 product family, tailored for heavy-duty motor protection. This S2-size device is optimized for mounting on power contactors, offering a broad current setting range from 22 to 32 Amps. It utilizes a bimetallic tripping element to detect overload conditions and phase imbalance accurately. Featuring a Trip Class 10 rating, it provides reliable protection for three-phase motors. With built-in auxiliary signaling contacts and support for both manual and automatic reset, it is an essential component for industrial motor control centers.

Standard Features

  • Phase Failure Sensitivity: Enhanced detection of phase imbalances to prevent motor damage under asymmetric load conditions.

  • Temperature Compensation: Integrated compensation mechanism ensures accurate tripping performance across a wide ambient temperature range.

  • Switch Position Indication: Visible indicator on the front panel provides clear status monitoring of the relay’s trip condition.

  • Stop Function Button: Includes a manual stop button to force the NC contact open for circuit testing or emergency stopping.

  • Screw Terminal Security: Heavy-duty screw terminals provide a gas-tight, vibration-proof connection for high-current applications.

  • Modular System Integration: Fully compatible with the Siemens SIRIUS modular system for streamlined control cabinet engineering.
