Information About 3RB2036-1UB0

The 3RB2036-1UB0 is part of Siemens’ SIRIUS motor protection portfolio, engineered to provide precise electronic overload monitoring for AC motors. It supports adjustable current settings and offers selectable manual or automatic reset modes to suit different operational requirements. The relay mounts directly to SIRIUS contactors, reducing wiring complexity and saving panel space. Its solid-state design enhances accuracy and reliability compared to traditional thermal overload relays.

Key Features:

  • Solid-State Motor Protection: Provides accurate electronic overload detection without thermal elements.
  • Adjustable Current Range: Allows precise motor protection tuning across a wide amperage range.
  • Class 10 Tripping: Ensures fast response suitable for most standard motor applications.
  • Phase Loss Detection: Trips rapidly in the event of phase failure or severe imbalance.
  • Direct Contactor Mounting: Designed for seamless integration with Siemens SIRIUS contactors.
  • Selectable Reset Mode: Supports manual or automatic reset configuration.
  • Auxiliary Contacts Included: Features one normally open and one normally closed contact for signaling.
  • Compact SIRIUS Design: Optimized for space-efficient motor starter assemblies.

The 3RB2036-1UB0 delivers the reliability and precision required for protecting industrial motors from electrical faults and abnormal operating conditions.
