Siemens Industrial Controls 3RB3036-1UB0 Relay
When you are dealing with critical motor protection on the job site, the Siemens 3RB3036-1UB0 is a standard-setting solid-state solution. Designed specifically for the SIRIUS S2 frame size, this electronic overload relay provides a wide current setting range of 12.5 to 50 Amps, allowing for precise field adjustments via the integrated rotary dial. Since this is an S2 solid-state overload relay, it features an internal power supply, eliminating the bulky requirement for external control voltage wiring.
For contractors mounting to SIRIUS 3RT2 contactors, the 3RB3036-1UB0 offers direct-mount capability with robust screw terminal connections for both the main and auxiliary circuits. The Class 10E tripping characteristic ensures rapid response to phase failure and phase unbalance, protecting the motor windings from excessive thermal rise. With built-in manual and automatic reset options, this unit offers the flexibility needed for automated industrial panels or manual equipment restarts. The technical construction follows SIRIUS industrial control standards, ensuring high-accuracy evaluation of motor current through integrated current transformers that trigger the 1NO + 1NC auxiliary contacts during a fault event.
Key Benefits:- Precise Motor Protection: Wide 12.5-50A adjustable range covers multiple motor sizes with a single S2 frame unit.
- Phase Loss Sensitivity: Detects unbalance and phase failure quickly to prevent motor burnout.
- Efficient Installation: Directly mounts to 3RT203 contactors with reliable screw clamp connections.
- Self-Powered Design: The internal power supply reduces panel wiring complexity and potential failure points.
- Flexible Operation: Switchable between manual and automatic reset to match systemic requirements.
- What contactors are compatible with the 3RB3036-1UB0? This relay is engineered for direct mounting on Siemens SIRIUS 3RT203 sequences (Size S2) contactors.
- Does this relay require a separate power source? No, this is a self-powered electronic overload that draws operating energy through the main current transformers.
- What is the difference between Class 10 and Class 10E? The 10E designation indicates an electronic trip profile that provides more accurate and stable tripping characteristics compared to standard thermal bimetallic relays.
