Siemens Industrial Controls 3RU2136-4HB0 Relay
The Siemens Sirius 3RU2136-4HB0 is a high-performance thermal overload relay engineered for precise motor protection in industrial environments. Designed for direct mounting on Sirius 3RT203 contactors (Size S2), this bimetallic relay handles a current setting range of 40-50 Amps. It features Class 10 tripping characteristics, ensuring reliable disconnection during overload or phase failure within 10 seconds or less under standard conditions. The 3RU2136-4HB0 utilizes built-in bimetal strips for inverse-time delayed protection and includes temperature compensation to maintain trip accuracy across a wide ambient range of -40°C to +70°C. This S2 frame overload is equipped with integrated 1NO + 1NC auxiliary contacts for fault signaling and offers a selectable manual or automatic reset. For contractors and technicians, this unit provides a robust solution for protecting 3-phase AC motors against unsymmetrical current consumption and single-phasing, minimizing downtime and safeguarding expensive winding assets.
Key Benefits- Direct Integration: Optimized for seamless mechanical and electrical connection to Size S2 3RT20 contactors.
- Phase Failure Protection: Integrated differential slider technology detects phase asymmetry and loss, triggering a rapid trip to prevent motor overheating.
- Flexible Resetting: Easily switch between manual and automatic reset modes via the blue multi-functional button to suit local or remote control logic.
- Compact S2 Footprint: Provides motor protection up to 50A while maintaining a space-saving 55mm width, ideal for high-density control panels.
- Industrial Durability: Rated for an insulation voltage (Ui) of 690V and surge voltage resistance of 6kV, meeting strict IEC and UL safety standards.
Can this relay be used with single-phase loads?
Yes, the 3RU2136-4HB0 can protect single-phase AC or DC loads. To ensure proper tripping, you must connect all three bimetal strips in series so that current flows through each main current path.
Is an adapter required for stand-alone installation?
If you are not mounting this directly to a 3RT2 contactor, a separate terminal bracket for stand-alone installation is required to secure the screw-clamp connections.
Does this unit provide short-circuit protection?
No, thermal overload relays like the Siemens 3RU21 series are designed for overload and phase-loss protection. They must be paired with appropriate fuses or circuit breakers for short-circuit current protection.
