Siemens Industrial Controls 3UB85236EW2 Relay
The Siemens Industrial Controls 3UB85236EW2 Relay is a heavy-duty ESP200 solid-state overload relay engineered for precise protection of 3-phase motors in high-demand HVAC and industrial environments. This unit supports a current adjustment range of 10-40A with a 4:1 FLA dial ratio, allowing for exact field calibration without the need for separate heater elements. Designed to mitigate heat buildup within control cabinets, the 3UB85236EW2 features a self-powered design and ambient-insensitive electronics that ensure consistent trip accuracy of less than 1%. Professionals rely on this Siemens 10/40A overload for its versatile selectable trip classes (5, 10, 20, or 30), which are easily configured via onboard DIP switches to match specific motor start characteristics. With integrated phase loss protection responding in under three seconds and robust ground fault detection, this relay is a critical line of defense for compressors, air handlers, and pump motors. The status is clear at a glance via the visible trip indicator, and the unit supports automatic, manual, or remote reset modes to integrate seamlessly into complex automation frameworks.
Key Benefits
- Reduced Cabinet Heat: Heaterless solid-state design eliminates localized thermal stress and the need for complex ventilation adjustments.
- Broad FLA Adjustability: The 10-40A range with 4:1 adjustment ratio provides flexibility across multiple motor frame sizes.
- Rapid Phase Protection: Safeguards expensive windings with phase loss trips occurring in less than 3 seconds.
- Flexible Integration: Supports DIN rail mounting and features touch-safe threaded terminals for secure, code-compliant installation.
- Selectable Performance: Field-adjustable trip classes ensure compatibility with both standard and high-inertia startup loads.
Common Questions
Does this relay require external power for the electronics?
No, the Siemens ESP200 series is self-powered, drawing required energy directly from the main circuit, which simplifies control wiring.
Can I use the 3UB85236EW2 for single-phase motor protection?
This specific model is designed for 3-phase configurations. While some ESP200 units can be looped for single-phase use, always verify your specific wiring diagram to maintain phase balance protection.
How do I resolve a nuisance trip after a motor fault?
Check the FLA dial setting against the motor nameplate and verify the trip class DIP switches are set correctly for the application's startup duration. Ensure the thermal memory has had sufficient time to reset if the motor was recently overloaded.
