Siemens Industrial Controls 3UB88334GW2 Relay

Siemens Industrial Controls 3UB88334GW2 Relay

The Siemens 3UB88334GW2 is a professional-grade solid-state overload relay engineered for precise motor protection in demanding industrial HVACR and control environments. Part of the SIRIUS ESP200 series (Catalog No. 48BTG1S00), this Size B electronic relay delivers a broad 25-100 Amp current adjustment range, making it a versatile solution for safeguarding single-phase and multi-phase motor configurations against overcurrent and phase loss. Unlike traditional thermal units, this solid-state design provides consistent accuracy and adjustable tripping class settings (Class 5, 10, 20, or 30), allowing contractors to fine-tune the protection levels based on specific motor startup curves and load requirements.

Designed for seamless integration into Industrial Controls systems, the Siemens 3UB88334GW2 relay features a direct-mount or stand-alone design with window-style main circuit connections and secure screw terminals for the auxiliary circuit. The 1NO + 1NC contact configuration ensures reliable signaling to control boards or alarm systems. With its manual and automatic reset functionality, this 25-100 Amp Overload Relay M/R minimizes system downtime while preventing motor burnout and insulation failure. The robust construction and compact frame make it an essential component for protecting pump controllers, air handlers, and large-scale compressors from hazardous voltage conditions and excessive current flow.

  • Broad Protection Range: The 25-100 Amp current adjustment range allows one unit to cover multiple motor sizes, simplifying truck stock for service technicians.
  • Selectable Tripping Classes: Switchable trip classes (5 to 30) provide tailored protection for different load types, ensuring the relay won't trip prematurely during high-inertia startups.
  • Solid-State Accuracy: Electronic sensing provides superior repeatability and reliability compared to standard bimetallic thermal overloads.
  • Versatile Reset Modes: Features both manual and automatic reset options to accommodate various safety protocols and automated system requirements.
  • Compact Size B Frame: Engineered for space-saving installation within standard control panels and NEMA enclosures without sacrificing performance.
Common Questions & Answers

Is the Siemens 3UB88334GW2 compatible with single-phase motors?
Yes, this solid-state overload relay is specifically designed to support both single-phase and multi-phase applications, providing comprehensive motor protection across various wiring configurations.

What is the advantage of an ESP200 solid-state relay over a thermal overload?
The ESP200 series offers greater accuracy, lower energy consumption, and a wider adjustment range. It eliminates the need for heaters and remains unaffected by ambient temperature fluctuations inside the control cabinet.

How do I set the trip class on this relay?
The trip class (5, 10, 20, or 30) is easily adjusted via the onboard dip switches or dial, allowing you to match the protective response to the specific starting characteristics of your motor.
