Description

Product Overview

The UFC921A101 (Part No. 3BHE024855R0101) is a precision current measuring board manufactured by ABB for industrial drive and power conversion systems. Engineered to handle a rated current of 100 A across an input voltage range of 0-400 V AC (50/60 Hz), this compact module measures 12 cm x 10 cm x 5 cm and weighs 1.76 lbs (0.8 kg). Housed in an IP20 enclosure, it mounts easily on standard DIN rails for reliable electrical monitoring in demanding industrial environments.

Core Technical Advantages

  • High-Precision Current Sensing: Accurately measures up to 100 A AC with a tight measurement accuracy of ±1.5%.
  • Wide AC Voltage Range: Supports 0-400 V AC input across standard 50/60 Hz industrial power frequencies.
  • Robust Thermal Tolerance: Operates reliably across an ambient temperature range from -10 °C to +55 °C.
  • Space-Saving DIN Rail Design: Compact 12x10x5 cm footprint allows quick and secure snap-on mounting inside control cabinets.

Wiring & Installation

System Power De-energization

Always isolate and lock out main power to the control panel before installing or servicing the UFC921A101 current measuring board.

DIN Rail Mounting

Securely snap the 0.8 kg module onto a standard industrial DIN rail inside an IP20 or better protective enclosure, ensuring proper vertical orientation for airflow.

Current & Voltage Wiring

Connect input voltage lines (up to 400 V AC) and current monitoring leads to the designated terminal blocks, using properly sized copper conductors to handle up to 100 A.

Functional Verification

Inspect all wiring connections for secure clamping, restore system power, and verify measuring output signals against control system diagnostic software.

Engineering Advantages

  • High Current Handling: Engineered to monitor up to 100 A AC reliably with minimal thermal drift.
  • Accurate Signal Feedback: Maintains a strict ±1.5% accuracy threshold across standard 50/60 Hz power networks.
  • Compact Form Factor: Small 12x10x5 cm footprint optimizes internal cabinet space allocation.
