ABB RXFILTER P4RX 1KHL001356R0001 EMI Filter & Motor Protection Module

Product Description

Overview

The RXFILTER P4RX 1KHL001356R0001 is an advanced Motor Protection and EMI Filter Module engineered for industrial control systems. It safeguards motors and sensitive electronics against electrical faults, including overloads, phase imbalances, short circuits, and high-frequency interference. By combining real-time diagnostics with robust filtering, the module enhances operational reliability, reduces downtime, and extends equipment lifespan.

This module is widely deployed in ABB Symphony Plus and S900 I/O networks, providing both protection and signal conditioning for industrial control loops.

Key Features

• Motor Protection: Guards against overload, phase failure, short circuit, and thermal stress.

• High-Frequency Noise Suppression: Attenuates differential-mode and common-mode EMI across 150 kHz–30 MHz.

• Transient Voltage Protection: Absorbs surge events from switching operations or external disturbances.

• Real-Time Monitoring: Tracks voltage and current, providing fault diagnostics through LED or LCD display.

• Modular Integration: DIN rail or panel-mountable with minimal insertion loss to primary power or signal paths.

• Optional Communication: Supports Modbus/RS485 for remote monitoring in advanced control systems.

• Industrial Durability: Compact, vibration-resistant design with operation from –20°C to +60°C and storage up to –40°C to +85°C.

Technical Specifications

Applications

The RXFILTER P4RX is suitable for industrial systems requiring both motor protection and electromagnetic interference mitigation, including:

• Power generation and distribution control loops

• Large motor and frequency converter protection

• High-density control cabinets where signal integrity is critical

• Systems requiring compliance with IEC/EN 61000 EMC standards

Installation Notes

Effective grounding is essential. Connect the module to a low-impedance earth bus and terminate field cable shields properly at the filter entry point. This ensures optimal suppression of high-frequency noise and proper surge protection.
