ABB RXTUG 22H 1MRK000592-A

Product introduction

The RXTUG 22H 1MRK000592-A is a high-performance current transformer from ABB, designed to accurately measure and monitor electrical currents in medium-voltage industrial systems. As a critical component in power distribution networks, it steps down high primary currents (up to 200 A) to manageable secondary currents (5 A) for safe measurement by meters, relays, and protection devices.

Engineered with dual accuracy classes (0.5 for metering, 10P20 for protection), the RXTUG 22H 1MRK000592-A ensures precise energy measurement for billing purposes while providing reliable data for overcurrent protection systems. Its epoxy resin bushing offers excellent insulation properties, making it suitable for indoor installations in factories, power plants, and commercial buildings. Whether integrated into switchgear or connected to monitoring systems, the RXTUG 22H 1MRK000592-A delivers consistent performance, enabling safe and efficient management of electrical networks.

Core advantages and technical highlights

Dual accuracy performance

The RXTUG 22H 1MRK000592-A combines 0.5-class metering accuracy with 10P20 protection accuracy, eliminating the need for separate transformers. In a manufacturing plant’s main distribution panel, this dual functionality ensures precise energy billing (within ±0.5% error) while enabling fast-acting protective relays to trip during faults—critical for preventing equipment damage.

Robust insulation design

With a 24 kV rated insulation level, the RXTUG 22H 1MRK000592-A safely isolates high-voltage primary circuits from low-voltage secondary equipment. In a 10 kV switchgear installation, this insulation prevents voltage breakdown even during transient surges, protecting sensitive monitoring devices like data loggers and PLC input modules from damage.

Wide operating range

The RXTUG 22H 1MRK000592-A operates reliably from -30°C to +70°C, making it suitable for unheated industrial facilities and cold-climate installations. In a food processing plant with temperature fluctuations, it maintains measurement accuracy regardless of ambient conditions, ensuring consistent performance of both energy monitoring and protection systems.

Typical application scenarios

In a medium-voltage industrial power distribution system, the RXTUG 22H 1MRK000592-A serves as a key measurement and protection component:

• Installed in the main incoming switchgear, it steps down 200 A primary current to 5 A for the energy management system
• Feeds secondary current to protective relays, enabling overcurrent and short-circuit protection of downstream equipment
• Provides measurement data to PLC-based monitoring systems via current transducers
• Supports load balancing across three phases in a 400 V distribution network

In a wastewater treatment plant, the RXTUG 22H 1MRK000592-A monitors current in the main pump motor circuit. Its 10P20 protection class ensures the motor protection relay receives accurate current data during overloads, tripping the circuit breaker before the motor overheats. Simultaneously, its 0.5-class metering accuracy tracks energy consumption for the plant’s sustainability reporting.

Installation, commissioning and maintenance instructions

Installation preparation

Before installing the RXTUG 22H 1MRK000592-A, ensure the power system is de-energized and locked out. The transformer must be mounted on a flat, non-conductive surface using M8 bolts (torqued to 25 Nm). Primary conductors (minimum 16 mm²) connect to the high-voltage terminals, while secondary wiring (1.5 mm²) links to metering/protection devices—ensure secondary circuits are grounded at one point. Verify clearances to other equipment meet local safety standards (minimum 300 mm from live parts).

Maintenance suggestions

Annual inspections of the RXTUG 22H 1MRK000592-A involve checking for epoxy cracks, loose connections, and signs of overheating (discoloration). Use a megohmmeter to test insulation resistance yearly (minimum 100 MΩ at 1 kV). Calibrate every 5 years using a current comparator to maintain accuracy class compliance. If secondary output is erratic, check for shorted turns or loose connections—replace the RXTUG 22H 1MRK000592-A with an ABB-approved spare if internal faults are confirmed, ensuring the replacement matches the original ratio and accuracy class.
