ABB RXPPK 2H 1MRK001615-AA

Product Introduction

The ABB RXPPK 2H 1MRK001615-AA is a high-performance, industrial-grade relay module designed for demanding protection and control applications within electrical substations and power automation systems. As a core component within ABB’s renowned Relion® protection and control product family, this module serves as a reliable and versatile interface between sensitive protection relays (like REF615, RET615, or similar Relion® devices) and external circuits requiring switching action. Its primary function is to provide electrically isolated, high-capacity contact outputs based on signals received from the controlling relay.

Functionally, the ABB RXPPK 2H acts as an output expansion unit, typically used for tripping circuit breakers, starting fault recorders, signaling alarms, or controlling auxiliary equipment. Its robust design ensures dependable operation even under harsh electrical conditions, such as high inrush currents or inductive loads. The 1MRK001615-AA variant specifically features two high-capacity Form C (changeover) contacts, offering maximum flexibility by providing both normally open (NO) and normally closed (NC) switching options per channel. This positions the ABB RXPPK 2H 1MRK001615-AA as a critical link for executing safety-critical commands within ABB’s comprehensive protection and control architecture, enhancing system reliability and safety.

Core Advantages and Technical Highlights

The ABB RXPPK 2H 1MRK001615-AA delivers significant advantages crucial for mission-critical power systems:

Robust Performance & High Reliability: Engineered for continuous operation in demanding industrial and utility environments, the RXPPK 2H boasts an exceptionally high Mean Time Between Failures (MTBF) figure. Its contacts are rated for high electrical endurance (100,000 operations at full load) and an impressive mechanical life of 10 million operations. This ensures long-term, maintenance-free performance essential for protection circuits where failure is not an option.

Superior Isolation and Safety: Safety is paramount. The module provides reinforced isolation (4 kV AC) between the low-voltage control signal from the relay and the high-voltage/high-current switching circuit. This critical barrier protects sensitive relay electronics from transients and faults occurring in the controlled circuit. Compliance with stringent international safety standards (IEC, UL) is inherent in the design of the ABB RXPPK 2H 1MRK001615-AA, guaranteeing safe integration into global power systems.

Wide Compatibility and Ease of Integration: Designed specifically for seamless integration with ABB Relion® 615 series protection relays and compatible with other Relion® products, the RXPPK 2H features a compact, standardized form factor for easy mounting on DIN rail adjacent to the main relay. Its straightforward screw terminal connections simplify wiring and reduce commissioning time. The wide operating voltage range (18-250V DC / 20-265V AC) enhances its versatility across different auxiliary supply configurations.

Exceptional Environmental Tolerance: Built to withstand extreme conditions, the ABB RXPPK 2H 1MRK001615-AA operates reliably across a wide temperature spectrum (-40°C to +70°C) and offers high resistance to shock, vibration, and humidity. This resilience makes it suitable for installation in challenging locations like outdoor substation control cabinets or industrial plants.

Fail-Safe Design Focus: The use of Form C contacts provides inherent redundancy. If one contact path fails, the alternate state (NO or NC) often remains available for critical signaling or backup control functions, contributing to the overall system’s fault tolerance and availability – a key requirement for protection systems.

Typical Application Scenarios

The ABB RXPPK 2H 1MRK001615-AA finds its primary application in electrical power systems where reliable, isolated switching of high-power circuits based on protection relay commands is essential:

Substation Protection & Control: This is the core application. The module is extensively used to trip high-voltage circuit breakers upon detection of faults (overcurrent, earth faults, differential faults) by Relion® relays like the REF615. The RXPPK 2H‘s high interrupting capacity ensures it can reliably break the trip coil current, even under demanding inductive load conditions. It’s also used for signaling remote alarms (e.g., breaker failure, protection activation) and controlling lockout relays.

Power Generation Plants: Within generation facilities (thermal, hydro, renewable), the ABB RXPPK 2H 1MRK001615-AA provides critical outputs for generator protection schemes, turbine tripping, or initiating emergency shutdown sequences, where absolute reliability and electrical isolation are non-negotiable.

Industrial Power Distribution: Large manufacturing plants, oil & gas facilities, and mining operations rely on robust protection systems. Here, the module interfaces protection relays with motor starters, feeder circuit breakers, or capacitor bank switches, safeguarding expensive equipment from electrical damage due to faults.

Critical Infrastructure Protection: Data centers, hospitals, and transportation networks (railway traction power) utilize the RXPPK 2H as part of their protection systems to ensure power continuity and safety, leveraging its high reliability and safety certifications.

Renewable Energy Integration: In solar farms and wind power substations, the module is used for protection functions like collector feeder tripping or interconnection circuit breaker control, handling the switching duties reliably in often remote and exposed locations.

Installation, Commissioning and Maintenance Instructions

Installation Preparation: Ensure the environment meets specifications (temperature, humidity, cleanliness). Verify DIN rail (35mm) is securely mounted. Have appropriate tools ready: screwdrivers for terminals (follow torque specs in relay manual!), wire strippers, and a multimeter. Crucially, isolate all relevant power sources (auxiliary supply AND the high-voltage/current circuit being switched) before starting work. Carefully review the wiring diagrams for the specific Relion® relay being used. Ensure wiring complies with local codes and standards (wire gauge, fusing). Maintain proper clearance around the ABB RXPPK 2H 1MRK001615-AA module for ventilation.

Maintenance Suggestions: Regularly perform visual inspections for signs of damage, overheating, or loose connections. Keep terminals clean and dust-free. During routine system testing (e.g., using the CMC test set), verify the correct operation of the RXPPK 2H contacts by monitoring the output state while injecting signals to the controlling relay. Check contact resistance periodically if operational issues are suspected. Replacement of the ABB RXPPK 2H 1MRK001615-AA module should only be done with an identical, factory-new unit after ensuring all power is isolated. Strictly adhere to the maintenance schedules and procedures outlined in the relevant ABB Relion® relay technical manuals.
