ABB RXPPK 2H 1MRK001615-AA

Product introduction

The RXPPK 2H 1MRK001615-AA is a high-performance surge protection device from ABB, designed to safeguard medium-voltage electrical systems against transient overvoltages caused by lightning strikes, switching operations, and other electrical disturbances. As a critical component in power distribution networks, it limits surge voltages to safe levels, protecting expensive equipment such as transformers, switchgear, and current transformers like the RXTUG 22H 1MRK000592-A.

With a nominal discharge current of 20 kA and a maximum discharge current of 40 kA, RXPPK 2H 1MRK001615-AA provides robust protection for 24 kV systems, ensuring continuity of operation even during severe transient events. Its UV-resistant polyester housing and IP65 rating make it suitable for both indoor and outdoor installations, from industrial substations to renewable energy plants. Whether deployed in new networks or retrofitted into existing infrastructure, RXPPK 2H 1MRK001615-AA delivers reliable surge mitigation, minimizing downtime and equipment damage.

Core advantages and technical highlights

Fast response time

RXPPK 2H 1MRK001615-AA reacts to transient overvoltages in ≤25 ns, ensuring surges are clamped before they reach sensitive equipment. In a wind farm substation, this rapid response protects the RXTUG 22H 1MRK000592-A current transformers and control systems from lightning-induced surges, preventing measurement inaccuracies that could disrupt turbine synchronization.

High surge handling capacity

With Imax of 40 kA, RXPPK 2H 1MRK001615-AA withstands severe surge events, including direct lightning strikes within the protection zone. In a rural distribution network, this capability ensures the device remains operational after a 30 kA strike, continuing to protect the feeder line without requiring immediate replacement.

Durable outdoor design

The IP65-rated polyester housing resists UV radiation, temperature extremes, and moisture, making RXPPK 2H 1MRK001615-AA suitable for pole-mounted or substation installations. In a desert solar farm, it operates reliably in -40°C winter nights and +80°C summer days, maintaining protection for inverter stations without performance degradation.

Typical application scenarios

In a 24 kV urban distribution network, RXPPK 2H 1MRK001615-AA is installed at the incoming feeder of a commercial district substation:

• Protects transformers and switchgear from lightning surges traveling along overhead lines.
• Works alongside RXTUG 22H 1MRK000592-Acurrent transformers, ensuring accurate metering even after surge events.
• Limits overvoltages to ≤65 kV, preventing insulation breakdown in cables and switchgear.

This application reduces outage duration by 70% during thunderstorms, maintaining power supply to hospitals, data centers, and residential areas. The device’s flange mounting allows easy installation on substation busbars, with clear labeling facilitating quick visual inspections.

In a renewable energy park with multiple 24 kV collector lines, RXPPK 2H 1MRK001615-AA protects each line’s junction box:

• Clamps surges generated by nearby lightning strikes, safeguarding string inverters and combiner boxes.
• Coordinates with downstream surge protectors to create a layered protection system, reducing energy let-through to sensitive electronics.
• Its rugged design withstands vibration from wind turbines, ensuring long-term reliability in dynamic environments.

Installation, commissioning and maintenance instructions

Installation preparation

Before installing RXPPK 2H 1MRK001615-AA, de-energize the 24 kV system and verify isolation with a voltage tester. Use M12 stainless steel bolts (torque to 35 Nm) to mount the device on a flat, grounded surface, ensuring a minimum 300 mm clearance to live parts. Connect the line terminal to the phase conductor (120 mm² minimum) and the ground terminal to the substation grounding grid (95 mm² minimum), using copper lugs with proper crimping. Check that the device’s orientation matches the phase-to-ground protection requirement, with the ground terminal pointing downward to prevent water accumulation.

Maintenance suggestions

Inspect RXPPK 2H 1MRK001615-AA quarterly for physical damage, including cracks in the housing or loose connections. Use an insulation resistance tester annually to verify megohmmeter readings >10 GΩ at 2.5 kV. Record surge counter values (if equipped) to track event frequency—values exceeding 10 surges/year may indicate inadequate upstream protection. Replace RXPPK 2H 1MRK001615-AA if the housing is cracked, or if leakage current exceeds 1 mA at 1.1×Uc. When replacing, use only ABB-approved spares to maintain protection class compliance.
