REF542PLUS 2RCA029395 | Integrated Feeder Protection Terminal

ABB REF542PLUS 2RCA029395 Technical Specifications

Main Features and Advantages

The ABB REF542PLUS 2RCA029395 delivers comprehensive feeder protection with integrated control logic in a compact industrial package. This advanced terminal features configurable protection functions including directional overcurrent and voltage-dependent earth fault detection, optimized for industrial distribution networks. Its microprocessor-based design provides high-speed tripping (≤20ms) while preventing nuisance operations through harmonic restraint algorithms. The integrated PLC functionality enables local automation without additional hardware, with logic execution times below 10ms.

Application Areas

The REF542PLUS 2RCA029395 excels in industrial feeder protection and automation. Manufacturing facilities deploy it for critical motor protection circuits in production lines and material handling systems. Energy sector implementations include transformer incomers in utility substations and bus-tie protection in medium-voltage switchgear. Oil and gas applications feature pump control protection in offshore platforms and pipeline compressor stations requiring SIL 2 safety compliance.

Infrastructure applications include airport power distribution networks where selective tripping prevents cascading failures. Mining operations utilize its rugged design for conveyor drive protection in dusty environments. Water treatment plants implement it for critical pump protection with motor start supervision and underload detection. The extended temperature operation (-25°C to +70°C) supports deployment in arctic oil fields and desert solar farms.

Installation and Maintenance

Installation requirements: Mount the ABB REF542PLUS 2RCA029395 vertically on DIN rail using recommended torque values. Maintain minimum 50mm clearance above/below for ventilation. Use shielded twisted-pair cables for communication ports, grounded at one end only. Verify CT polarity and burden capacity before energization.

Maintenance recommendations: Perform annual primary injection tests to verify trip timing accuracy. Check firmware versions against ABB security bulletins quarterly. Clean ventilation slots biannually in dusty environments. Maintain configuration backups offline using PCM600 software. Replace backup batteries every 5 years to preserve event logs during outages.
