Schneider voltage protector can replace EVRPD-480NZ6 (Z5) M

Schneider EVRPD-44U three-phase AC voltage protector can be used as an upgraded replacement product for EVRPD-480NZ5M and EVRPD-480NZ6MThis model is the Schneider EOCR series new generation digital three-phase voltage protector, specifically designed to replace the old EVR-PD/FD series, with upgraded compatibility and functionality.

Core substitution basis

• Frequency compatibilityEVRPD-480NZ5M is compatible with 50Hz power grids, EVRPD-480NZ6M is compatible with 60Hz power grids, and EVRPD-44U supports 40-70Hz broadband and can be compatible with 50/60Hz at the same time, with a wider range of adaptation scenarios.

• Function and specification matchingAll three have core protection functions for overvoltage, undervoltage, phase loss, reverse phase, and three-phase imbalance. The output contacts are all 1C (1-SPDT) specifications, and the installation method supports 35mm rail/panel installation. The control power supply is also consistent.

• Voltage adaptationThe EVRPD-44U has a measurement range covering 100-480V AC/DC, compatible with 480V level power grid requirements, and can directly replace two old models.

Compared to the upgrade highlights of the old model

• Accuracy and functional improvementThe voltage measurement error is only ± 1%, far better than the accuracy of the old model, which is about ± 5V; Added frequency and harmonic measurement, fault recording, and self diagnosis functions for more convenient operation and maintenance.

• More flexible settingsEquipped with digital display and knob adjustment, supporting password locking; The adjustable range of automatic reset time is expanded to 0.5 seconds to 20 minutes, meeting the needs of different scenarios.

Alternative precautions

1. Wiring and DimensionsThe installation holes and wiring terminals are basically compatible with the old model and can be directly replaced for installation.

2. Parameter resetEVRPD-44U is digital and requires resetting protection thresholds and delay parameters for overvoltage, undervoltage, imbalance, etc. according to equipment requirements.

3. Application scenariosSuitable for voltage protection of three-phase equipment such as motors, fans, water pumps, compressors, etc., it can effectively prevent equipment damage caused by power grid fluctuations.

Conclusion

EVRPD-44U can replace EVRPD-480NZ5M and EVRPD-480NZ6M 100%And it has been fully upgraded in compatibility, accuracy, and intelligent functions. When replacing, only the protection parameters need to be reconfigured to be put into normal use, making it an ideal choice for replacing old models.

EOCR, also known as Electronic Over Current Relay, is an intelligent motor comprehensive protector under Schneider Electric (formerly Sanhe, South Korea). It is used to comprehensively protect three-phase/single-phase motors from overload, phase loss, locked rotor, grounding and other faults and damages. The brand was originally owned by SAMWHA in South Korea and was acquired by Schneider Electric in 2001. It is now Schneider's core motor protection product.
