Schneider EOVR/EUVR/PMR voltage protectors

EVR-3P44 is the new generation three-phase voltage protection relay of Schneider Electric's EOCR series, which can directly replace itEOVR-380、EUVR-380、EUVR-440、PMR-440N7Waiting for multiple old models of voltage protectors to achieve seamless integration of functions and application scenarios.

As an upgraded product of the old model, EVR-3P44 integrates comprehensive protection functions such as overvoltage, undervoltage, phase loss, reverse phase, and three-phase imbalance, covering the single or partial protection requirements that the old models focus on. Among them, the overvoltage protection range is 200-550V AC/DC, and the undervoltage protection range is 140-440V AC/DC, suitable for mainstream industrial three-phase voltage systems such as 380V and 440V, and can match the voltage application scenarios of the original model.

In terms of performance and operation, the EVR-3P44 has a measurement accuracy of ± 2%, with an output of 1C conversion contacts. It supports two modes: manual reset (N-type) and 0.5-30s adjustable automatic reset (R-type). The panel is equipped with 5 knobs and 2 dials, which can intuitively adjust parameters such as rated voltage, overvoltage/undervoltage threshold, action delay, imbalance rate, etc. Combined with the power supply, fault indicator light, and TEST self-test button, debugging and troubleshooting are more convenient.

In terms of installation, EVR-3P44 adopts standard 62 (W) × 89.5 (D) × 75 (H) mm size, supports 35mm rail or panel installation, and has a working temperature range of -20 ° C~60 ° C, suitable for various industrial control cabinets and automation systems. Compared to the old model, it has improved in terms of functional integration, adjustment flexibility, and reliability, making it the preferred solution to replace the discontinued or outdated voltage protectors mentioned above.

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.
