Three phase voltage protector

EVR-3P44 belongs to Schneider Electric's EOCR series three-phase AC voltage protection relay, mainly used for abnormal power supply protection of three-phase electrical equipment such as motors, fans, water pumps, compressors, etc. in industrial settings. It can effectively avoid equipment damage or operational failures caused by voltage problems.Three phase voltage protector

This protector has comprehensive voltage monitoring and protection functions, supporting overvoltage, undervoltage, three-phase imbalance, phase loss, and reverse phase protection. The overvoltage protection range is adjustable from 200-550 V AC/DC, and the undervoltage protection range is adjustable from 140-440 V AC/DC. At the same time, the three-phase imbalance ratio can be set to quickly respond to power supply abnormalities.

In terms of electrical parameters, the rated operating voltage of EVR-3P44 is 200-440 V AC (50/60 Hz), with a measurement accuracy of ± 2%. The output is a 1C conversion contact, suitable for conventional control circuit signal output. The device supports two modes: manual reset and automatic reset. The automatic reset time can be adjusted within the range of 0.5-30s to meet the control needs of different sites.

The EVR-3P44 panel is equipped with multiple knobs and dials, which can intuitively adjust parameters such as rated voltage, overvoltage value, undervoltage value, action delay, and imbalance rate. It is also equipped with a power supply and fault indicator light, combined with the TEST self-test reset button, for easy on-site debugging and fault troubleshooting.

This product adopts standard size design, supports 35mm rail installation or panel installation, and has a working temperature range of -20 ° C~60 ° C. It is suitable for various industrial environments, distribution cabinets, and automation systems with high power supply quality requirements. It is a commonly used protective element for stable operation of three-phase equipment.Three phase voltage protector

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.
