LSA-H3P50YB Phase Relay FCNGEVBH 50A 220V/380V State Regulator

Description

Product Overview

The LSA-H3P50YB Phase Monitoring Relay is engineered to provide precise voltage regulation in single‑phase industrial environments. Manufactured by FCNGEVBH, this solid‑state device combines a compact form factor with robust performance, handling up to 50 A at input voltages ranging from 220 V to 380 V. Its sealed construction protects internal components from dust, moisture, and other contaminants, ensuring long‑term reliability. The relay monitors phase conditions continuously and activates protection mechanisms the moment an abnormal voltage event is detected, preventing damage to downstream equipment. Key specifications include a compact package measuring 1.18 × 0.79 × 0.39 inches, a lightweight design of 1.76 oz, and compliance with industry standards for phase monitoring relays. The device is suitable for a wide range of applications, from motor control centers to automation panels, delivering consistent performance in demanding settings.

Usage

This relay is designed for general‑purpose industrial use where reliable phase monitoring and voltage regulation are critical. It excels in environments such as manufacturing plants, processing facilities, and utility substations, where low‑power loads like sensors, control circuits, and small drives require protection from voltage sags, spikes, and phase loss. Installation is straightforward: the relay can be mounted on standard DIN rails, and its terminals are clearly labeled for easy wiring. The device operates efficiently without generating excessive heat, making it suitable for enclosed panels with limited ventilation. Users can integrate the LSA-H3P50YB into existing control systems, leveraging its solid‑state technology to reduce maintenance needs and improve overall system uptime. Whether retrofitting older equipment or designing new automation solutions, this relay provides a dependable safeguard against electrical disturbances.
