Phase failure and phase sequence protective relay for three-phase systems with phase loss, phase sequence, imbalance, overvoltage and undervoltage protection.
It is mainly composed of column contact regulator, sampling, protection, control circuit, low-speed synchronous motor mechanism, and compensation transformer.
Uses digital integrated circuit sampling control system to control electromagnetic relay and change auto-transformer tap for stable output voltage. Ca...
NF2 load switch for safe isolation and manual switching. 16A-1250A, up to 690V AC. Padlockable in OFF position. For distribution boards, motor circuits.
