[Temperature relay]ABR19-S7 Three phase thermal protector

2026-6-11 17:28:14

Working principle of ABR19-S7 three-phase thermal protector:
The operation of the disc shaped thermal bimetallic jump action usually closes the contact system and is sensitive to both temperature and current. When used appropriately, the protector will shut down the motor or equipment when the temperature exceeds the maximum safety standard due to overload or stalling (locking the rotating shaft). The motor needs to cut off the force, and the shorter the time, the better the current operation.
Purpose:
ABR19-S7 three-phase thermal protector motor protector is suitable for overheat and overload protection of motors, electric fans, submersible electric pumps, various types of electric pumps, agricultural equipment, air compressors, and instruments.
