Scope of Application
This product is suitable for use in stations, ports, public buildings, and especially in motor group control systems and local control equipment for metallurgical and light industrial production lines. When equipped with appropriate interfaces, it can be integrated with PLCs (Programmable Logic Controllers) or microprocessors to form automated power distribution control systems. It is fully capable of meeting the requirements of centralized control systems in chemical industries.

Ambient Conditions:
■ Altitude not exceeding 2000m.
