Intelligent Motor Protection Relay WDB-1FMT CE / CCC Cetification 220VAC

The ideal motor protector is not the most functional, nor is it the most advanced, but should be the most practical. So what is practical? The utility should meet the reliability, economy, convenience and other factors, and have a high performance-cost ratio. So what is reliable? The reliability must first meet the reliability of the function. For example, the overcurrent and phase-off functions must be able to reliably perform overcurrent and phase failure in various applications, processes, and methods. Second, its own reliability (since the protector is to protect others, in particular, should have high reliability) must have a variety of harsh environments, adaptive stability, durability. Economical: Adopt advanced design, reasonable structure, specialization, large-scale production, reduce product cost, bring high economic benefits to users. Convenience: It must be as simple and convenient as possible in terms of installation, use, adjustment, and wiring.
