35mm Motor Protection Relay , OEM ODM Generator Protection Relay Din Rail Installation
Distribution board in middle/small vessel mainly use frame-type circuit breaker as generator's protection switch, have shortage of expensive cost, big volume, heavy and difficult to adjust, etc.
WD-DB-A is a multi-functional protection equipment for marine, widely used in kinds of type/power generator group, only need input generator's power and curcuit's transformer, protection can set data of "pre-alarm" "long-time delay", "short time delay" according to requirements.
Acting time can also be adjusted, LED indicate voltage, current and lasting time.
