Multi - Function Motor Switching Relay , Electric Motor Relay Adjusted Acting Time

1. Products Description:

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.

2. Technical Parameters

3. Technical Symbol:

"I" Current: Display the biggest phase current, connect any phase to start to work;

"U" Voltage: Display phase voltage to generator;

"U" < under voltage: Phase voltage less than preset value;

"I" ≈ Pre-alarm LED: ;Load current over preset value;

"I" > Long-time delay LED: Load current over preset value;

"I" < Short-time delay LED: Load current over preset value.
