Description
TH-5DB Marine Breaker
Structure
The handle, operating mechanism, trip device, arc extinguishing device, and contact system of this circuit breaker are assembled in a plastic enclosure to form a single unit. Since the operation is "on" and "off" quickly, the contact wear is small and the service life is long. The trip device is adjusted and sealed before shipment, and its characteristics are not affected by unexpected changes. The two-pole and three-pole switches are internally equipped with linked trip devices, which will not cause circuit breaker accidents.
Reset instructions
When the circuit breaker trips due to a fault in the controlled circuit (overload or short circuit), the handle is in the middle position. When attempting to re-close (after determining the cause and resolving the fault), first move the operating handle to the "off" position to reset, and then close the circuit for operation.
