Decoupler The decoupler on the HUBMO is designed for easy locking. It can be locked in the coupled position to ensure the motor is always at the ready if called on for remote operation, or it can be locked in the decoupled position so that the motor cannot operate the switch. The decoupler can be used to prevent switch operation for lock-out/ tag-out during maintenance of substation equipment.

Overload Protection The circuitry is designed specifically to cut power to the motor prior to damaging the motor operator. Thermal overload relays protect the mechanism from mechanical damage while a standard resettable breaker protects the electrical components. These breakers can be replaced with fuses at the request of the customer.

Manual Operator A manual operation handle is provided with each motor operator to allow adjustment or operation during a substation outage. The manual drive cover is electrically interlocked with the motor operator to prevent electrical operation when the manual operator is in use.

Custom Configurations Available Whether the customer is doing a unique installation to retrofit existing equipment, or installing a new standard configuration, the HUBMO is customizable to fit the customer’s specific needs. For configurations not listed; consult the factory.
