The handle of the breaker can be placed in three positions, which represent CLOSED, OPEN and FREE TRIP individually. When the handle is in the position of FREE TRIP, it should be turned in direction of OPEN at this moment. Then the breaker can be re-latched and closed. The user should conform to the regulations of the storage and application. Within months after delivery from the manufacturer, if the product can not work properly or be damaged due to quality defect, the manufacturer is responsible for changing or repairing without charge. Ordering Notice The model, specification and order quantity of the breaker should be noted. When using undervoltage release, shunt release or motor operator, please give clear indication of operation voltage or the value of control power voltage. For example: NDM-5L with undervoltage release and single auxiliary contact; rear connection type; Rated current 0A; Control voltage AC V; Quantity: PCS. Then you can order as following: NDM-5L7-0A ACV PCS It should be declared, when the ambient temperature meets the following situation: Upper limit over + or lower limited below
