LiftMaster K71-B240H Internal Brake Solenoid with Cable 240V for H Hoist Operators
The LiftMaster K71-B240H is a 240V internal brake solenoid with cable for select LiftMaster industrial-duty hoist commercial door operators. It is part of the H-model brake system where the solenoid, cable, and internal brake mechanism work together to release the brake during motor operation and hold the load when the operator stops.
This part is commonly listed for Model H industrial-duty hoist operators manufactured after 2005. It appears in H-model parts breakdowns alongside other voltage-specific internal brake solenoids with cable, including the 120V K71-B120H and 575V K71-B575H. Because the suffix and voltage both matter, it should not be selected solely by appearance or by the word hoist in a listing.
Related numbers include 716203230, 71-B240H, and 71B240H. Some listings describe it as 220V while others use 240V. In the product copy, it is safest to treat it as the K71-B240H 240V family and confirm against the operator label and LiftMaster parts diagram before installation.
