B6 brake
B6 power-off, fail safe hold brake is a special NEMA23 installation version designed for direct installation on the front of EA057A motors without the need for an adapter. It has a NEMA23 flange and larger half inch input and output shafts. When the motor and brake are powered off, B5 is designed to keep the load stationary.
