Description
MR30-FB CONN DC SUPPLY FEMALE 3 PIN BRASS SOLDER — BOLTON SKU 66456.
About the MR30-FB 3-Pin Female DC Connector, Solder
The MR30-FB DC power connector is an AMASS three-pin female connector from the MR30 series, supplied with solder cups for direct wire attachment. Contacts are gold-plated brass and the insulator body is nylon with a UL94 V-0 flame rating. AMASS publishes a continuous current rating of 15 A with a peak capacity of 30 A, a rated voltage of 500 V DC, and a durability of 1,000 mating cycles. Recommended cable is 18 AWG with an overall diameter of about 2.8 mm, and the recommended soldering condition is 400 °C for three seconds. The three-pole keyed arrangement is the format normally used between a brushless motor and its speed controller: the three phases sit in one housing that cannot be mated in the wrong orientation, which removes the loose individual bullet connectors and heatshrink that otherwise carry the motor phases. The connector is listed as meeting CE and UL requirements.

Typical applications
Three-pin MR30 connectors join brushless motors to electronic speed controllers on multirotor and fixed-wing UAV airframes, where a compact keyed joint saves weight and assembly time against separate bullet connectors. The 15 A continuous rating covers small and mid-size propulsion units and accessory power runs. Solder cups allow a damaged motor lead to be re-terminated without crimp tooling.
