There are 3 Robertshaw motor protectors. Two are part # 3433-036, model: MP33-1209. Additional information listed on the boxes are: Solid-state motor protector, cut-out 200 deg.f, cut-in 170 deg.f., 375 WA @ 208/240 Vac, automatic reset, replaces MP23-1036. The other one is part # 3450-002, model: MP50-1201. Additional information on this box is: Motor protector w/time delay and low voltage monitoring, 375 Va @ 208/240 Vac, resistance trip (cut-out) 13K OHMS, resistance reset (cut-in) 3.25K OHMS, time delay on break 2 minute (120 seconds), low voltage trip (cut-out) 170 Vac, low voltage reset (cut-in) 183 Vac, replaces Klixon/Texas instruments #'s: 3AA4-2, 3AA18-6 and 15AA1600c, replaces Copeland #'s: 071-0376-01, 071-0397-00, 071-0424-00 and 071-0441-00. Kind of long winded but that is all the information on the box. These appear to be new in the box but since these items have not been test, they are being sold as used and in "as is" condition. Not sure what type of motor they are for. There are some type of instructions included in each box.
Will ship Parcel Post since that appears to be the least expensive way. Hope this is OK.
Thanks for looking and have a great day!
