Hafler DH-500 thermal circuit breaker needed
Hello all,
I'm trying to find a replacement thermal circuit breaker (Schematic location TB1 and TB2) for a Hafler DH-500 the part number is SF-024 in the earlier manual, or 332002 in the later manual. The part is no longer available from Hafler. The original is made by Elmwood Sensor, a division of Honeywell and is a 2450 series (the number is molded into the plastic on the top of the sensor). Other lettering around the side of the defective one is "87-232 L167 80/K", where 87-232 is likely the date code (232nd day of 1987), no idea about the L167, and 80/K the temperature where it trips. I've contacted Elmwood and the part is still available, with a $750 minimum order, so that is not one of my choices. I believe the DH-120, DH-200, DH-220 and DH-500 all use the same part. Does anyone have a parts unit that might have a good thermal circuit breaker that they would be willing to part with? (Please note that on the DH-500 there is also a thermal sensor to turn on the fan, which is NOT a substitute.) Thanks for your time, Tim Schwartz Bristol Electronics |
