Looking for expert on Motor Overload Relays

[padyakbud]

I am looking to hire an individual or company who has extensive experience in electrical repairs related to large motors.  I have a large 3 phase 50HP Sullair air compressor with a burned out Cutler-Hammer overload relay.  Ive been trying to source out this identical model to no success for the last few weeks.

I am now resigned to the direction of retrofitting the Cutler-Hammer with another brand available in the market.  This is a complex and highly specialized work our company does not have expertise on.  If someone has the expertise and experience to do this job, kindly call or txt me at 0927-780-9701.  This is an immediate job requirement.

sir baka pwede magawan ng paraan dito sa forum. post lang po ng picture para magawan ng paraan. usually po pag ganyan na ang capacity naglalagay kami ng bypass contactor sa overload relay during start-up... seconds lang po yon then mag-o-open na ang bypass contactor. 

Star Delta po ba connection o Across the line lang?

Thanks Tolits for the reply.  The Cutler-Hammer overload relays have a special feature wherein it has heat pack sensors.  Sourcing another brand will bypass this safety feature and I dont know how safe it would be to do it.  Even the compressor experts we have contacted recommend sourcing the original Cutler-Hammer brand instead of a retrofit because of this feature.  I have contacted the authorized Cutler-Hammer distributor in the Phlippines but it would take them 4 months to get it in because it is special daw.  Unfortunately I dont have the luxury of keeping the compressor down for that long and is looking for a compressor expert knowledgeable on this type of convertion.

i've been working with protection relays, baka may maitulong ako......

Background check muna ha....

Ano bang nangyari at yong OL relay ang nasunog? yong OL ralay lang ba ang nasunog o pati ang motor na pinoprotektahan nito?

Anong Model po ng Cutler-Hammer OL relay yan?

Wwwooopps parang OL thermal relay po pala yan....marami pong replacement nyan basta parehas lng ang ratings nito, try Schneider, Basler, Siemens, ABB etc etc....

sir lahat po ng overload relay ay may heater pack dahil yan po function ng OL. pag overload ihi-heat nya yong bi-metalic para mag-trip. kung may model number po kayo ng OL baka magawan pa ng paraan. marami pong brand as sir <')XXx< said. Pwera na lang kung microcontroller controlled ang OL ninyo like sa compressor namin na Atlas Copco kelangan talaga palitan ng same brand.
