1.About us

   We're the leading manufacturer specialized in designing and  manufacturing thermal overload relay in China with the experience  of more than 15 years,manufacturing according to the ISO9001 quality control system guidelines and IEC60947-4-1 standard. We help our customers develop the specical thermal overload relay as per their inquiries and OEM service offered.

2.About the product

   1).The  product   is mainly used in ac electromotor of AC 50Hz or 60Hz, voltage up to 690V, current up to 93A  for overload and phase failure protection,which is also combined with SC1 contactor to form electromagnetic starter.

   2).The product is of several functions,such as phase-failure protection,temperature compensation,tripping indicator and so on.

   3).Highly standard modular design is to reduce variety of parts and improve its reliability.

   4).The feature is compact constructure ,credible operation.

   5). The main components(expect those easily disable parts) can last as long as up to more than 30,000 hours.

   6).All key components are finished by precisely machining,accurately assembling, and finally tested and therefore high quality

is reached.
