Down-sizing

  • MS-T series provide industries smallest general purpose Magnetic Contactor in its class, customers are able to more easily down-size their boards than ever before

Standardization

  • New integrated terminal covers (for 10A to 50A frame) – a terminal cover is included as standard part in contactor
  • Reduce coil inventory by up to 50% (for 10A to 35A frame) – the 14 types of operation coil ratings available with the MS-N Series have been halved to 8 types with that increasing the applicable voltage range. Therefore, customers can reduce their inventory

Safety and Quality

  • Terminal cover with finger protection function (for 10A to 50A frame)
  • A light touch (for all framesize) – MS-T Series’ auxiliary contacts can operate with load as light as 20V 3mA making it suitable for direct control/operation from a PLC output.

Global Standards

  • Compiles with main International Standards : IEC, JIS, EN, TUV, GB, UL, CE, CCC
