MS-T Series contactors - 9-105A (AC-3)

Exceed your expectations

Down-sizing
MS-T series provide industries smallest general purpose Magnetic Contactor in its class (e.g. 10A frame model is over 16% smaller as compared to its class in MS-N series). This allows customers 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
