The MC50 is a miniature series single pole free standing compact contactor which is sealed to IP67. The MC50 has been designed to fill the gap between 30 Ampere relays and 80 Ampere contactors and is suitable for switching resistive and inductive loads up to 48V DC.  Typical applications are small traction motors, hydraulic power packs and engine starter motors for golf cars and garden machinery.

The MC50 features single pole double breaking contacts with silver alloy tips which are weld resistant, hard wearing and have excellent conductivity. The MC50 has M8 stud main terminals with the option of M6, and the coil terminals are 6.3mm spades. It can be side or base mounted with the included brackets.
