ST750 & ST755 Series

Marathon Special Products has been an industry leader in electrical/electronic components designed for circuit protection and connection applications for over 60 years.

We are pleased to introduce our new Motor Terminal Blocks. The new motor blocks provide a systematic method to wire electrical motors in the motor's junction box and allow for circuit management.

These blocks allow for much easier circuit testing and motor replacement over the traditional method of bolts, nuts and insulation. The motor terminal block links can be assembled for either wye or delta wiring configurations.
