ET series is a continuation of the rugged single pole E and ES series with the addition of up to 6 poles (or more on special order).  This compact series is open style, with high momentary current capabilities.  Air insulated; no interrupting ratings are assigned, however, continuous currents range from 1 amp to 50 amps. Multipole ET series relays are useful for high voltage polarity reversing, multiple-load grouping, or safety grounding.  These are used in applications where it is desirable that all contacts be controlled from a single actuator.
