Motor; stream (std. tensioned replenishment at sea method) end item identification, three phase, kit contains 3matched motor-winding thermostats; thermost ats are tied in place on the end turns of appropriate winding bundles, one to each phase or buried in the windings during motor rewind; are connected in series between the starter coil and its power supply; supplements conventional current overload relays in magnetic starters, protects against blocked ventilation, high ambient temperatures, single-phasing, and dangerous running overloads; operating temperature: 140 degrees c special features

A protective device specifically designed to prevent damage to an electrical motor due to failure of the motor to start, severe overloading of short duration, too frequent starting, high ambient temperature, high or low circuit voltages, failure of ventilation or any combination thereof. It is designed to be either automatically or manually reset. Excludes:circuit breakey; switch (1), thermostatic; heater, thermal release; and relay (1), thermal.
