Industrial U037 Contactor

Type U037 Allenwest Contactor is a heavy-duty industrial motor-contactor designed to switch three-phase motors in control panels, switchgear, and industrial drive systems. The U037 family is available from Allenwest in variants with coil voltages of 240–250 VAC and 110–115 VAC, both in 50 Hz configurations, reflecting compatibility with common control circuits and interface requirements. A typical rating associated with U037 listings is approximately 37 kW at 415 V when operated at 50 Hz, indicating suitability for mid-size motor loads in industrial facilities. In practice, the U037 is used as the primary switching element in motor starters and industrial drive architectures, typically paired with auxiliary contacts and overload protection to enable safe remote or automatic motor control.
