Overview

The WEG MPW100-3-U100 (SKU: MPW100-3-U100) is a UL Type-E manual motor protector designed for 3-phase motor applications. It integrates four NEC-required functions: motor disconnect, branch circuit protection, motor controller, and overload protection in a single compact unit. Rated for 80-100A thermal setting, this protector supports motor loads up to 75 HP at 460V and 100 HP at 575V. It delivers 50kA short-circuit interruption capacity at 480V and 10kA at 600V, ensuring reliable protection against faults. Phase failure sensitivity protection prevents damage from single-phasing, while overload trip class 10 provides precise thermal overload response. The unit complies with IEC 60947-1/-4-1, EN 60947-1/-4-1, UL 508, CSA C.22.2/14, and VDE 0660/102 standards. With a rated impulse voltage of 6kV and pollution degree 3, it operates reliably in industrial environments up to 2,000m altitude. Its utilization categories include IEC 60947-2 (Motor Protector: A) and IEC 60947-4-1 (Motor Starter: AC-3). The WEG MPW100-3-U100 is ideal for panel-mounted applications requiring space-efficient motor protection with high interrupt ratings.
