Product Details

1. Product Overview

WEA100L-2 is a KSB three-phase asynchronous motor built to IEC frame 100L with 2 poles, rated 3 kW, about 2900 r/min at 50 Hz, efficiency class IE2. Its KSB article number is 3700112030.

This motor drives KSB pump sets and AMRI-KSB valve actuators, with a compact design and reliable operation. By IEC naming: 100 = frame (100 mm shaft height), L = long lamination, -2 = 2 poles. Exact voltage, protection and mounting (B3/B5/B35) should be confirmed from the nameplate.
