Allen-Bradley 1492-WM4-B | 20A Miniature Terminal Block, Blue, 300V, 4mm² Screw Connection Lot of 48

The 1492-WM4-B is a single-circuit, feed-through terminal block that offers a step up in wire capacity from the WM3 series. The Blue housing is the industrial standard for identifying Neutral conductors or Intrinsically Safe (IS) wiring. Despite its miniature size, it maintains a robust screw-clamp mechanism that provides the high contact force necessary for vibration-prone environments.
