Allen-Bradley 1492-L3 | 25A Spring-Clamp Terminal Block, Gray, 600V, 2.5mm² Feed-Through Lot of 62

The 1492-L3 is a single-circuit terminal block that utilizes spring-cage technology instead of traditional screws. This design is highly favored in environments with high vibration (such as mobile machinery or transit) because the spring maintains constant pressure on the wire, preventing it from backing out over time. It features a "front-entry" design where the screwdriver and wire enter from the same direction, making it much easier to wire in tight spaces.
