281-402 – WAGO

Overview

The WAGO 281-402 is a 4-position, insulated cross-connection jumper designed for efficient terminal block configuration. Its primary function is to bridge adjacent terminals, enabling rapid wiring consolidation and reducing point-to-point connections. A critical design consideration for such jumpers is ensuring robust mechanical integrity and reliable electrical contact under vibration and thermal cycling; however, users must be mindful of the maximum current rating to prevent overheating and potential failure, a common trade-off in high-density wiring solutions.
