Spring Loaded Terminal Block is designed to be inherently resistant to vibrations in normal applications. The Block has the feature that vibrations can arise due to vibration affected installation sites, such as installations in and around mines, proximity to heavy machine shop, forging/ die casting shops, cement/ steel plants machinery, and textile machines. The Block is used in power projects, power distribution centres, motor control centres and relay control panels. The Spring Loaded Terminal Block has the feature that the spring is assembled under compression, so that it engages firmly with the contact clamp.
