CONTREL继电器说明
The is an earth leakage protection device , which manitaining its ample scope of settings, both for current and time delay, it has been built in a flush mounting enclosure DIN 48x48mm with a reduced depth of 72mm, including wiring terminals.
This allows to reduce the over all dimensions to a minimu, in those applications in which the space is critical, like in MCC’s.
The present ELR, so as the others of the ELR’s families, has a built-in filter,at the input circuits, which brings it practically immune to external distortions. It is possible to program the tripping current (25mA ÷ 25 A), the tripping time delay (0,02 ÷ 5 sec.,) and the working mode of the reset (automatic or manual), at its front plate.
The ELR-7 has a microswitch to select the working mode of the end relay, normally de-energized, whilst at rest (no tripped condition) or normally energized ( fail safe).
On top of the above, it also has 2 change-over separated and a transparent front cover for protection. Its removable wiring terminals rends it very easy to install.
这是一种漏电保护装置，它可充分利用其在电流和时间延迟方面的设置范围，它内置于DIN 48x48mm的嵌入式安装外壳中，其深度减少了72mm，包括接线端子。
在空间要求严格的应用中（例如在MCC中），这可以将整体尺寸减小到最小。
与其他ELR系列产品一样，目前的ELR在输入电路上也具有内置滤波器，因此几乎不受外部失真的影响。可以在其前面板上编程跳闸电流（25mA÷25 A），跳闸时间延迟（0.02÷5秒）和复位的工作模式（自动或手动）。
ELR-7带有一个微动开关，用于选择终端继电器的工作模式，该模式通常是在断电，静止（无跳闸状态）或正常通电（故障保护）的情况下进行的。
除此之外，它还具有2个单独的转换开关和一个透明的用于保护的前盖。其可拆卸的接线端子使安装非常容易。
