Is it recommended to use 2NO/2NC LC1D188** for changeover application.

How can we help you today?

2NO/2NC LC1D188** contactors are design for 2 speed motor applications. Source change over system must be constructed using 2 different contactors mechanically and electrically interlocked to avoid any issue during source change over operation

So it is not recommended to use LC1D188** contactor for changeover application because using 2NO/2NC contactor in source change over application will lead to contactor issue
