How it works and how to install it
The LA4-2H button operates via direct manual action: pressing the green button closes the circuit and starts the connected equipment, while pressing the red button opens the circuit and stops the motor — both returning automatically to their initial position upon release. Installation involves feeding cables through the gland hole at the top of the casing, connecting wires to the screw terminals inside, and securing the box to the desired surface using the four existing mounting points. It requires no special tools and can be installed by anyone with basic electrical knowledge.
Frequently asked questions
Does this button work with a 380V three-phase motor?
Yes, the LA4-2H button supports AC voltages between 220V and 380V, making it compatible with both single-phase and three-phase circuits, within the 5A current limit.
What does a momentary button mean and why does it matter?
A momentary button automatically returns to its initial position after you release it, unlike a switch that remains locked. This feature prevents accidental equipment startup and is a standard requirement in industrial applications.
Can this button be mounted outdoors or in wet environments?
The casing is made of ABS plastic with a cable gland entry, however, the product does not have a specified certified IP rating, so it is recommended for use in covered areas or protected from direct moisture and splashing.
