 The switch is designed for use in an environment with a degree 

of contamination 3 (conductive contamination or dry, non-conductive 
contamination that becomes conductive due to the expected condensation 
is possible). The environment is non-explosive, does not contain aggressive 
gases and vapors in concentrations that destroy metals and insulation, is not 
saturated with conductive dust and water vapor.

Technical data

The switch of VA44 type is available with combined disconnectors (thermal 

and electromagnetic).

 The technical data of the switch are given in table 1.
The response characteristic of the thermal release is given in table 2.
 The time-current characteristics of the switch are shown in figures 1–4.
The electrical circuit of the switch is shown in figure 5.
The overall dimensions of the switch are shown in figures 6–9.
For the switch, it is possible to install additional devices presented in table 3.
The template for marking the mounting panel is shown in figure 17.
Additional technical data, as well as the overall dimensions of the tips and 

extended terminals are shown in figures 12–16.

Completeness

The completeness of the switch is shown in table 4.

Installation and operation rules

The operation of the switch should be carried out in accordance with the 

current requirements of the rules on electrical safety, as well as with other 
regulatory and technical documentation regulating the operation, commissioning 
and repair of electrical equipment.

The switches are installed on a metal panel with a thickness of at least 3 mm 

or on a panel made of insulating material with a thickness of at least 6 mm and 
fixed with screws included in the delivery package.

 The normal operating position of the switches in space is on the vertical 

plane with pins 1, 3, 5 up, it is allowed to be installed on a vertical plane with pins 
1, 3, 5 rotated left or right by 90

°

.

The switches allow the supply of voltage from the power supply both from 

terminals 1, 3, 5, and from terminals 2, 4, 6.
