Automatic switch PSR-463-AUTO
The automatic switch is used for automatic and manual switching between two 3-phase supply lines or, for example, a supply line and a generator. Supported current up to 63A.
Operation:
The PSR-463-AUTO automatically switches the power supply between the main and auxiliary mains, e.g. between two supply lines or between a supply line and a generator, ensuring continuity of equipment operation. It is designed for operation on AC 50/60 Hz networks with a voltage of 230/400 V. It can handle currents up to 63 A.
-
Independent control system and execution mechanism.
-
Mechanical interlock protection to prevent simultaneous switching on of both power sources.
-
With extensive functionality:
-
Control of an external generator;
-
Operation with fire switches;
-
