TB, RB
Purpose:
Tire box (TB) is used to connect main AC 50Hz voltage of 380V (a network with isolated neutral) or 380/220V (a network with deafly earthed neutral) and current consumption of less than 250A.
Power box (PB) is designed to power mobile units (connected via outlet) AC 50Hz voltage of 380V (a network with isolated neutral) or 380/220V (a network with deafly earthed neutral) and current consumption of no more than 160A. Complete with tire box TB - power box PB can form railway box (RB) spans or drop box. The automatic switch installed in the box of the power YAS provides prompt switching on and off of the consumer and its protection against short-circuit current and overload. The rated current of the thermal release switch is specified when ordering.
A tire box in an Assembly with power boxes form assemblies:
