PSM socket modules PSM busbars The modular system facilitates basic configuration of the racks, thanks to a vertical support rail with single-/3-phase infeed. The various socket modules to supply the active components may be snap- fitted into the support rail. This can even be done whilst the system is operational, because the sup- port section is shock hazard-protected.
PSM socket modules The various modules, earthing pins, IEC 60 320 etc. may be inserted into the support rail in any combi- nation. This is easily achieved, even by non-electri- cians, thanks to the shock hazard protected plug & play system.

Technical specifications/benefits: ◾ Each socket module picks off a phase on the support rail, either from infeed A or from the redundant infeed B, depending on the direction of connection
◾ Single-/3-phase construction with a maximum current of 2 x (3 x 16 A)
◾ 3-phase redundant infeed supported ◾ The redundant circuit is completely separate from the 3 phases of the support rail
◾ Modules may be retrofitted whilst operational ◾ Modules may be equipped with integral overcur- rent protection, so that only the affected module is deactivated in the event of an excessively high current; the other modules remain operational
◾ Overvoltage protection may be integrated into the supply line
◾ Various modules also available with current measurement and switchable outputs
