Product details

The 3RF3900-2TB88 is a replacement control connector for the Siemens 3RF30/31/32/33/34 series of solid-state switching devices with spring-loaded connection systems. It provides two clamping points per contact and carries the identifying markings A1 and A2 on a black body. This connector is the service spare for the control terminal block on those 3RF spring-loaded units — if a clamp gets damaged or the wire entry wears, this is the direct swap without replacing the whole switching device.
