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. ## Lifecycle and compliance status RoHS compliance is confirmed effective 15 January 2024, and the manufacturer provides REACH Article 33 duty-to-inform documentation per the current candidate list.","metaTitle":"3RF3900-2TB88 replacement control connector, 3RF30/31/32/33/","metaDescription":"Replacement control connector for 3RF30/31/32/33/34 spring-loaded system.
