2361-SPB01A

The 2361-SPB01A assembly is a snubber assembly that is available in the spare parts catalog of the 2361 series of devices made by Allen-Bradley. This series covers digital DC drives and motor control centers for drive systems and the spare parts catalog is made to provide users with parts that enable them to repair and keep using their drives as a complete system for as long as possible. This specific snubber assembly provides the snubbers that are needed so that the drive can operate properly. The Allen-Bradley 2361-SPB01A snubber assembly provides protection and performance enhancements to the main drive. Snubber circuits have different purposes and one of the most common applications for them is power dissipation applications in electronic power switching networks. The functioning of a snubber consists of switching the voltage amplitude, which translates to a reduction in the power dissipation.

The Allen-Bradley 2361-SPB01A snubber assembly provides different snubbers that in turn provide different branch circuit protection. Other important functions of snubbers are reducing the total switching losses and since these snubbers have the ability to dampen voltage, they also reduce EMI. The Allen-Bradley 2361-SPB01A snubber assembly is considered to be a minor assembly and it is fully compatible with DC units with a current rating of 1250 to 1650 Amps. Snubbers are installed in parallel with the SCR and they operate alongside the cell reactors to provide adequate voltage suppression once the SCR has been switched off. This snubber is an electronic part that needs to be installed by a qualified  technician who is familiar with the whole system, including the other spare parts from the same catalog.
