This one is an ITE/Siemens KB Dashpot for Switchgear. Dashpots on switchgear allow the overload trip to have time delay so breakers won’t open because of a current surge.
Excess current attracts the plunger causing it to go up against the viscose oil or silicone liquid through a the piston’s hole.
When it’s time to upgrade or replace your UVR Under-voltage device, BCS Switchgear and breaker service helps you sustain your existing IITE KB style breakers by upgrading active components matching current technologies.
