Specs At A Glance

Good To Know

Q: Does this voltage regulator work with all Thermo King SB-210 units? A: It fits SB-210, SB-200, SB-210+, 30, and 50 models, but verify your unit's serial number to confirm exact compatibility.

Q: What happens if I ignore a faulty voltage regulator? A: A failing regulator can overcharge or undercharge the battery, leading to alternator damage or unexpected shutdowns of your refrigeration system.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
