To stop your three-phase motor from choking up, turn to this thermal overload relay from Schneider Electric. It helps to prevent a motor from drawing too much current, which can otherwise cause overheating and damage. The handy unit also picks up on unbalanced loads and phase failure, so it's quick to step in if there's a power supply problem. An adjustment dial makes it a breeze to manually set your thermal protection range between 1 and 1.6A. Once you've chosen your settings, you can lock the device by sealing its transparent cover, to eliminate the risk of tampering.
