Reading the manual may seem like a daunting task, but it's essential to getting the most out of your Tomzn TOVPD160EC. Here are just a few reasons why: : The first button (Power) allows you to
The device uses standard top-inlet, bottom-outlet logic for DIN-rail distribution boards. Incorrect wiring can instantly destroy the internal sensing circuit.
This unit does not provide short-circuit protection. You must install a standard Miniature Circuit Breaker (MCB) upstream to handle short-circuit faults. Troubleshooting & Advanced Features Checking the Last Fault Tripping Reason
