TPS-ESB-01-25A 25A AC-Inrush Current Limiter

The TPS-ESB-01-25A is a high-capacity 25A active inrush current limiter designed for robust 230VAC single-phase applications, providing critical starting current limiting for heavy-duty equipment. This sophisticated inrush current limiter circuit employs an integrated bypass relay, offering a more reliable and efficient solution compared to basic NTC thermistors by eliminating power loss after the startup phase. It is engineered to clamp high inrush currents, limiting peaks to 45A for a controlled duration of 100-500ms. This provides essential protection for systems with significant inductive loads such as large motors and isolating transformers, as well as capacitive loads, preventing damage and nuisance tripping. Housed in a compact, DIN-rail mountable IP20 case with screw terminals for AWG13-11 wires, it ensures easy integration into industrial control panels. By effectively managing inrush currents, it allows for the use of smaller cable cross-sections and faster-acting circuit breakers, optimizing system design and cost.
