The TPS-ESB-01-25A is a 25 A active AC inrush current limiter designed for 230 VAC single-phase industrial installations. It provides controlled suppression of start-up currents using an IC-based limiting circuit and an integrated bypass relay to remove continuous power dissipation after the inrush period. The unit is optimised for DIN-rail mounting and straightforward integration into control panels where protection from excessive inrush is required.
Key features- 25 A rated current suitable for demanding start-up conditions.
- Advanced IC-based electronic limiting with integrated bypass relay for higher efficiency and improved longevity compared with NTC thermistors.
- Limits peak inrush up to 45 A for approximately 100–500 ms to protect downstream components and avoid nuisance tripping.
- Compact DIN-rail form factor for TS 35/7.5 or TS 35/15 installation.
- Durable screw terminal connections accepting AWG13–AWG11 (2.6–4.2 mm²) conductors.
- Wide operating range: -40 °C to 70 °C, up to 95% RH non‑condensing, altitude up to 2000 m.
- Compliance and certifications referenced: EN60950-1, EN61000-6-2, EN61000-6-3; CE, RoHS; additional listings (UL, WEEE, UKCA) referenced in documentation.
