RFN382300 - T/O RELAY 17-23A MAN/AUTO
MPN: RFN382300
Why Choose the RFN382300?
Designed for dependable motor protection, the Lovato RFN382300 thermal overload relay safeguards three-phase loads in the 17…23 A range. This non phase failure / non single‑phase sensitive device offers manual or automatic resetting and three-pole protection. For fast, tidy assembly, the RFN382300 mounts directly onto BF09…BF38 BF series contactors, helping panel builders and MRO teams streamline installations without additional adapters.
Engineered to international standards, this relay provides IP20 frontal protection, Ui 690 V and 6 kV impulse withstand for robust performance. It operates from −25 to 60 °C and up to 3000 m altitude, with a three-pole design for three-phase circuits. Conformity to IEC/EN 60947-1 and 60947-4-1, plus UL508 and CSA C22.2 n° 14, supports confident specification in industrial control panels.
