Littelfuse, Inc. Industrial Relays 460-200-SP

The 460-200-SP is a single-phase voltage monitoring relay designed to protect 190-240 V ac, 50*/60 Hz motors from damaging high and low voltage conditions. It features a fixed 4-second trip delay and an adjustable restart delay of 1-500 seconds for staggered motor starting. The relay uses a microcontroller-based circuit for continuous voltage monitoring and includes advanced LED indicators for diagnostics. It is mounted on a 35 mm DIN rail or via surface mounting with #6 or #8 screws, and has a polycarbonate enclosure rated IP20 and NEMA 1. Its output relay is rated for 10 A at 240 V ac and meets UL 508 standards with a hi-pot test of 2 × rated V + 1000 V for 1 minute. Operating temperature ranges from -40° to 70°C, and it complies with IEC 61000-4-2, IEC 61000-4-4, IEC 61000-4-5, and ANSI/IEEE C62.41 for ESD, fast transients, surge, and ring wave immunity.
