The plugboard has wedge-shaped plug insulators.Guide rods ensure that the prongs and plug insulatorsAlstom to perfect the technology, first introduced by GRSnearly 70 years ago. Today, Alstom relays are considered to make proper contact. Registration plates prevent improperbe the standard in the industry. Available in a wide range of installation of non-compatible relays to a plugboard. Sometypes and configurations, Alstom relays improve reliability, Type B relays are energized by DC voltage, others by AC voltage.They are designed to meet the important requirementsreduce maintenance and maximize operating life. They maybe rack-installed in equipment rooms, wayside cases or housings.Alstom Type B Vital Circuit Relays are available in two A vital Type B relay is designed so that the probability of itsof safety, reliability, low maintenance and long operating life.sizes – B1 and B2.
