The 90 AM range, in addition to auxiliaries common for the all circuit breakers, comprises many modular accessories for the protection, command, programming, measurement and signalling in electrical systems.
APPLICATIONS: used in order to have a better heat dissipation when more contactors/relay are installed in adjiacent position. SUGGESTIONS FOR AN OPTIMAL HEAT DISSIPATION: - Operating temperature up to 40°C: no limitations. - Operating temperature between 40°C and 55°C: No limitation for AC coils, 1 spacer every 3 adjacent relays with DC coils: - Operating temperature between 55°C and 70°C: 1 spacer every 3 adjacent relays with AC coils. It is not possible the adjacent installation of relay with DC coil.
