Introduction<\/strong><\/h2>\n
\n

\u00a0 \u00a0 Le <\/span>Commutation de contr\u00f4le et de protection, Protecteur de moteur <\/a>Le produit poss\u00e8de des fonctions telles que la surtension, la sous-tension, la surcharge, le court-circuit, le rotor bloqu\u00e9, le d\u00e9s\u00e9quilibre triphas\u00e9, la surchauffe, les fuites, la communication, etc. La conception du logiciel est conviviale, avec un affichage direct sur trois lignes, et les fonctions du produit sont faciles \u00e0 \u00e9tendre. Actuellement, il s'agit de l'interrupteur de contr\u00f4le et de protection le plus complet dans la fonction de protection des \u00e9quipements \u00e9lectriques. <\/span>protecteurs<\/a>.<\/span><\/p>\n

\u00a0Caract\u00e9ristiques du produit<\/strong><\/h2>\n
\n

1. Extension des fonctions : Protection contre la temp\u00e9rature et les fuites, tant que des accessoires externes sont connect\u00e9s, les fonctions de protection requises peuvent \u00eatre ajout\u00e9es.<\/p>\n

2. Affichage num\u00e9rique \u00e0 trois rang\u00e9es de tubes, affichage intuitif en temps r\u00e9el des param\u00e8tres de tension, de courant, de fuite et de temp\u00e9rature.<\/p>\n

3. Large plage de r\u00e9glage du courant de protection :<\/p>\n\n\n\n\n\n\n\n\n\n
