Hitachi's Electromagnetic Contactors & Switches (up to 660 VAC) catalog presents the new HS series, offering power savings, miniaturization, and improved inching performance with high reliability, voltage stability, and standards compliance. The H series provides standard contactors with status indicators, noiseless coils, and surge protection. Thermal overload relays (1E/2E) ensure compact, cost-effective motor protection, including phase-failure detection. Specialized DC, latched contactors, and automatic star-delta starters are also detailed for diverse industrial control.
