[MITSUBISHI ELECTRIC] — UT/UN-SA Operating Coil Surge Absorber Units
Family ID: MEL-OPT-SA
Mitsubishi Electric UT-SA and UN-SA surge absorber units suppress noise generated when the operating coil current of MS-T/N contactors and relays is interrupted, protecting electronic circuits from malfunction and damage. One-touch mounting in the space below the coil terminals. Element types: varistor (peak voltage limiting), varistor with LED indicator, CR (high-frequency suppression, AC and DC coil types), and varistor plus CR combined. Voltage designations selected to match the operating circuit voltage. UL and CSA certified types available.
