HRN Voltage Monitoring Relays

ELKO EP HRN Voltage Monitoring Relays are available with DPDT or SPDT relay contacts and contact current ratings of 5A, 8A, 13A, or 16A. These relays are offered in one- and three-phase options with silver, silver-tin, or silver-nickel contact material. The HRN series features widths of 17.6mm, 36mm, and 52mm and several lengths ranging from 64mm to 66.5mm. Engineers can choose from a wide variety of relays, including multifunction voltage monitoring relays, multifunction voltage/frequency monitoring relays, and voltage monitoring relays with selectable range, adjustable levels, and fixed levels. Typical applications for ELKO EP HRN Voltage Monitoring Relays include appliances, switchboards, microcontroller-based systems, and sensitive equipment.
