CITEL Surge Protection Devices (SPD) – General Overview
CITEL is a global leader in surge protection technology, with over 80 years of specialization in protecting electrical and electronic systems from transient overvoltages caused by lightning, switching operations, and grid disturbances. Their SPDs are engineered for AC power, DC systems, photovoltaics, LED lighting, telecom, and RF applications, and are fully compliant with IEC 61643-11, EN 61643-11, and UL standards.
CITEL’s proprietary VG Technology—based on advanced gas discharge tubes—offers enhanced performance against temporary overvoltages (TOV), making their devices ideal for demanding industrial and infrastructure environments.
