What Zotup does
ZOTUP S.r.l. is an Italian manufacturer of surge protective devices (SPDs) founded in 1986 and headquartered in Ranica (Bergamo), Italy. The company designs and produces varistor-based SPDs built on its proprietary ZOTUPLIMITER platform, covering alternating current (Type 1+2), LED lighting, photovoltaic, signal/telecommunication, data transmission, and medium/high voltage applications. Core technical differentiators include five international patents (2016–2023) covering an integrated fuse function, a progressive degradation indicator, blade disconnect, plasma discharge disconnect, and arched deionization chamber, with sub-25ns response time, No Follow Current (NFC) technology, high temporary overvoltage (TOV) withstand capability, and Pollution Degree 3 rating for harsh environments.
The business operates a dual-channel go-to-market: direct field sales with specialized technical support targeting enterprise and critical-infrastructure customers (data centers, industrial, utilities, telecommunications), complemented by a regional sales agent and distributor network across Italy, Turkey, India, and the UAE. Revenue is generated primarily through hardware product sales, with secondary revenue from professional services including technical training seminars and specification consultation. Pricing is quote-based and not publicly disclosed, with multi-year enterprise contracts and a distributor-driven model for mid-market and installer channels; the company also operates a self-serve online configurator (webapp.zotup.it) and publishes a comprehensive Designer's Manual as technical-marketing infrastructure. The company is family-owned (CEO Gianfranco D'Ippolito, Board Member Andrea D'Ippolito), holds KEMA-KEUR and IEC/EN compliance certifications, and serves a reference base of 100+ enterprise projects including Amazon, Sony, Vantage Data Centers, Aruba, Airtel Nxtra, NSE India, Poste Italiane, Enel, Italcementi, and Solvay.
