surge arresters MOV metal oxide varistor for semiconductor D30×30 Metal oxide varistor
MOV Blocks is a ceramic semiconductor element made of zinc oxide as the main material, its resistance value changes with the change of applied voltage, is the core component of metal oxide arrester, and its quality directly determines the performance of arrester. Our company's metal oxide varistors have the characteristics of strong galvanizing ability, high protection performance, good nonlinear characteristics, exquisite appearance and diverse specifications. The common voltage gradient range is 200~230V/mm. Its diameter and height can be flexibly determined according to customer requirements. The maximum diameter of the varistor is 138 mm, and the maximum height is 41 mm.
Features
Excellent non-linear characteristics
Compliance with IEC /IEEE (ANSI) standard
High discharge current capability
High energy absorb capability
Application
Metal oxide varistor is currently the most common voltage clamping device and can be used for a variety of voltages and currents.
Metal oxide varistors are very effective at absorbing short-term voltage transients and have higher energy handling capabilities.
Like ordinary varistors, metal oxide varistors start conducting at a certain voltage and stop conducting when the voltage drops below a threshold voltage.
