➀ Bourns' IsoMOV surge protectors combining MOV and GDT technologies received IEC 61051-2 certification, validating their hybrid design for enhanced reliability;

➁ The devices feature leakage current blocking via GDT, voltage ranges up to 555VAC/745VDC, and robust surge handling (up to 15kA pulses) with low capacitance;

➂ Certified for -40°C to +125°C operation, these components address premature MOV degradation while maintaining protection post-leakage increase.
