Ultra-High Energy Varistor for Extra-Heavy Surge Protection (34S K / KJ Series)
The MOV 34S Series Metal Oxide Varistors (K and KJ types) are oversized heavy-duty surge protection components built for the harshest electrical environments, including power grids, surge arrestor boxes, and lightning-prone AC lines. With exceptional energy absorption and structural robustness, the KJ version includes thicker leads and reinforced solder pins for enhanced reliability. This series covers a wide range of varistor voltages (180V–1120V), ensuring performance and international standard compatibility.
MOV 34S Series is suitable for ultra-high surge protection in:
