SIBA 2063432.700 DIN110 Semiconductor Fuse DIN110

The SIBA SQB3 700A 690V semiconductor fuse in the DIN-110 footprint (Article 2063432) is a high-current protection device designed for power semiconductor loads in AC circuits up to 690 V IEC / 700 V UL. This 110 mm DIN version, part of SIBA’s SQB3 family, provides a robust enclosure tailored to industrial protection schemes and is configured with a fitting for a microswitch to support external signaling of the fuse status. The 2063432.700 variant carries a nominal current rating of 700 A and is intended for use in applications where reliable interruption is required in fault conditions within the 690–700 V range. The DIN-110 size designation identifies the body length and mounting envelope, ensuring compatibility with standard bases and cabling arrangements used for SQB3 devices. With the microswitch fitting option, technicians can implement external signaling without altering the fuse base, aiding safe maintenance and quick fault identification in control panels and protection circuits. This model embodies SIBA’s emphasis on durable, semiconductor-protection solutions that combine high-current capability, voltage rating, and a compact DIN-110 footprint for practical installation in demanding equipment.
