Industrial WUY Heat Limiter Specialty Fuse 30A 600V

The Bussmann by Eaton WUY Heat Limiter Specialty Fuse is a 30 A, 600 V low‑voltage fuse with a fork‑connector style designed for use in W Series fuse blocks. As a heat limiter, it interrupts current when the opening temperature reaches 236°C (approximately 460°F), with a hold temperature around 224°C to prevent nuisance trips. The device employs 23 mm fixing centers to fit standard W‑Series mounting provisions and is cataloged under the WUY family of heat limiters. This specialty fuse protects electrical cables and conductors from overheating in control panels and other low‑voltage circuits by providing a thermal trip to prevent insulation damage or fire risk. When selecting protection, verify the current rating and compatible W‑Series fork terminals in your enclosure to ensure proper fit and electrical performance.
