UL Class T – Fast

OptiFuse’s new UL listed Class T fuses provide fast acting protection combined with high current limiting capabilities for main feeder branch circuit protection (UL 248-15). They are the most compact option available for ratings exceeding 30A.
Class T fuses are designed to protect devices such as load centers, panelboards, switchboards, measuring centers, and other surge-sensitive equipment from both overload and short circuit currents. They can be found in systems such as pumps, HVAC, and power sources.
Rated at 600VAC / 300VDC, these fuses have a 200K amp AC interrupting capacity and a 50K amp DC interrupting capacity. Current ratings range from 1A to 400A.
