Bussmann JKS-150 Limitron Current Limiting Fuse

Bussmann Limitron JKS-150 is a fast-acting, current-limiting fuse rated for 150 A at 600 VAC, designed to protect 600-volt circuits with minimal let-through energy. It is part of the Limitron JKS family (Class J) and uses a single-element cartridge body, delivering an interrupt rating of up to 200 kA at 600 VAC. This 150 A device provides rapid fault isolation to limit damage to downstream equipment such as transformers, motor controllers, and power supplies in industrial and commercial electrical systems. The JKS-150 is widely cataloged as a Limitron fuse with the JKS designation and is recognized for its combination of fast response and high interrupt capability within 600 VAC circuits. In practical terms, it offers reliable short-circuit protection by quickly interrupting fault currents, helping safeguard wiring, components, and control circuits in 600 VAC applications.
