Overview
The Bussmann LKS-30 is a fuse link with a current rating of 30 Amps and a voltage rating of 600VAC. The LKS-30 is suitable for use with Class H and Class K5 fuse. This renewable fuse link is designed for non-current-limiting applications where the available fault current is less than 10000 amps and frequent outages dictate the economy of these renewable type fuses. The LKS-30 is part of the Bussmann super lag series, offering extended time-lag protection for industrial and commercial electrical systems.
Key Features
- Super Lag Characteristics: Longer time-lag than other Class H fuses of this type can better sustain overloads without needlessly opening
- Renewable Design: Can be reused after operation, reducing replacement costs
- Class H and K5 Compatible: Meets industry standards for safe operation
- Non-Indicating: Standard design without signal indicator
- Bulk Package: Box of 18 units for maintenance stock and spares
