LPS-RK-20SP - 20Amp Fuse

LPS-RK-20SP - 20Amp Fuse

Choosing the right fuse takes more than matching the 20A number on the label. Fuse class, voltage, interrupting rating, time-current characteristics, connection style, and physical size all matter. The Eaton Bussmann series LPS-RK-20SP is a 20A Class RK1 time-delay, current-limiting fuse rated for 600VAC and 300VDC. When properly selected, installed by your qualified electrical personnel, and operated within its specified ratings, the LPS-RK-20SP is built to last as part of a correctly designed and maintained electrical system.

Key Features and Benefits

• 20A Class RK1 fuse: Clearly defined amperage and fuse-class specifications help with accurate identification for compatible equipment.
• Time-delay operation: Eaton identifies the LPS-RK-20SP as a time-delay fuse, an important characteristic when matching the required circuit-protection behavior.
• Current-limiting design: The manufacturer-specified current-limiting construction is another key selection point when confirming the correct fuse.
• Dual-element construction: Eaton specifies two elements for this LPS-RK model.
• 600VAC / 300VDC voltage ratings: Supports compatible applications requiring the manufacturer's stated AC or DC rating.
• Ferrule End × ferrule end connection: A physical connection detail that should match the intended fuse holder and equipment.
• Non-indicating configuration: Eaton identifies the LPS-RK-20SP as a non-indicating fuse.
