LPS-RK-500SP - 500Amp Fuse

LPS-RK-500SP - 500Amp Fuse

When you're matching a 500A fuse, amperage is only the starting point. The fuse class, voltage, interrupting rating, connection style, operating characteristics, and physical size must match the application. The Eaton Bussmann series LPS-RK-500SP is a 500A Class RK1 time-delay, current-limiting fuse rated for 600VAC and 300VDC. For electricians, maintenance departments, and electrical equipment owners, these specifications provide practical identification points before installation. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPS-RK-500SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 500A Class RK1 configuration: Combines a 500-amp rating with a Class RK1 design, giving you two critical specifications to confirm when matching a fuse to existing equipment.
• Time-delay operation: Eaton classifies the LPS-RK-500SP as a time-delay fuse. Match this characteristic to the protection requirements of the circuit and connected equipment.
• Current-limiting design: The manufacturer identifies this fuse as current-limiting, an important operating characteristic to verify when selecting circuit protection.
• Dual-element construction: Eaton specifies a dual-element internal configuration.
• 600VAC / 300VDC voltage ratings: Suitable only where the fuse's specified AC or DC voltage rating and all other application requirements are appropriate.
• Blade end × blade end connection: The blade-style connection provides another important checkpoint when confirming physical compatibility.
• Non-indicating configuration: Eaton identifies this catalog number as non-indicating.
