LPS-RK-225SP - 225Amp Fuse

LPS-RK-225SP - 225Amp Fuse

When you're replacing or specifying a 225A fuse, matching amperage alone isn't enough. The Eaton Bussmann series LPS-RK-225SP is a 225A Class RK1 time-delay, current-limiting fuse rated for 600VAC and 300VDC. Eaton specifies interrupting ratings of 300 kAIC at 600VAC and 100 kAIC at 300VDC, along with dual-element construction and a blade-end × blade-end connection. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPS-RK-225SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 225A Class RK1 configuration: Provides clear amperage and fuse-class identification for matching compatible electrical equipment.
• Time-delay fuse: Eaton specifies time-delay operation, an important characteristic when the equipment requires this particular fuse behavior.
• Current-limiting construction: The manufacturer identifies this as a current-limiting fuse, another critical specification to confirm during selection.
• Dual-element design: The LPS-RK-225SP uses dual-element construction as specified by Eaton.
• 600VAC / 300VDC ratings: Rated for applications requiring the manufacturer's stated AC or DC voltage.
• Blade end × blade end connection: Makes connection style another straightforward checkpoint when confirming form and fit.
• Non-indicating configuration: Eaton identifies the LPS-RK-225SP as non-indicating.

Where It Works Best

The Eaton Bussmann LPS-RK-225SP 225A Class RK1 fuse is intended for compatible electrical equipment requiring a 225A amperage rating, 600VAC / 300VDC voltage ratings, Class RK1 construction, time-delay operation, current-limiting characteristics, dual elements, and blade-end × blade-end connections. The electrically isolated end cap is another manufacturer-listed feature to check when confirming the required fuse configuration.
