LPS-RK-30SP - 30Amp Fuse

LPS-RK-30SP - 30Amp Fuse

Getting the right fuse means checking more than the amp rating printed on the label. Fuse class, voltage, interrupting rating, operating characteristics, connection style, and physical dimensions all matter. The Eaton Bussmann series LPS-RK-30SP is a 30A 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-30SP is built to last as part of a correctly designed and maintained electrical system.

Key Features and Benefits

• 30A Class RK1 configuration: The 30-amp rating and Class RK1 designation provide two immediate checkpoints when matching the fuse to equipment requirements.
• Time-delay operation: Eaton identifies the LPS-RK-30SP as a time-delay fuse, making its operating characteristic easy to confirm against circuit requirements.
• Current-limiting design: Current-limiting characteristics are specified by Eaton for this catalog number.
• Dual-element construction: The fuse uses the manufacturer's specified dual-element configuration.
• 600VAC and 300VDC ratings: Clearly defined AC and DC voltage ratings help simplify specification matching.
• Manufacturer-specified response time: Eaton lists a response time of 10 seconds at 500% for the LPS-RK-30SP.
• Ferrule-to-ferrule connection: This connection configuration provides an important physical checkpoint when confirming compatibility.
• Non-indicating configuration: Eaton identifies this particular fuse as non-indicating.

Where It Works Best

The Eaton Bussmann LPS-RK-30SP 30A Class RK1 fuse is intended for compatible electrical equipment requiring its particular combination of a 30A rating, 600VAC / 300VDC voltage ratings, Class RK1 configuration, time-delay operation, current-limiting characteristics, dual-element construction, and ferrule-end × ferrule-end connection. Its electrically isolated end cap is another detail to check when matching an existing fuse.
