Bussmann LPN-RK-1SP Low-Peak Fuse 1 A Dual Class RK1 Time Delay 250 Vac 125 Vdc

Description

Features

• Featuring a true dual-element design, the LPN-RK-1SP provides a minimum 10-second time-delay at 500% of its rated current. This allows commercial contractors and industrial maintenance teams to size fuses closer to the motor s actual full-load current, preventing annoying "nuisance blows" during heavy equipment startups while still delivering precise, tight protection against sustained overloads.
• Boasting an exceptional 300,000-amp interrupting rating (AIR) at 250V AC, this Low-PeakTM fuse safely clears catastrophic electrical faults under maximum current conditions. Its advanced current-limiting design stops damaging short-circuit energy before it can peak, safeguarding downstream components like contactors and circuit breakers from catastrophic thermal and magnetic destruction.
• Engineered with standard Class RK1 physical dimensions and rejection slots, this fuse is mechanically built to fit securely into code-compliant RK1 fuse blocks and disconnects. This fail-safe geometry prevents field technicians from accidentally replacing it with an inferior, lower-rated Class H or K fuse, keeping your electrical infrastructure strictly code-compliant and safely optimized.
• Constructed with high-grade copper alloy end-caps and a heavy-duty fiberglass tube body, this fuse provides excellent heat dissipation and structural integrity. The low-resistance contact design minimizes localized power loss and voltage drops, ensuring cool-running operation inside cramped safety switches and industrial control panels exposed to humidity and temperature fluctuations.
