Bussmann S505-800-R Time Delay Fuse

Bussmann S505-800-R Time Delay Fuse

Industrial-Grade Protection for Demanding Circuits

The Bussmann S505-800-R is a high-performance time-delay fuse engineered by Eaton’s Bussmann series to safeguard electrical systems against overloads and short circuits. Designed for reliability in industrial and commercial applications, its dual-element construction ensures optimal coordination with motors, transformers, and other inductive loads.

Key Features:

• 800A Amp Rating: Handles high-current circuits with precision.
• 600V AC Voltage Rating: Suitable for robust industrial power systems.
• Time-Delay Design: Withstands temporary inrush currents (e.g., motor startups) while interrupting sustained overloads and faults.
• Dual-Element Technology: Separately manages overloads (slow response) and short circuits (instantaneous trip) for enhanced safety.
• High Interrupt Capacity: 200kA IR rating ensures reliable protection under extreme fault conditions.
• Rejection Base (R-Type): Prevents accidental installation of incorrect fuses, complying with NEC safety standards.
• Compact Cylindrical Body: Space-efficient and compatible with standard fuse holders.

Ideal For:

• Motor control centers (MCCs)
• HVAC systems
• Industrial machinery
• Power distribution panels
• Transformer protection
