Bussmann SC-1/2 Time Delay Fuse

Reliable Circuit Protection

The Bussmann SC-1/2 Time Delay Fuse safeguards electrical systems against sustained overcurrents and short circuits. Engineered for durability and precision, this fuse features a “slow-blow” design that withstands harmless temporary inrush currents (common in motors, transformers, and solenoids) while reliably interrupting dangerous fault conditions.

Key Features

• Time-Delay Functionality: Tolerates brief startup surges (5-10x rated current) without nuisance tripping, ideal for inductive loads.
• Precise Interrupting Capacity: Clears high-current faults rapidly to prevent equipment damage.
• 0.5A Current Rating: Rated for 1/2 amp (500mA) operation at 250V AC/DC.
• Industrial-Grade Construction: Ceramic body with sand-filled quartz for arc suppression and stable performance.
• Compact SC Size: Space-efficient 5×20mm cartridge design, compliant with IEC 60127-4 standards.

Applications

• Motor control circuits
• HVAC systems
• Transformers and solenoids
• Power supplies and industrial automation
• Lighting ballasts
