Eaton S-3-2/10 Fustat Time-delay Fuse 3-2/10A

Product Description

The EATON S-3-2/10 is a Fustat dual-element time-delay fuse rated at 3-2/10 amps, designed for Edison base (Type S) fuse holders. Dual-element construction separates the overload and short-circuit response elements, allowing the fuse to tolerate brief inrush currents from motors and transformers while still providing fast response to dangerous fault conditions. This design reduces nuisance blowing during normal equipment startup. Installation is typically performed by licensed electricians as part of branch-circuit or equipment protection in residential and light commercial panels, appliance connections, and motor circuits.

The S-3-2/10 is suited for use in residential service panels, sub-panels, and fused disconnect switches where Edison base fuse protection is required. Its time-delay characteristic makes it a practical choice for protecting single-phase motor loads, HVAC equipment, and appliances subject to startup inrush. The Type S base is rejection-style, meaning the fuse holder physically prevents installation of a higher-amperage fuse, which is a built-in overcurrent protection safeguard.

Key Features

• Dual-element time-delay design tolerates motor inrush while clearing sustained overloads and short circuits
• Type S (Fustat) rejection base prevents overfusing by blocking higher-rated fuses from seating
• 3-2/10 amp rating suited for small motor and appliance branch-circuit protection
• Designed for use in standard Edison base Type S fuse holders and fused disconnects

Compatibility

Designed as an OEM-style replacement for Type S Edison base fuse holders requiring a dual-element time-delay fuse at 3-2/10 amps. Specific model compatibility was not provided; verify fuse holder type and ampere rating before installation.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC Article 240 requirements for overcurrent protection. Always de-energize the circuit and verify zero voltage at the fuse holder with a meter before servicing. Confirm the fuse holder is a Type S rejection base before inserting the fuse. Do not substitute a fuse of a higher ampere rating than the circuit requires.
