Littelfuse SOO Series Dual-Element Type S Slo-Blo Plug Fuse, 125V

Littelfuse SOO Series Dual-Element Type S Slo-Blo Plug Fuse, 125V

The Littelfuse SOO Series is a line of dual-element, time-delay Type S plug fuses engineered primarily for motor and motor branch-circuit protection, while remaining fully suitable for all general purpose circuits. Every fuse in the SOO Series is rated 125VAC and is available in ampere ratings from 0.5A to 14A, so electricians can match precise overcurrent protection to the exact circuit requirement. The Slo-Blo (Time Lag/Time Delay) opening characteristic lets these fuses ride through momentary inrush current and motor starting surges without nuisance blowing, while still opening reliably under sustained overload conditions to protect wiring and connected equipment. The Type S base is a standard plug fuse package size designed for panels equipped with Type S fuse holders, helping prevent installation of an incorrectly rated fuse.

Key Features

• Ampere Rating Range: the SOO Series is available from 0.5A to 14A, allowing precise overcurrent protection sized to the connected motor or branch circuit.
• Voltage Rating: 125VAC rating suits standard residential and commercial plug fuse panels.
• Time-Delay (Slo-Blo) Opening: Time Lag/Time Delay (T) opening characteristic allows momentary motor starting inrush current to pass while still protecting against sustained overloads.
• Dual-Element Construction: combines a fast-acting overload element with a thermal time-delay element for dependable motor and motor branch-circuit protection.
• Type S Plug Fuse Base: the standard Type S base package size is designed for Type S fuse holders and helps prevent installation of an incorrectly rated fuse.
• General Purpose Versatility: also suitable for all general purpose circuits beyond motor branch-circuit protection, making the SOO Series a practical replacement fuse for a range of plug-fuse panels.
• Package Size: supplied as a compact plug fuse for direct installation into compatible Type S fuse holders.
