RS PRO 1A T Speed Glass Cartridge Fuse, 5 x 20 mm, 250V AC, Time Lag, Glass Body 178-4155

RS PRO 178-4155 is a glass cartridge fuse engineered for protection of electrical circuits with a 1 ampere current rating and 250V AC voltage specification. This T Speed (time lag) fuse is characterized by its slow acting or anti-surge feature, allowing it to tolerate short pulses of high current without blowing, ideal for motor start-ups and other inductive loads.

The fuse measures 5 x 20 mm with a glass body that enables visual inspection of the fuse element, which simplifies monitoring and replacement. The product operates reliably within a temperature range from -55°C to 125°C and is designed as Low Breaking Capacity (LBC), offering safe interruption of overcurrents without damage to equipment.

Typical applications include protection of motors, air conditioners, refrigerators, pumps, and other electrical appliances in industrial, commercial, automotive, and residential environments. The RS PRO series fuse complies with multiple approvals including RoHS, UL, CSA, KTL, and PSE GTE, ensuring high-quality standards and electrical safety.

Cartridge fuses like this model are cost-effective solutions for safeguarding circuits from short circuits and overhead currents. Once a fuse has blown, it must be replaced to restore circuit function, ensuring continual protection.

Features a 5 x 20 mm standard cartridge fuse size for board and panel protection. Has a Time Lag characteristic suitable for anti-surge and slow blow applications. Rated current of 1 ampere and voltage of 250V AC for reliable operation.

Constructed from glass enabling visual inspection for fuse continuity. Designed to withstand operating temperatures from -55°C up to 125°C. Low Breaking Capacity to protect devices from short circuits and overcurrent. Suitable for industrial, commercial, automotive, and residential electrical protection.

Conforms to RoHS, UL, CSA, KTL, and PSE GTE standards for safety and compliance. For detailed selection and integration, consult RS PRO catalog and technical documents to ensure compatibility with your electrical system and fuse holders.
