Littelfuse 4A Time Delay Glass Cartridge Fuse 5 x 20 mm 250V AC 0219004.MXABP

Littelfuse 0219004.MXABP is a 4A time delay glass cartridge fuse with dimensions 5 x 20 mm, designed for protection in 250V AC circuits. Its glass body construction allows clear visual indication of fuse status, facilitating easy inspection and maintenance. This fuse is engineered to safely interrupt overcurrent conditions and short circuits by blowing, thereby protecting sensitive devices and internal circuit components.

The fuse features a T speed rating (slow blow or anti-surge), which makes it tolerant to transient current surges without unnecessary blowing. It has a low breaking capacity (LBC), ensuring adequate safety for circuits with limited fault currents. The operating temperature range is from -55°C to 125°C, enabling reliable operation under varied environmental conditions.

Common applications include electrical appliance protection in motors, air conditioners, refrigerators, pumps, and similar equipment. The 5 x 20 mm standard size fits most compatible fuse holders, making replacement and installation straightforward. This fuse complies with multiple international standards including CSA, PSE, VDE, UL, SEMKO, CE, and CCC, ensuring safety and quality recognition across many markets.

Its typical use cases span industrial, commercial, home/residential, and automotive electrical protection domains. The glass cartridge fuse design also provides a cost-effective method of safeguarding electrical circuits.

The glass body design enables inspection of fuse element condition. Rated current of 4 amps at 250V AC ensures effective protection. T speed rating denotes slow-acting fuse suitable for surge currents. Low breaking capacity (LBC) meets requirements for limited fault current circuits.

Operating temperature range from -55°C to 125°C for diverse environments. 5 x 20 mm standard size fits common fuse holders. Certified to multiple international safety standards. Ideal for industrial, commercial, residential, and automotive uses.
