Fuse model: T4AL250V. Fuse current: 4 A. Fuse voltage: 250 V. Fuse dimensions: 5 x 20 mm / 0.2 x 0.78 inches. The role of slow impact glass fuses: the slow fuse. is also referred to as delay fuses. Its delay characteristic is retained in the circuit if you have a error-free pulse current, and can be used before a long-term Protect overload. Some circuits have a current, which several times above the normal operating current to switching time. Although this current peak is very high, occurs for a short period of time. We call it pulse current, Inrush current or surge current. Ordinary Fuses cannot resist such currents. If such circuit uses an ordinary fuse, it can May not tarnish normally. If a larger fuse is used, if the Circuit not protected. The melting of the time-delayed Fuse is specially processed to absorb energy. By adjusting the energy consumption, the inrush current and the overload. ## Features - BOJACK Pack of 20 high-quality slow impact glass fuses - Fuse size: 5 x 20 mm / 0.2 x 0.78 inches - Fuse current: 4A - Fuse voltage: 250 V - Quantity per package: 20 pieces.
