Fuses are essential components for protecting electrical circuits from overload. The 3AP 1.6 is a high speed, low voltage, medium interrupting current, three-pole air-break fuse. It is designed to provide fast and reliable protection in a variety of applications. It is available in various sizes and configurations and is UL listed for branch circuit protection.

Application Field

The 3AP 1.6 is suitable for installations in dry locations such as residential, commercial, and industrial buildings. It is also designed to be used with residential, commercial, industrial, and lighting systems. It is suitable for single phase and three phase installations and provides protection against line and load side short circuits, as well as overcurrents. It is typically used in applications such as:

• Motor circuit protection
• Generator circuit protection
• Hydraulic circuit protection
• AC/DC converter protection
• Power factor control protection

Working Principle

When a circuit becomes overloaded or short circuited, the contacts in the 3AP 1.6 fuse will melt, disconnecting the circuit and preventing further damage. The time it takes for the fuse to operate is called the clearing time. The clearing time of the 3AP 1.6 is very fast, so it provides fast and reliable protection from overcurrents or short circuits. The current rating of the fuse must always be lower than the maximum current rating of the circuit to be protected.

The 3AP 1.6 has a primary temperature-sensitive element, which melts when the temperature reaches a predetermined level, and a secondary element. The melting of the primary element disconnects the circuit and the secondary element acts as a back up, further disconnecting the circuit in order to provide additional protection. The 3AP 1.6 is designed to safely interrupt the circuit and minimize arcing and fire hazards.

In summary, the 3AP 1.6 is a fast, reliable, and UL listed fuse that can be used for a variety of installations. It is designed to provide fast protection against overloads and short circuits, and minimize arcing and fire hazards. The current rating of the fuse must always be lower than the maximum current rating of the circuit to be protected to ensure safe operation.
