Fuses are designed to protect electric circuits from damage caused by excessive current. The Cooper Bussmann 3SBP 1.6-R is a fast-acting, non-cycling, non-renewable, low-voltage, dual-element fuse. It is a 3-amp-rated bolt-on type fuse that is UL and CSA rated.

The 3SBP 1.6-R offers protection for a variety of applications. The most common applications include lighting, smoke detectors, air conditioning units, electronic components, transformers, and other low-voltage protection. These fuses can also provide protection in lower voltage circuits such as in audio systems and LCD displays.

It is important to note that the 3SBP 1.6-R should not be used in circuits with a rated current higher than 3 amps. Likewise, it should not be used in circuits that are subject to transient events such as short-circuits or power spikes. Finally, these fuses are designed to work only in clean environments with no contamination.

The working principle of the 3SBP 1.6-R is fairly simple. It relies on a principle known as thermal-magnetic operation, which essentially means that if the current passes through the fuse exceeds the rating, the temperature of the fuse will increase. This increasing temperature will create an oscillating magnetic field around the fuse, causing it to trip and open the circuit.

Therefore, if a circuit exceeds its rated current and the temperature of the fuse rises, the 3SBP 1.6-R will open the circuit to prevent further damage. The temperature at which the fuse trips is known as the trip temperature, and the current at which the fuse trips is the trip current.

The 3SBP 1.6-R also features a dual-element design for added protection. This design means that the 3SBP 1.6-R has two elements in parallel, one of which acts as a primary fuse while the other is a backup. This ensures that both elements need to reach their trip temperature before the fuse will trip, providing added protection for circuits.

In summary, the Cooper Bussmann 3SBP 1.6-R is a fast-acting, non-cycling, non-renewable, low-voltage, dual-element fuse. It is designed to protect a variety of applications from overload, and it relies on a thermal-magnetic operation to trip when the current exceeds its rating. Its dual-element design ensures added protection for circuits.
