A3T tipo T lydusis saugiklis – 150 A

A Class T fuse is a fast-acting electrical protection device designed for high-energy marine systems. It is used to protect circuits and equipment from damage caused by overcurrents or short circuits by quickly cutting off the electrical supply.

This fuse has a high interrupting rating of 20,000 amperes (20 kA) at 125 V DC. This feature is critical for the safety of modern installations, particularly when dealing with high short-circuit currents.

The BLUE SEA A3T Class T 150 A fuse is designed as "fast acting". This means it provides very rapid circuit interruption in case of overcurrent, minimizing potential damage to connected equipment.

It is particularly suited for protecting equipment requiring a fast response to high fault currents, such as:

High-power invertersBow thrustersWindlassesLarge-capacity battery banks, including lithium-ion batteries.

The nominal amperage of this fuse is 150 A (150 amperes).

This fuse is designed to operate in systems up to 125 V DC.

The Class T fuse offers a significantly higher interrupting rating compared to ANL or MEGA fuses of the same amp rating, while occupying a more compact form factor. It is the preferred choice for critical systems where safety and responsiveness are paramount, as well as for confined spaces.

No, a fuse is a single-use safety device. Once it has blown to protect a circuit, it must be replaced with a new fuse of the same type and rating.

Yes, this BLUE SEA A3T Class T fuse is designed for high-energy marine electrical systems, providing essential overcurrent protection in this demanding environment.

Yes, this fuse is specifically designed for protecting high-capacity battery banks, including lithium-ion batteries, due to its ability to handle very high short-circuit currents.

Installing this fuse requires a fuse holder specifically compatible with Class T. This ensures a secure connection compliant with marine electrical standards.

No, this fuse is rated for direct current (DC) use only, with a maximum voltage of 125 V DC. It is not designed for alternating current (AC) applications.

Yes, this fuse is compatible with marine electrical systems operating at 12 V, 24 V, 48 V, and any other DC voltage not exceeding 125 V DC.

Yes, when correctly rated and installed upstream of a circuit or group of devices, this fuse protects all equipment connected to that circuit from overcurrent.

Installing this type of fuse in a high-energy marine electrical system must be performed by a person with marine electrical expertise. It is critical to ensure a correct and secure installation to guarantee the effectiveness of the protection.

No, a fuse of this type generally has no polarity or specific orientation. It can be inserted into the fuse holder in any direction.

Before any work on the electrical circuit, it is essential to:

Turn off the system's main power supply.Use insulated tools to avoid electric shock or short-circuiting.Make sure the fuse holder is compatible and that the connections are clean and secure.

Yes, using a fuse holder specifically designed for Class T fuses is absolutely necessary. An incompatible fuse holder could compromise safety and proper system operation.

Fuses are sacrificial safety components. They are designed to blow and destroy themselves in case of overcurrent to protect the rest of the system. The warranty typically covers manufacturing defects, ensuring the product is functional upon receipt.

If the fuse blows, this indicates an overcurrent or short circuit in the circuit. You must first identify and resolve the cause of the issue before replacing the fuse. The replacement must be done with a new fuse of the same type and rating (150 A).
