Blok pojistek třídy T s izolačním krytem - 225 až 400 A

A Class T fuse block is an electrical protection device designed to hold Class T fuses. These fuses are specifically used in high-current systems, typically between 225 and 400 amperes, to protect circuits from severe overloads and short circuits. Their main feature is ultra-fast melting, essential for protecting sensitive equipment and large-diameter wiring.

This fuse block is designed to accommodate Class T fuses with an ampere rating range from 225 to 400 amps. It is important to select a Class T fuse suitable for the maximum current of your circuit.

Class T fuses provide an ultra-fast blow characteristic, which is critical for protecting sensitive electronic equipment and large-diameter wiring from massive short circuits or sudden overloads. Unlike ANL or MIDI fuses, which may have a slower response time, Class T fuses are ideal for applications where an instantaneous cutoff is required to prevent severe damage.

Yes, the insulating cover is included with the Class T fuse block BLUE SEA (reference 5502-BSS). This cover is a critical safety component, preventing accidental contact with live terminals.

This fuse block is designed to operate with electrical systems up to a maximum voltage of 160V DC (direct current).

Yes, this fuse block is specifically designed by BLUE SEA for marine applications. Its robust materials and insulating cover make it suitable for the demanding conditions encountered aboard ships and boats, ensuring reliable protection of electrical systems.

The primary function of the insulating cover is to provide protection against accidental contact with the live terminals of the fuse block. It enhances the safety of the installation by reducing the risk of electric shocks or unintentional short circuits, especially in confined spaces.

This fuse block is ideal for very high-current applications where fast protection is critical. It typically includes:

High-capacity battery banks.Power inverters.Bow thrusters.Electric windlasses.Any other equipment requiring overcurrent protection from 225 to 400 amperes.

No, the Blue Sea Systems Class T fuse block (part number 5502-BSS) is sold without fuses. Class T fuses (225 A to 400 A) must be purchased separately to match your installation's specific requirements.

The fuse block is designed for the marine environment, which implies a certain level of robustness against humidity and water spray. However, it is not classified as waterproof or submersible. It is recommended to install it in a location protected from direct immersion and heavy spray to ensure its longevity and proper operation.

Installing this fuse block involves securely connecting large-gauge cables to the terminals, then inserting the appropriate Class T fuse. It must be mounted firmly on a flat surface using the provided mounting holes. It is strongly recommended to use a qualified marine electrician to ensure correct and secure installation in compliance with current standards.

Yes, safety is paramount when installing high-power electrical components:

Disconnect all power sources (batteries, chargers) before starting the installation.Use insulated tools to prevent accidental short circuits.Ensure cables are of the appropriate gauge for the current carried.Respect positive and negative polarities.Tighten all connections properly to avoid excessive resistance and overheating.Check for absence of voltage before touching terminals.

The fuse block must be securely mounted on a stable, non-conductive surface using the two mounting holes provided. It is recommended to choose a location that is easily accessible for fuse inspection and replacement, but protected from shocks and direct water splashes. Ensure the location allows for adequate ventilation and provides sufficient space for wiring.

Yes, this fuse block is designed to be mounted in various orientations (horizontal or vertical), depending on the available space and your installation configuration. The important thing is to ensure a secure fastening and easy access for maintenance, while observing wiring safety precautions.

This block is specifically designed for use with Class T fuses. It is imperative to use only this type of fuse to ensure adequate protection of your electrical system. Class T fuses are sold separately.

Yes, this fuse block is compatible with systems operating at 12V, 24V, 48V and other DC voltages, provided the system’s maximum voltage does not exceed 160V DC. It is critical to select a Class T fuse with a rated voltage equal to or higher than your system’s voltage.

Although this fuse block is optimized and designed for the marine environment, it can technically be used in other demanding applications requiring Class T fuse protection (225-400A) and a maximum voltage of 160V DC. However, its robustness and corrosion resistance features are specifically tailored for marine conditions.
