Blok bezpiecznikowy klasy T z izolowaną pokrywą – 225 do 400 A

The Blue Sea Systems T-Class fuse block 5502100-BSS is designed for fast protection of high-current electrical circuits. It is specifically intended for inverters and large battery banks in marine applications.

This fuse block can support a maximum voltage of 160V DC.

The 5502100-BSS fuse block can handle a maximum amperage of 320A in operation. If the block is installed inside an engine compartment and for continuous use, the recommended maximum amperage is 300A.

This block is compatible with Class T fuses rated between 225A and 400A. Note that fuses are sold separately.

No, Class T fuses compatible with this block are sold separately and are not included with the product.

The fuse block dimensions are as follows:

Length: 177.8 mm (7.00 in)Width: 50.8 mm (2.00 in)Height: 58.4 mm (2.3 in)

Yes, this fuse block is certified compliant with the flame-resistant requirements of ISO 8846 and SAE J1171. It also complies with Directive 2013/53/EU for recreational craft.

The fuse mounting bus of this block is made of tinned copper, which ensures excellent conductivity and corrosion resistance.

The insulating cover meets ABYC/USCG insulation requirements. It also features convenient breakout points for cable access in all directions, making installation and wiring easier.

The fuse block base is made from UL 94-V0 material. This material provides excellent resistance to high temperatures, contributing to the product's safety and durability in demanding environments.

The 5502100-BSS model is designed for higher amperage, accepting Class T fuses from 225A to 400A, with 5/16"-18 studs and a maximum torque of 107 in-lb [12.9 N-m]. In contrast, the 5007100 model covers amperages from 110A to 200A, uses 1/4"-20 studs, and a torque of 72 in-lb.

The fuse block is mounted using holes sized for 1/4" or M6 fasteners. The mounting hole spacing is 158.8 mm (6.25 in).

The maximum recommended torque for stainless steel serrated flange nuts is 107 in-lb [12.9 N·m]. Use a 1/2" socket for tightening.

For continuous use (more than 15 minutes) inside an engine space with a 400A fuse and 105°C wire, it is recommended to use 2 cables of 4/0 AWG (2 x 120mm²).

The four 5/16"-18 stainless steel studs on this fuse block are designed to accept M8 eyelet terminals.

Yes, this fuse block is fully suitable for 12V and 24V systems, as it is designed to handle a maximum voltage of 160V DC, which comfortably covers these common applications.
