Blok osigurača ST CLB - 6 položaja s negativnom sabirnicom

This is a compact 6-position circuit breaker block with an integrated negative busbar, designed for protecting electrical circuits in marine installations. It allows organizing and protecting multiple circuits from a single power source.

The ST CLB 5052-BSS circuit breaker block is designed to protect up to 6 individual circuits.

No, the push-button circuit breakers are sold separately. The block is designed to accommodate them via quick-connect clips.

This block is compatible with push-button reset-only circuit breakers, featuring quick-connect terminals.

The maximum operating voltage for this block is 32V DC (direct current).

Each individual circuit can handle a maximum current rating of 32 amperes (32A).

For the entire block, in common source configuration, the maximum operating current is 100 amperes (100A).

Yes, it is specifically designed for marine electrical installations. It includes tinned copper busbars and screw terminals for enhanced corrosion resistance in saltwater environments.

Mounting is done using #8 (M4) screws or #8 nuts. The dimensional drawing shows the mounting centers.

The block dimensions are approximately 142.9 mm (5.63") between mounting center points in length and 70.8 mm (2.79") in width. The total width is approximately 75.9 mm (2.99") and the total length is approximately 169.9 mm (6.69").

A "common source" block (such as the 5052-BSS) means that all positive circuits share the same incoming positive power supply and use an integrated negative busbar for the return. It is ideal for systems where multiple loads share the same positive power supply and a centralized negative return.

An "independent source" block (such as models 5050 or 5051) means that each positive circuit is individually powered and does not have an integrated negative busbar, requiring separate negative connections for each circuit or the use of jumpers to link the positive sources.

Yes, the 5052-BSS model is a 6-position block with an integrated negative busbar.

Yes, a transparent insulating cover is included. It is designed to meet ABYC/USCG insulation requirements.

The transparent insulating cover has square label slots to easily identify each circuit. Labels are usually not included with the block itself, but the slots are provided.

The busbars and screw terminals are made of tinned copper, ensuring reliable electrical conductivity and excellent corrosion resistance.

The unit can operate within a temperature range from -10°C to 60°C.

Yes, the block is designed for a maximum voltage of 32V DC, making it fully compatible with 12V and 24V DC marine electrical systems.

Screw terminals are #8-32 type and feature captive locking washers for secure connections.

Quick-connect clips are designed to allow push-button circuit breakers to be easily inserted and securely held in place within the block, simplifying installation and replacement.
