Jističový blok ST CLB - 6 pozic s integrovanou negativní sběrnicí

This is a 6-position compact 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 common power source.

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

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

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

The maximum operating voltage for this unit is 32V DC.

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

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

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

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

The block dimensions are approximately 142.9 mm (5.63") between mounting center holes lengthwise 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 all positive circuits share the same incoming positive supply and use an integrated negative busbar for return. It is ideal for systems where multiple loads share the same positive supply and a centralized negative return.

An "independent source" block (such as the 5050 or 5051 models) means each positive circuit is individually powered and does not include 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-format label slots to easily identify each circuit. Labels are usually not included with the block itself, but the slots are provided.

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

The screws are #8-32 type and feature captive locking washers for secure connection.

The 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.
