Three-phase bridge blocks B3.0/3-PKZ0 232289

Three-phase busbar blocks – a reliable connection in the installation

Three-phase busbar blocks B3.0/3-PKZ0 are components designed for building safe and efficient electrical circuits. They find application in both industrial installations and commercial buildings where high reliability and connection stability are required. The design of these blocks allows for easy assembly and disassembly, and their solid construction guarantees long-term operation.

Characteristics and application

B3.0/3-PKZ0 blocks are used to connect phases in three-phase installations, providing a stable current flow to connected devices. A width of 7.5 modules allows for efficient use of space in the switchgear cabinet. Made of black plastic, they are characterized by high resistance to mechanical damage and external factors. The use of fork-type electrical connectors facilitates quick and secure cable installation. These blocks are particularly useful when connecting motor starters, contactors and other devices requiring three-phase power. A rated continuous current of 63A allows for servicing devices with significant power.

Advantages and benefits

• High short-circuit breaking capacity: Provides effective protection of the installation against the effects of overloads and short circuits – even with high surge currents (up to 6kV).
• Phase failure detection: The built-in phase failure detection function increases the safety of the installation, minimizing the risk of damage to connected devices.
• Compatibility with the PKZM0 series: Common accessories with the PKZM0/PKZM01/PKZM4 series (release coils, auxiliary contacts) allow for flexible adaptation to specific application needs and reduce storage costs.
• Easy installation: Tool-free connection with DILM7..15 contactors using PKZM0-XDM12 significantly speeds up the installation process and reduces labor costs.
• Safety: With insulation, protects against accidental contact with conductive elements.
• Durability: Made of high-quality materials, they guarantee long life and reliable operation even in harsh working conditions (maximum operating voltage 690V).
• Versatility: Can be used with various devices with a power of up to 7.5 kW (at 400V).

B3.0/3-PKZ0 busbar blocks are a solid solution for professionals who value quality, safety and ease of installation. They are an integral part of modern electrical installations, providing reliable power to connected devices for years to come.
