Terminal Blocks - Barrier Blocks

Barrier terminal blocks group several individual terminal blocks together that are connected to one another electrically by small metalized barriers. These components are intended for the distribution, connection, disconnection, monitoring, and protection of electrical signals in electrical installations. Barrier terminal blocks are commonly used in control cabinets and for decentralized terminal blocks.

1-1546977-2 Application Field and Working Principle

1-1546977-2 barrier terminal blocks are developed for power supply networks and distribution systems. They provide the possibility of direct terminal connections in common rail systems with high nominal currents, and allow for an easy connection of several devices and elements. The 1-1546977-2 barriers also feature a safety interlock that provides double insulation and protects against dangerous circuit states. The safety interlock also allows for larger distances between the terminals, which reduces the risk of short circuits.

The 1-1546977-2 terminal blocks have an insulated O-ring that provides an improved contact design, which helps reduce the possibility of shorts. It also offers stable force connection, and ensures that the terminal block is retained firmly at the desired current.

The 1-1546977-2 have a single-pole connection with a clamping force of 6.3 N. The housing consists of polyamide material, with a flexible carrier strip that together create a reliable connection. Furthermore, the terminals feature nickel-plated contacts for excellent electrical conductivity. These components are designed for a rated voltage of up to 630 V (AC/DC) and a rated current of up to 16 A.

The 1-1546977-2 terminal blocks are available in a range of sizes and configurations, and have snap-on components for easy installation and removal. The terminal blocks are suitable for use in indoor and outdoor environments due to their IP65 protection rating, and have a temperature range of -25 to +85℃. They are also UL and CSA approved, and RoHS compliant.

In conclusion, the 1-1546977-2 terminal blocks are designed to meet the requirements of power supply networks and distribution systems, and are capable of providing reliable and safe connections. They are easy to install, and are suitable for a wide range of applications.
