Insulated busbar IZ10/L1NL2NL3N/12E 002921212

Insulated busbar for three-phase switchboards

The IZ10/L1NL2NL3N/12E insulated busbar is a professional component used for connecting modular devices in three-phase switchboards. The product provides a safe and reliable connection of three phases (L1, L2, L3) and the neutral conductor (N) in a single, compact design.

Operating parameters and safety

The busbar operates at a rated current of 63A and a maximum operating voltage of 690V, making it suitable for most residential and commercial installations. The design features a 10 mm² conductor cross-section, which ensures optimal conductivity while maintaining compact dimensions.

A clearance distance of 17.8 mm guarantees safe separation between individual conductors, eliminating the risk of phase-to-phase short circuits. The busbar is suitable for operation in both AC systems with a rated voltage of 500V and DC systems at the same voltage level.

Construction and connection type

The product utilizes a fork connection (FORK), which enables fast and secure mounting of modular devices. This type of connection provides a large contact surface and mechanical stability, resulting in low contact resistance and minimal energy loss.

The construction includes a length corresponding to 12 modules, allowing for the installation of a standard number of devices in a typical residential or office switchboard. The busbar is equipped with insulation, which protects against accidental contact with live parts and provides additional protection against environmental conditions.

Application in electrical installations

The insulated busbar is used in three-phase installations with a neutral conductor, where uniform distribution of electrical energy to multiple circuits is required. It is particularly useful in main switchboards for residential buildings, offices, and commercial facilities.

The product enables the creation of organized electrical installations by centrally distributing power to individual circuit groups. Thanks to the design including a neutral conductor, the busbar is ideal for installations with single-phase loads requiring a neutral wire.

The standard length of 12 modules allows for flexible installation expansion planning and easy adaptation to various configurations of modular devices mounted in the switchboard.
