The SV 9674438 from Rittal is an end holder for the distribution busbar system in switch disconnector fields. It provides vertical support for the busbar system when power is supplied from above and ensures stable fixation of the busbar at the end of the switch field. The product is specifically designed for busbars with a width of 80 mm and a height of 10 mm, making it compatible with the standard E-Cu system. The construction made of duroplastic polyester offers high mechanical strength and resistance to chemical influences, suitable for use in industrial environments.

Applications

The end holder is used in power distribution within enclosures, particularly in switch disconnector fields, where secure and durable fixation of the busbar is required. It is intended for applications where power supply comes from above, transferring the load to the end holders. Typical use is in industrial electrical installations, such as in manufacturing, power supply, or automation technology.

Functions and Equipment in Detail

The end holder is designed for 3-pole and 4-pole arrangements, making it flexible for various switching configurations. It is supplied with mounting brackets and screws, enabling secure installation on the enclosure wall or within the switch field. The material choice of duroplastic polyester ensures high heat resistance and mechanical stability, even under load from electrical currents and mechanical stress.

Technology Explained Simply

Duroplastic polyester is a thermosetting plastic material that cannot be plastically deformed after curing. It is characterized by high strength, heat resistance, and chemical resistance, making it particularly suitable for use in electrical switchgear. The dimensions of the compatible busbar (80 mm width, 10 mm height) are standardized and correspond to the E-Cu system, widely used in many industrial distribution systems. The vertical support provided by the end holder prevents sagging or shifting of the busbar, especially in longer installations or under high loads.

Compatibility and Accessories

The end holder is specifically designed for busbars with dimensions of 80 mm width and 10 mm height. Compatible accessories available in the range include the E-Cu 80x10 mm busbar with a length of 2400 mm. This busbar can be directly connected to the end holder to create a stable distribution system. The combination of end holder and busbar enables structured and secure power distribution within the enclosure.

Mounting and Installation

Installation is carried out using the included mounting brackets and screws, which fix the end holder to the enclosure wall or within the switch field. The busbar is inserted into the end holder, thereby securing it against vertical movement. Installation is simple and requires no additional tools.

Advantages in Operation

The end holder ensures durable and secure fixation of the busbar, increasing the reliability of power distribution. The use of duroplastic polyester ensures long service life and resistance to environmental influences. Compatibility with the E-Cu system and support for 3- and 4-pole arrangements increase flexibility in planning and installing switchgear. Simple installation and stable busbar seating reduce maintenance requirements and enhance operational safety.
