Drive connector coupling extension, DMV250N/400N(135mm) 4K10K3H135 1050240

Extension of the drive connector shaft, DMV250N/400N(135mm) is a dedicated element used to increase the range of motion of the drive mechanism in EATON DMV series circuit breakers. It is a key component during the installation and modernization of electrical switchboards, especially where precise adaptation to the existing infrastructure is required.

Compatibility and application

The extension is designed to work with DMV 250N and 400N drive connectors. Its main task is to enable the correct operation of the disconnecting mechanism in situations where the standard shaft length is insufficient. This allows installers to flexibly adapt the device to specific mounting conditions, avoiding problems with access or collisions with other elements of the switchboard.

• Application in low-voltage switchboards: Ideal for control cabinets and electrical switchboards in commercial, industrial and residential buildings.
• Modernization of existing installations: Enables easy adaptation of older circuit breakers to new requirements without the need to replace the entire device.
• Precise fit: Ensures accurate positioning of the drive mechanism, which translates into reliable operation of the circuit breaker.

Construction features and parameters

Made of high-quality materials, the shaft extension is characterized by its solidity and durability. Its cross-section width is 10 mm, the cross-section height is also 10 mm, and the length is 135 mm - these dimensions ensure adequate mechanical strength and stability during operation. Precise workmanship guarantees trouble-free installation and smooth operation of the drive mechanism.

Thanks to this, the shaft extension is a reliable solution for professionals looking for high-quality components for electrical power systems. It is an essential accessory for the installation and servicing of EATON DMV circuit breakers, ensuring the safety and efficiency of the entire electrical installation.
