Modular isolating switch 2P 40A 400VAC SBN240

Modular isolating switch – reliable circuit disconnection

This 2-pole isolating switch with a rated current of 40A and a voltage of 400VAC is a key element of any electrical installation. The SBN240 from Hager guarantees safe and efficient circuit disconnection, both in domestic and industrial installations. The compact design (2 modules wide) allows for efficient use of space in the distribution board.

Functionality and safety in one

The SBN240 switch is designed for ease of installation and use. The rated switching capacity of 0.846 kA provides effective protection against short-circuit effects, and the short-circuit withstand (Icw) of 0.6 kA further increases its reliability. Thanks to the IP20 protection class, it is resistant to touch and dust, which increases the safety of use.

• Wide application: ideal for disconnecting receivers in AC circuits with a voltage of up to 400V.
• Compact dimensions: occupies only 2 modules wide, making it easy to install in tight distribution boards.
• High reliability: rated current of 40A and breaking capacity ensure effective protection of the installation.
• Safety of use: protection class IP20 protects against accidental contact with live wires and dust.
• Durability: installation depth of 68 mm ensures stable installation and long-term operation.
• Versatility: Can be used in various types of electrical installations – both new and modernized.

Construction and installation

The SBN240 is characterized by a solid construction and high quality of workmanship, typical of Hager products. Installation is on a standard TH35 rail, ensuring quick and easy installation. The cross-section of flexible conductors is 2.5 - 16 mm², and of rigid conductors 2.5 - 25 mm², allowing connection of conductors of different thicknesses. This allows installers to easily adapt the switch to the specific needs of a given project. Additionally, the color coding of the lever makes it easier to identify the device in the distribution board, and the Biconnect terminals provide convenient connection of comb busbars from 40 A to 125 A.
