Modular disconnecting switch 3P 80A 400V SBN380

Modular isolating switch – reliable power disconnection

This three-pole isolating switch with a rated current of 80A and a voltage of 400V is a key element of any electrical installation, providing safe and reliable disconnection of circuits. The SBN380 from Hager is a proven choice for both professional installers and end-users looking for a solid solution for residential and industrial switchboards.

Functionality and application

The SBN380 switch is primarily used as a main switch in switchboards, allowing complete isolation of the circuit from the power supply. It can also be used as an individual switch in more complex electrical installations. The lack of built-in overcurrent protection means that the device focuses exclusively on the isolation function – which is important in situations requiring a complete power cut during maintenance or service work. The ability to secure the switch against accidental switching with seals increases safety.

Characteristics and benefits

• High reliability: Rated switching capacity of 1.354 kA guarantees effective circuit interruption in the event of a short circuit.
• Compact dimensions: A width of only 3 modules makes it easy to install even in tight switchboards.
• Solid construction: Made of high-quality materials ensures long-lasting and trouble-free operation.
• Safety of use: The ability to seal in the ON/OFF position prevents accidental switching of the circuit.
• Versatility: Designed to work with AC 400V voltage, meets the requirements of most standard electrical installations.
• Easy installation: Mounting on a DIN rail allows for quick and easy installation.
• Suitable for different wire cross-sections: Supports flexible wires with a cross-section of 6-35 mm² and rigid wires with a cross-section of 6-50 mm².

Provides a rated current of 80A at a voltage of 400V, and its rated switching capacity is 1.354 kA. The device has 3 poles and occupies a width of 3 modules. The degree of protection is IP20 and the short-circuit strength (Icw) is 0.96 kA, guaranteeing safety of use. The installation depth is 68 mm.

The SBN380 switch is an investment in the safety and comfort of the electrical installation. Its solid construction, high reliability and ease of installation make it the ideal choice for both professionals and demanding end-users.
