Modular isolating switch 3P 25A 400VAC SBN325

Modular isolating switch – safety and functionality in one

This three-pole isolating switch with a rated current of 25A and a voltage of 400VAC is a reliable solution for safely disconnecting electrical circuits. Designed for both professional installers and end-users, it provides effective isolation and protection of the electrical installation. Its compact design, occupying only 2 modules, allows for optimal use of space in the distribution board.

Construction and application

The SBN325 switch is designed for use in AC circuits, offering a high short-circuit breaking capacity of 0.529 kA. Made of high-quality materials, it ensures durability and reliable operation. Thanks to the clear lever with a color-coded position marking (ON/OFF), it is easy to check the circuit status. It is an ideal solution for home, commercial and industrial installations where safe and reliable disconnection of the load is required. Designed for mounting on a TH35 rail.

Advantages and benefits

• Safety: Provides effective circuit isolation after disconnection, minimizing the risk of electric shock during maintenance or repair.
• High reliability: Mechanical endurance of 200,000 cycles guarantees long-lasting and trouble-free operation.
• Compact dimensions: A width of 2 modules saves space in the distribution board.
• Easy installation: Screw terminals allow for quick and secure connection of wires with a cross-section from 1.5 mm² to 16 mm².
• Clear indication: Color-coded lever marking makes it easy to identify the circuit status (ON/OFF).
• Wide operating temperature range: The ability to operate at temperatures from -20°C to +70°C ensures flexibility of use.
• Compliance with standards: Meets the requirements of IEC 60947-3, IEC/EN 60669-2 and IEC/EN 60669-4 standards, confirming its safety and quality.
• Low energy consumption: Minimizes power losses in the electrical installation (total power loss for rated current is 2.7W).

The SBN325 switch is a solid choice for anyone who values safety, reliability and ease of use in electrical systems. Its versatility makes it perfect for both new installations and the modernization of existing facilities.
