Modular isolating switch 3P 40A 400VAC SBN340

Modular isolating switch – safety and control in your installation

This three-pole isolating switch with a rated current of 40A is a key element of any electrical installation, providing safe disconnection of circuits and protection against overloads and short circuits. The SBN340 from Hager is a reliable solution for both professional installers and end users who value safety and functionality.

Functionality and application

The isolating switch is used to completely disconnect the circuit from the power supply, allowing for safe maintenance, servicing or repair work. Its design allows for reliable and quick disconnection of current-carrying conductors, minimizing the risk of damage and ensuring the protection of personnel working on the installation. This makes it indispensable in distribution boards, connection boxes and anywhere where safe isolation of a section of the installation is required.

Construction features and advantages

• Compact dimensions: A width of only 3 modules allows for efficient use of space in the distribution board.
• High reliability: Made of high-quality materials, guarantees long-lasting and trouble-free operation.
• Safety of use: Rated switching capacity of 0.846 kA and short-circuit strength (Icw) of 0.6 kA provide effective protection against the effects of overloads and short circuits.
• Easy installation: Modular design facilitates quick and easy mounting on a TH35 rail.
• Versatility: Suitable for operation with AC 400V and current of 40A, making it an ideal solution for a wide range of applications.
• Durability: Withstands up to 60,000 mechanical cycles, confirming its durability and reliability.
• Screw terminals: Allow for solid and secure connection of conductors with a cross-section from 2.5 mm² to 25 mm².
• Protection class IP20: Provides basic protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.

The switch has three poles, and its rated current is 40A at a rated voltage of 400V. The rated switching capacity is 0.846 kA, and the width of the device is 3 modules, and the installation depth is 68 mm.
