Modular disconnecting switch 4P 100A 400VAC SBN490

Modular isolating switch – safety and functionality in one

This four-pole isolating switch with a rated current of 100A and a voltage of 400VAC is a reliable element of any electrical installation. It is used to safely disconnect circuits, both during normal operation and in emergency situations. Its solid construction and high durability guarantee long-lasting and trouble-free operation.

This switch finds application in electrical distribution boards, providing effective circuit isolation during maintenance, repairs or modernization of installations. It is ideal for both professional installers and end-users looking for a safe and convenient solution for managing electrical energy.

Characteristics and application

The device is characterized by a high short-circuit breaking capacity (1.692 kA) and a rated switching capacity (1.2 kA), which ensures effective protection against the effects of overloads and short circuits. The width of the switch, 4 modules, allows for easy mounting in standard modular distribution boards. The IP20 protection class provides protection against accidental contact.

Thanks to its parameters, this switch is perfect in installations:

• Home – protection of circuits with high power consumption.
• Industrial – disconnecting machines and equipment during servicing.
• Commercial – ensuring safety in public buildings.
• In workshops - separating devices from the power supply during repairs.

Advantages and product features

• High reliability: Ensured by a solid construction and high-quality materials.
• Safety: Effective protection against overloads and short circuits thanks to high short-circuit breaking parameters.
• Easy installation: Compact dimensions (4 modules) facilitate installation in standard distribution boards.
• Versatility: Wide application in various types of electrical installations – home, industrial and commercial.
• Durability: Mechanical endurance of 40,000 cycles guarantees long-term use.
• Clear lever marking: Color differentiation of the lever facilitates identification of the switch function compared to other modular protective devices for the installation.
• Biconnect terminals: Allow easy connection of fork-type comb busbars (for models from 40A to 125A).
• Low energy consumption: Isolating switches are characterized by low power losses, which translates into energy savings.
