Isolator switch with auxiliary contact 4-pole 40A SA440

Isolator switch – reliable disconnection and installation safety

This 4-pole isolator switch with a rated current of 40A is a key element of any electrical installation, providing safe and effective disconnection of circuits. Equipped with an auxiliary contact, it offers additional control and circuit status signaling capabilities. Its modular design simplifies installation and integration with existing distribution boards.

Functionality and application

The switch is designed to isolate electrical circuits, ensuring complete safety during maintenance, repairs or modernization of the installation. The auxiliary contact allows connection to control systems, signaling the circuit disconnection status. A width of 4.5 modules allows for optimal use of space in the distribution board. It will work in both domestic and industrial installations where reliable disconnection of power is required.

Characteristics and benefits

• Safety first: Provides effective circuit isolation, protecting service personnel and users from electric shock.
• Versatility: The auxiliary contact expands the functionality of the device, enabling integration with control and signaling systems.
• Compact dimensions: A width of 4.5 modules minimizes the space occupied in the distribution board, which is particularly important in limited spaces.
• Durability and reliability: Made of high-quality materials, it guarantees long-lasting and trouble-free operation.
• Easy installation: The modular design simplifies quick and easy mounting on a TH35 rail.
• Wide voltage range: Suitable for operation in AC networks with a rated voltage of 230-415V.
• IP20 protection class: Provides protection against finger contact and against the ingress of solid objects larger than 12.5 mm.
• Installation switches: Color differentiation of the lever from the rest of the modular apparatus ensures easy identification of the device's function.
• Reliable operation: The Quick break switching mechanism ensures safe disconnection of the device under load.
• Biconnect terminals: Allow easy connection of fork comb bars (for conductors from 40A).

The SA440 isolator switch is a solid solution for professionals and demanding users who value safety, reliability and functionality in one device.
