قاطع عزل الدارات الكهربائية الثلاثي (Hager) موديل (SBN341N) قياس (40A)

The modular design lets you stack or combine multiple units to scale protection as your system grows, without needing extensive rewiring. It also allows bolting or screwing the switch into place for straightforward installation.

Core specs include: 3-pole configuration, current rating up to 40A, voltage rating up to 600V AC, insulation voltage around 500V AC, and a breaking capacity reaching up to 3600A. It’s designed for use in both single-phase and three-phase systems and is listed under IEC 60947.

It's suitable for panel boards in homes and offices, and for protection in small to medium electrical installations. Its three-pole design makes it apt for isolation in both single-phase and three-phase configurations.

Begin with de-energizing the system. Mount the switch using the provided mounting method (bolting or screwing as applicable). Connect the busbars or input/output connections per your panel layout, ensure secure and clean contacts, and verify mechanical alignment before re-energizing.

Yes. The unit is a 3-pole isolator designed to work in both single-phase and three-phase systems, providing reliable isolation and protection across all three lines.

It’s certified in accordance with IEC 60947 and features insulated construction capable of withstanding up to about 500V AC insulation, with a robust design intended for safe operation in electrical panels.

Its modular, stackable design supports scalable protection without extra wiring, and it emphasizes compact size and straightforward mounting. These traits make it particularly convenient for modern spaces and evolving protection needs.

Consider your panel size and space, the current and voltage requirements of your circuit (up to 40A and 600V AC), whether you need modular stacking for future expansion, and the need for a compact, easy-to-install isolation solution that meets IEC 60947 standards.

Routine checks are typically minimal for mechanical isolators. Ensure mounting screws remain tight, contacts are clean, and perform periodic functional tests with proper protective equipment to verify isolation functioning under fault conditions.
