Modular isolating switch 2P 63A 400VAC SBN263

Isolator switch – safety and reliability in your installation

This modular Hager SBN263 isolator switch is a key element of any electrical installation, providing effective circuit disconnection and protection against overloads and short circuits. The device is designed to operate in AC systems with a voltage of 400V and a rated current of 63A, making it an ideal solution for both installers and end users.

Solid construction and high quality workmanship guarantee long-lasting and trouble-free operation. The switch is characterized by resistance to 5000 electrical switching cycles and as many as 60000 mechanical cycles, which confirms its reliability even in heavily used installations. Compact dimensions (width 2 modules, depth 68 mm) make it easy to install in switchboards with limited space.

Application and functionality

The SBN263 isolator switch is widely used in electrical switchboards, where it serves to safely disconnect individual circuits during maintenance, repair or modernization of the installation. The two-pole design allows disconnection of two phases, providing complete circuit isolation. The rated switching capacity at 1.332 kA provides effective protection against the effects of short circuits. The IP20 degree of protection protects against accidental contact, increasing safety.

Key product features:

• Rated current: 63A – suitable for most standard circuits.
• Rated voltage: 400V – compatible with typical power grids.
• Number of poles: 2 – allows disconnection of two phases.
• Short-circuit switching capacity: 1.332 kA – high resistance to short-circuit currents.
• Mounting: Easy mounting on DIN rail thanks to standard dimensions (2 modules).
• Durability: Long service life thanks to the high number of switching cycles (5000 electrical, 60000 mechanical).
• Safety: IP20 protection degree provides protection against accidental contact.
• Short-circuit strength (Icw): 0.945 kA - resistance to short-term current surges.

This isolator switch is an investment in the safety and reliability of your electrical installation, which will meet the expectations of both professional installers and demanding end users.
