Mains-generator changeover switch, 63A, 4-pole I-0-II SF463

Modular switch for reliable circuit switching

This four-pole modular switch from Hager, with a rated current of 63A, is a robust solution for switching power and control circuits. The I-0-II design (on-off-on) provides flexibility in energy management, and the compact dimensions (8 modules wide) allow for easy mounting in standard distribution boards. The device is ideal for both professional installers and end-users looking for a reliable and safe solution.

Functionality and application

The SF463 switch is used in electrical installations in residential, commercial and industrial buildings. It works perfectly in situations requiring switching between different power sources, e.g. mains and generator (mains-generator). Thanks to the possibility of selecting the I-0-II position, it allows for convenient control of electrical circuits. Withstand to short-circuit current up to 6kA provides additional safety for the installation.

Key features and benefits

• Versatility: Ability to switch between different power sources (I-0-II).
• Safety: Short-circuit withstand up to 6kA protects the installation from damage.
• Compactness: 8 module width makes it easy to install in tight distribution boards.
• Durability: High quality workmanship guarantees long-lasting and trouble-free operation.
• Universality: Suitable for use in residential, commercial and industrial buildings.
• Adapted to various loads: Rated current of 63A allows for servicing a wide range of electrical devices.
• Solid construction: Ensures stable and reliable operation for a long time.
• Easy installation: Enables quick and trouble-free installation in existing distribution boards.

Switch operating characteristics

The SF463 switch is designed to operate in standard electrical installations with a voltage of 400V and a frequency of 50/60 Hz. It provides a high level of insulation (500V) and surge resistance (4000V), which guarantees safety of use. It allows connection of wires with a cross-section of up to 25mm² (rigid) or 16mm² (flexible), and the IP20 protection degree provides protection against finger contact and solid objects larger than 12.5 mm – which is suitable for mounting inside distribution boards.
