HAGER SF463 Interruttore automatico modulare 4 poli 63A 400V AC I-0-II

Manual transfer between two power sources or isolation of a circuit is often a challenge in industrial and commercial electrical installations. The HAGER SF463 modular power switch solves this by providing a robust, panel-mounted solution for switching between two independent supplies or disconnecting a 3-phase + neutral circuit. With a 63 A rated current and 400 V AC rating, it handles demanding loads while fitting neatly on a standard DIN rail.

Who is it for

This switch is ideal for electricians, panel builders, and facility managers who need a reliable changeover or isolation device in distribution boards, control cabinets, or machine power supplies. It suits applications requiring a visible break and manual control, such as generator changeover, motor isolation, or supply selection.

Main features

• 4-pole (3P+N) configuration with I-0-II switching positions for two-source transfer or isolation.
• 63 A rated current and 400 V AC rated voltage for heavy-duty circuits.
• Compact modular design: only 4 modules wide (70 mm), mounts on standard DIN rail.
• Manual toggle operation with clear position indication for safe switching.
• High electrical durability: 10,000 cycles; mechanical durability: 20,000 cycles.
• Connection capacity up to 25 mm² rigid or 16 mm² flexible conductors.
• IP20 protection on front face (IP40 with terminal covers) for indoor installations.
• Complies with IEC/EN 60947-3 for low-voltage switchgear.

Tips

For installations where terminal covers are used, ensure they are properly fitted to achieve IP40 protection. Always verify that the switch is in the '0' (off) position before making or breaking connections. When selecting conductors, adhere to the specified connection capacities to maintain safe operation.
