## Summary description

FF PSA-263 is a modular transfer switch designed for safe switching between mains and generator power. It is a 2-pole device rated at 63 A, suited for interrupting and routing single-phase circuits in backup-power installations. The compact modular format allows DIN-rail mounting and integration into distribution boards for residential or light-commercial standby power applications.

## Long description

FF PSA-263 is a modular transfer switch engineered for safe and reliable switching between mains and generator supply in single-phase backup-power installations. This 2-pole device is rated for 63 A continuous current and is intended to interrupt and route live and neutral conductors in residential or light-commercial standby power systems. Its compact modular design is compatible with DIN-rail mounting and integration into distribution boards, allowing neat installation inside consumer units and control cabinets.
Advantages
The design provides clear separation between mains and generator circuits, reducing risk of backfeed and simplifying system topology. The modular housing saves space on the DIN rail and permits easy replacement or expansion within existing distribution panels. Being a 2-pole 63 A device, it supports common single-phase emergency generator setups while meeting practical current requirements for many household and small-business loads. Its construction supports straightforward wiring and maintenance.
Suitable for
 Residential single-phase emergency power transfer between mains and a backup generator
 Small commercial premises with on-site standby generation for lighting and essential circuits
 Integration into distribution boards and DIN-rail control cabinets
 Applications requiring a compact, replaceable modular transfer switch for routine maintenance
Key specifications
 Poles: 2-pole switching suitable for live and neutral conductors
 Rated current: 63 A continuous
 Function: manual or automatic transfer switching between two power sources (mains and generator)
 Mounting: DIN-rail modular format for distribution boards
 Application: single-phase backup power installations for residential and light-commercial use
 Form factor: compact modular housing designed for limited panel space
How to use
Install the transfer switch on a standard DIN rail inside the distribution board following local electrical codes and safety regulations. Connect the incoming mains and generator supply lines to the designated source terminals and route the protected load circuits through the output terminals. Ensure all connections are tightened to the manufacturer's recommended torque and verify correct pole identification before energizing. Commissioning should include functional verification that the switch correctly isolates one source before connecting the other to prevent parallel connection of mains and generator. If configured for automatic operation, test the control wiring and any monitoring devices according to the system design.
Usage recommendations
Use the device only within its rated current and application scope. Regularly inspect terminal connections and mounting integrity, and perform periodic functional tests of the transfer operation. For any installation involving automatic transfer control or protective coordination, consult a qualified electrician to ensure compatibility with upstream protection devices and generator control systems.
