Changeover switch network-generator, 4-pole, 63 A PSA-463

Modular switch for reliable power management

This 4-pole network-generator switch PSA-463 is a key device in systems ensuring uninterrupted power supply. Its switching program based on 1-0-2 allows for flexible connection to two power sources or complete disconnection of the circuit – an ideal solution in emergency situations or during maintenance work. The switch finds application both in public buildings (hospitals, fire stations) and in home installations where uninterrupted power supply is a priority.

Functionality and application

The PSA-463 switch allows for efficient switching between two power lines, which is particularly important in the event of a mains failure. The ability to connect to a generator ensures the continuity of critical circuits. The device is designed for mounting on a TH-35 rail, which facilitates its integration with the existing electrical infrastructure. Thanks to its solid construction and high-quality materials, the switch guarantees reliable operation for a long time.

Construction features and parameters

The housing made of durable plastic provides adequate insulation and protection against mechanical damage. Screw terminals allow connection of wires with a cross-section of up to 16 mm², which provides flexibility in choosing the appropriate cables. The switch is characterized by high electrical endurance (5000 cycles) and mechanical endurance (15000 cycles), which confirms its reliability in demanding working conditions. The IP20 degree of protection provides protection against accidental contact. It is worth noting the compact dimensions of the device – it occupies only 4 modules (70 mm) on the DIN rail, which allows saving space in the switchgear cabinet. The rated current at 63A allows protection of circuits with higher power consumption.
