4-pole power source transfer switch 125 A in ABS housing PRZK-4125\OBA

Power source switch – reliable switching in your installation

This four-pole power source switch with a rated current of 125A is a robust solution for safe and efficient power switching. Made of durable plastic (ABS), it provides durability and resistance to mechanical damage. Designed for both professional and demanding users, it guarantees reliable operation in various conditions.

Design and application

The switch is designed for panel mounting, making it easy to integrate with existing electrical installations. The housing made of ABS provides protection against external factors, and the IP65 protection class guarantees resistance to dust and moisture – an ideal choice for industrial environments or workshops. The switching mechanism based on a knob ensures precise and convenient operation. The device is complete, supplied in a housing, which eliminates the need for additional mounting elements.

Advantages and benefits

• High reliability: Rated continuous current of 125A ensures stable operation even under heavy loads.
• Safety of use: IP65 protection class protects against dust and moisture, minimizing the risk of failure and electric shock.
• Easy installation: Designed for panel mounting, which simplifies installation and integration with existing systems.
• Durable construction: Housing made of plastic (ABS) provides resistance to mechanical damage and corrosion.
• Versatility: Can be used in various environments – from workshops to industrial installations.
• Full functionality: Has 4 poles and a "0" position, allowing complete disconnection of the circuit.
• Resistance to external conditions: Withstands vibrations, shocks and cyclic changes in humidity and temperature (according to IEC standards).

Technical parameters in practice

The switch is characterized by high resistance to short-circuit currents (up to 25 kA when using a gL/gG 125 A fuse), which increases the safety of the installation. Its mechanical durability is 8000 cycles, and the switching durability is 1000 cycles, which guarantees a long service life of the device. The possibility of connecting cables with a cross-section of 25-70 mm² provides flexibility in choosing the appropriate cables. The rated insulation voltage U_i is 690V and the impulse voltage U_imp is 8kV - parameters important for ensuring safe operation in various electrical installations.
