Disconnect switch On/Off In=100A P=50kW P3-100/EA/SVB-SW 062603

Main disconnector – reliable power disconnection

This On/Off disconnector with a rated current of 100A and a power of 50kW is a robust solution for safely disconnecting electrical installations. Designed for both industrial and commercial building applications, it provides effective protection against overload and short circuit. The device's construction, compliant with IEC/EN 60947-3 standards, guarantees reliability and long life.

Functionality and application

The P3-100/EA/SVB-SW disconnector serves as a main disconnector and a maintenance disconnector. Its solid construction and high resistance to environmental conditions (IP65) make it an ideal choice for demanding applications. The ability to lock with three padlocks further increases security, preventing accidental or unauthorized switching on. Panel mounting (4-hole) simplifies integration with existing electrical infrastructure.

• Safety: Provides effective disconnection of the circuit in emergency situations or during maintenance work.
• Versatility: Suitable for installations with a voltage of 690V AC, both in industrial and commercial buildings.
• Durability: Made of high-quality materials, resistant to mechanical damage and weather conditions.
• Easy installation: Designed for panel mounting, which simplifies the installation process.
• Locking: Possibility of protection against accidental switching on with padlocks.
• Compliance with standards: Meets the requirements of IEC/EN 60947-3 and VDE 0660 standards, confirming its safety and reliability.

Technical characteristics and construction

The disconnector is characterized by three poles and a screw connection of the main contacts. It is equipped with a black handle with a locking ring, which facilitates operation and provides additional safety. The switching capacity at 400V is 55kW, and the rated continuous current (Iu) is 100A. The device has a degree of protection of IP65 on the front side, which protects against access to live parts and against the influence of dust and moisture. The locking mechanism ensures a stable position of the contacts after switching off. The rated short-time withstand current Icw is 2kA and the conditional short-circuit current Iq is as high as 80kA - which proves high resistance to short-term overloads.

The device operates at a rated operating voltage from 690 to 690V AC, and its rated operating power for AC-3 at 400V is 37kW, while for AC-23 it is 55kW. The degree of protection (NEMA) is 12.

This disconnector is a solid choice for professionals and users looking for a reliable solution for disconnecting power in various electrical applications.
