Isolating switch with independent (impulse) drive, 3-pole, handle on drive shaft RA 250 P3/R Un: 690 V~ In: 250 A Ui: 1000 V 63-822982-061

Isolating switch – reliable power disconnection

This three-pole isolating switch RA 250 P3/R from Apator is a key element ensuring safe and effective disconnection of electrical circuits. Designed for use in both industry and commercial construction, it enables effective isolation of devices during maintenance, repairs or failures. The construction with an independent cam drive ensures smooth and reliable operation, and high strength parameters guarantee long-term operation.

Construction and application

The RA 250 P3/R switch is designed for plate mounting, making it easy to integrate with existing switchboards and control cabinets. Its solid construction and double insulation gap in each current path ensure a high level of safety. Silver-plated contacts of the current paths minimize transition resistance and increase connection reliability. The device is used as a main switch in distribution systems, as well as an isolating element in service and renovation processes. Thanks to the possibility of cooperation with remote drives (available separately), it can be integrated with automation and remote control systems.

Key features and benefits

• High reliability: Construction based on proven solutions and high-quality materials guarantees trouble-free operation for a long time.
• Safety of use: Double insulation gap ensures complete disconnection of the circuit, minimizing the risk of electric shock during service work.
• Easy installation: Plate mounting allows easy integration with existing electrical installations.
• Adapted to difficult conditions: Possibility of installation in closed rooms without dust, corrosive and explosive gases, and in moderate, tropical and marine climates.
• High short-circuit resistance: Rated conditional short-circuit current Iq is 8 kA, which ensures effective protection of the installation against the effects of overloads and short circuits.
• Versatility: Can be used as a main, isolating or service switch.
• Durability: Made of high-quality materials ensures long device life even with intensive use.
• Rated current: Rated continuous current Iu is 250 A, allowing it to be used in circuits with high power consumption.
• Independent cam drive: Ensures smooth and reliable operation of the switching mechanism, regardless of the speed of the movement performed.

The RA 250 P3/R switch is characterized by a rated operating voltage of 690 V~, a rated continuous current of 250 A and the ability to withstand short circuits with a value of 8 kA. It has three poles and a screw connection of the main contacts, and its degree of protection (IP) of the front is IP00.

The RA 250 P3/R switch is a solid and reliable solution for professionals and end-users looking for a safe and effective way to disconnect power in their electrical installations.
