Apator RA250 P3N/RiN 3-Pole Switch Disconnector with Independent Operation, 250A, 690V

The Apator RA250 P3N/RiN is a high-performance 3-pole switch disconnector engineered for secure power circuit isolation in demanding industrial environments. This device features an independent operation mechanism, ensuring consistent switching performance regardless of the speed at which the handle is operated. Designed for reliability and safety, it serves as a critical component in power distribution systems, allowing for the manual disconnection of electrical circuits under load.

Advantages

The primary advantage of the Apator RA250 P3N/RiN is its robust construction, which provides long-term durability in harsh industrial conditions. The independent operation mechanism guarantees that the contact opening and closing speeds are constant, which significantly reduces arc duration and enhances the lifespan of the contacts. Its compact design allows for efficient space utilization in electrical cabinets, while the shaft-mounted handle provides ergonomic and intuitive control for operators.

Suitable for

• Industrial power distribution panels
• Main power supply isolation
• Control and protection of electrical motors
• Emergency shutdown systems in manufacturing facilities

When it may not be suitable

This switch disconnector is not intended for use in environments with extreme moisture, corrosive gases, or explosive atmospheres unless housed in an appropriately rated protective enclosure. It is also not suitable for applications requiring remote automated switching, as it is designed for manual operation.

Key specifications

• Number of poles: 3
• Rated operational current: 250A
• Rated operational voltage: 690V AC
• Rated insulation voltage: 1000V
• Operation type: Independent manual operation
• Mounting type: Shaft-mounted handle

How to use

The device should be installed by a qualified electrician within a suitable electrical enclosure. The switch is mounted onto the panel, and the shaft-mounted handle is attached to the mechanism to allow for external operation. Once installed, the switch is operated by turning the handle to the desired position to either connect or disconnect the power supply. Ensure that all electrical connections are tightened to the specified torque values before energizing the circuit.

What to consider before purchase

• Verify that the 250A current rating matches your circuit requirements.
• Ensure the installation space is sufficient for the device dimensions.
• Confirm that the shaft length is compatible with your specific enclosure depth.
• Check that the environmental conditions meet the manufacturer's operational standards.

Usage recommendations

Regularly inspect the switch for any signs of wear or loose connections during scheduled maintenance intervals. Ensure that the handle mechanism moves freely and that the enclosure remains clean and free of debris to maintain optimal performance.
