Phase sequence control relay iRCP A9E21180

Phase control and installation safety

The Acti9 iRCP A9E21180 phase sequence relay is a reliable device that monitors the correct voltage and phase sequence in three-phase networks. Its main task is to protect the electrical installation and connected devices from the effects of phase failure or incorrect phase sequence. This is a key solution to ensure continuity of operation and safety, especially for sensitive receivers such as electric motors.

Functionality and application

The device signals loss or change of phase sequence, allowing for a quick response and preventing failures. The relay has one changeover contact, which can be used to disconnect the power supply to the protected circuit or to activate an alarm. This gives the installer confidence that potential problems will be detected and minimized. It finds application in electrical switchboards, control cabinets and anywhere where protection against irregularities in three-phase power supply is required.

Characteristics and benefits

• Versatility: The relay works with a supply voltage of 400V AC (50/60 Hz), making it a universal solution for most installations in Poland.
• Precise measurement: The voltage measurement range from 0.15V to 10V ensures accurate monitoring of network parameters.
• Fast response: The maximum time delay in case of power failure is only 0.3 seconds, guaranteeing quick detection of the problem.
