Phase sequence relay, 200 - 500 V AC EMR6-F500-G-1 184789

Phase sequence relay – reliable installation protection

The EMR6-F500-G-1 relay is a device designed to monitor the phase sequence in power networks. Its task is to ensure safe and uninterrupted operation of electrical equipment by detecting irregularities in the phase sequence and loss of one of the phases. This is crucial for protecting motors, transformers and other sensitive receivers from damage caused by incorrect connection or network failure. The device is particularly useful in industrial applications, construction and anywhere requiring high power supply reliability.

Functionality and application

The EMR6-F500-G-1 relay offers comprehensive protection thanks to its built-in phase sequence control and phase failure detection functions. Therefore, in the event of power supply problems, the device reacts immediately, disconnecting the load and preventing more serious failures. A wide range of supply voltage (200…500 V AC) makes the relay compatible with various electrical systems. Mounting on a DIN rail IEC/EN 60715 simplifies installation and integration with existing infrastructure.

• Phase sequence control: ensures correct connection of three-phase receivers, which is crucial for their correct operation and durability.
• Phase failure detection: protects devices from damage in the event of loss of one of the supply phases.
• Wide voltage range: allows the relay to be used in various electrical networks (200-500 V AC).
• Screw connection: ensures a secure and durable connection of wires.
• Compact dimensions: 22.5 mm width, 85.6 mm height and 103.7 mm depth allow mounting in limited space.
• Compliance with standards: ensures the safety and reliability of the device (IEC/EN 60255-6, EN 61557).

Technical parameters and construction

The EMR6-F500-G-1 relay is characterized by a solid construction and high quality workmanship. The housing with a protection class of IP20 protects the internal elements from environmental influences. The device does not require an external power source, which simplifies installation and reduces operating costs. Two switchable contacts allow flexible configuration of control circuits and alarm signaling. It is worth noting that there is no need to adjust the time delay – the relay operates immediately after detecting an irregularity, minimizing the risk of damage to connected devices. The rated switching current is 4A, ensuring compatibility with most standard loads.
