Insulation monitoring relay, 0 - 690 V AC, 0 - 1000 V DC EMR6-RC690 184775

Insulation monitoring in AC/DC networks

The EMR6-RC690 insulation monitoring relay is a reliable device designed for continuous monitoring of insulation resistance in AC and DC power systems. It provides protection against dangerous leakage currents, which can lead to failures and hazards to people. The device is versatile and finds application in both industrial and commercial installations.

Versatile application and easy configuration

The EMR6-RC690 relay offers a wide range of voltage measurement – from 0 to 690 V AC and 0 to 1000 V DC, making it suitable for various applications. The ability to adjust the impedance setting value (1…100 kOhm and 1…200 kOhm) allows for precise adjustment of the device's sensitivity to specific operating conditions of the installation. No need for an external power supply simplifies installation and reduces installation costs.

Solid construction and compliance with standards

The device is characterized by compact dimensions (45 mm width, 78 mm height and 100 mm depth) and a solid construction, which ensures its durability and reliability in harsh industrial conditions. Made of high-quality materials, it provides long-lasting and trouble-free operation. The relay has screw connections, guaranteeing secure and stable electrical connections. It is a replacement for the EMR5-RC690 relay (cat. no. 153445), which facilitates the modernization of existing installations.

Key features:

• Wide voltage range: Monitoring of both AC (0-690V) and DC (0-1000V) networks.
• Sensitivity adjustment: Two impedance setting ranges allow for precise adaptation to a specific application.
• No external power supply: Simplified installation and reduced installation costs.
• Compact dimensions: Easy integration with existing systems.
• Screw connections: Ensure stable electrical connections.
• Versatility: Suitable for mixed circuits (AC/DC).
• Replaces older model: Compatible with installations using EMR5-RC690.
• Maximum monitored circuit capacitance: Up to 20 µF - allows monitoring of circuits with capacitors.

Thanks to these features, the EMR6-RC690 relay is an optimal solution for professionals involved in the installation and maintenance of electrical systems, as well as for end-users looking for reliable protection of their devices and installations against the effects of insulation damage.
