Current monitoring relay, 0.3 - 15 A, 24 - 240 V AC/DC EMR6-I15-B-1 184755

Current Monitoring Relay – Reliable Installation Protection

The EMR6-I15-B-1 current monitoring relay is an advanced device designed for comprehensive protection of electrical installations. It provides overcurrent and undercurrent control, protecting circuits from overloads, short circuits, and malfunctioning devices. Its versatility and wide measurement range (0.3…15 A) make it an ideal solution for both professional installers and end-users who care about safety and power supply reliability. The device is a direct replacement for the outdated EMR4-I15-1-B model (cat. no. 106944), making it easier to modernize existing systems.

Functionality and Application

The EMR6-I15-B-1 relay offers advanced current monitoring functions, including undercurrent and overcurrent control for single-phase circuits. This makes it possible to detect both excessive and insufficient current draw, allowing for a quick response in the event of a failure or malfunction of devices. A wide supply voltage range (220…240 V AC) and no need for an external power source simplify installation and operation. The device finds application in:

• Protection of electric motors against overload and short circuit.
• Monitoring the operation of heating and air conditioning devices.
• Securing lighting installations against failures.
• Industrial automation systems requiring precise load monitoring.
• Applications requiring detection of a decrease or increase in current consumption by receivers.

Technical Characteristics and Benefits

The relay's construction is based on solid components, guaranteeing its long-lasting and reliable operation. The device dimensions (22.5 mm width, 85.6 mm height, 103.7 mm depth) allow for easy integration with existing electrical panels. Screw connection ensures secure and durable electrical connections. Adjustable time delay on power-on and power-off (0.1 s - 30 s) allows you to adapt the relay's operation to specific application requirements – particularly important when starting devices with motors that generate high inrush currents. Two programmable current setting thresholds (0.3…1.5 A and 3…15 A) increase the device's flexibility and allow it to be used in various work scenarios. This allows you to precisely set the limits at which the relay should react, minimizing the risk of false alarms or overlooking a real threat to the electrical installation.
