The Schneider current measurement relay is designed to monitor electrical circuits for overcurrent or undercurrent conditions, providing protection and control. It can be adjusted to trigger a response when current levels fall outside of a specified range.
Yes, this relay is capable of measuring both AC and DC currents within its specified measurement range.
The relay offers an adjustable time delay ranging from 0.05 to 30 seconds, allowing for customisation based on the specific application requirements.
The relay has multiple current measurement ranges, including 1 to 5 A, 3 to 15 A for both AC and DC, and 300 to 1500 mA for AC and DC, providing versatility for different monitoring scenarios.
The relay is equipped with 2 changeover (C/O) contacts, which can be used to switch between two circuits, depending on the measured current.
The maximum switching voltage for the relay is rated at 440 V AC, which is suitable for a wide range of industrial applications.
The relay has dimensions of 45 x 80 x 78 mm, making it suitable for DIN rail mounting in standard industrial enclosures.
The current threshold setting can be adjusted on the relay itself, with a hysteresis range of 5 to 30% of the current threshold setting, allowing for precise control of the switching point.
The rated insulation voltage (Ui) for the relay is 500 V, conforming to IEC standards, which helps to ensure safe operation within electrical systems.
The relay boasts a mechanical durability of 30 million cycles, indicating its ability to withstand a high number of operations over its lifespan.
