Residual current device RH197M, 30 mA to 30 A, 220 VAC 240 VAC 56517

Residual Current Device (RCD) for AC circuit protection

The RH197M residual current device is a reliable device designed to protect people and electrical installations from the effects of leakage and earth fault currents in alternating current circuits. It provides a quick response to dangerous situations, minimizing the risk of electric shock and equipment damage. It is a key safety element in any electrical system, both in domestic and industrial applications.

Characteristics and application

This device is characterized by a wide setting range of the differential current, from 0.03 mA to 30 mA, which allows you to adjust the sensitivity to specific application needs. It can be used in various circuits, including lighting, socket and electrical appliance power circuits. Thanks to the screw connection, installation is simple and convenient for installers. The device requires an external AC power source with a voltage of 220-240V at a frequency of 50-400 Hz.

• Protection against electric shock: Fast circuit disconnection in the event of a leakage current protects users from dangerous electric shock.
• Installation protection: Prevents damage to devices and cables caused by short circuit to ground or overload.
• Wide range of applications: Ideal for securing circuits of various purposes - from lighting to powering electrical appliances.
• Adjustable sensitivity: Possibility to adjust the tripping threshold (30mA) to the specifics of the protected circuit.
• Solid construction: Ensures long-lasting and reliable operation in various environmental conditions.

Technical specifications and construction

The RH197M device has two changeover contacts, which allows its integration with various control and signaling systems. Its compact dimensions (71.2 mm width, 98.7 mm height and 65.8 mm depth) allow for easy installation even in limited space. The device does not have a fault memory function or a differential current indicator, which simplifies its operation and diagnostics. The rated switching current is 8A, and the maximum permissible time delay when applying power is 4.82 seconds - this ensures stable operation of the device after power-up. The set current value is in the range of 0.015 mA to 60 mA, providing flexibility in configuring the protection.
