Residual current circuit breaker RH99P with automatic reset 0.03-30A 56290

Differential relay RH99P is a reliable device used to protect against leakage currents and ground faults in electrical circuits. It finds application in both mixed installations and in protecting electrical devices from damage caused by differential currents. Its construction based on clamp terminals ensures convenient and quick installation, and the adjustable setting current allows for precise adaptation to the specific needs of the installation.

Features and application

The RH99P relay is characterized by a wide setting range of the differential current, from 0.03 mA to 30 A, which enables its use in various applications. This makes it a universal solution for both installers and end-users. The device is powered by AC/DC voltage in the range of 12-48V, which provides flexibility in choosing the power source. Automatic reset after activation facilitates operation and minimizes downtime in installation operation.

Advantages and benefits

• Versatility: Possibility of use in mixed circuits thanks to the wide setting range of the differential current (0.03 mA – 30 A).
• Power supply flexibility: Support for AC/DC voltage (12-48 V) facilitates integration with various power systems.
• Automatic reset: Allows for quick restoration of installation operation after eliminating the cause of activation.
• Compact dimensions: Height 72 mm, width 72 mm and depth 78 mm allow for mounting in limited space.
• Easy installation: Clamp terminals ensure quick and secure connection of wires.
• Wide operating frequency range: Operates stably in the frequency range of 50-400 Hz.
• Compliance with standards: Ensures safe and reliable operation in accordance with applicable standards (information about specific standards should be checked in the technical documentation).

Construction and parameters

The RH99P relay has one normally open and one normally closed contact, which allows its integration with various control and signaling systems. The lack of a fault memory function means that after automatic reset, the device is ready to operate again without the need for manual reset. The device does not have detachable terminals, which simplifies installation and ensures a durable electrical connection. The rated inrush current is 8A, which allows for safe starting of connected devices.
