Type A (Standard RCD)

Type A RCDs are the most common type used in residential and commercial settings. They are designed to detect earth faults and provide protection against electric shock and fire hazards. Typically rated at 30mA, they are suitable for general applications where the risk of electric shock is moderate. When purchasing, B2B buyers should consider installation costs and compliance with local electrical safety standards, ensuring that the RCD meets the specific needs of their project.

Type B (Type A + DC)

Type B RCDs extend the functionality of Type A devices by offering sensitivity to both AC and DC residual currents. This makes them particularly useful in applications such as solar energy systems and electric vehicle charging stations, where DC faults may occur. Buyers must weigh the higher cost against the safety benefits, especially in environments where DC faults are a concern. Compliance with specific regulations for renewable energy systems is also a key purchasing consideration.

Type C (High Sensitivity)

Type C RCDs are designed for critical environments such as hospitals and laboratories, where the risk of electric shock is significantly heightened. With trip thresholds as low as 10mA, these devices provide enhanced safety but may lead to nuisance tripping if not correctly specified. B2B buyers should evaluate the operational environment and potential for false alarms when selecting this type, as well as the device’s compatibility with existing electrical systems.

Type D (Selective RCD)

Selective RCDs are engineered for coordination with upstream protective devices, making them ideal for industrial settings and large facilities. They minimize unnecessary tripping by ensuring that only the affected circuit is disconnected in the event of a fault. While they offer significant advantages in complex installations, buyers should consider the increased complexity and potential higher installation costs. Proper planning and knowledge of the electrical layout are crucial for effective implementation.

Combined RCD (MCB + RCD)

Combined RCDs integrate the functionalities of both Miniature Circuit Breakers (MCBs) and RCDs, providing a space-saving solution for smaller installations. They are particularly useful in residential and light commercial applications where space is limited. However, buyers should be aware that while they offer convenience, they may lack some dedicated RCD features, and their performance in high-demand situations may not be optimal. Understanding the specific needs of the installation is essential for making the right choice.
