The SNS Series with residual current protection, likely referring to a specific product line of Residual Current Circuit Breakers (RCCBs) or Residual Current Devices (RCDs), are used to detect and interrupt electrical circuits in case of a fault such as current leakage to ground (earth). This helps prevent electric shocks and fires. These devices are crucial for safety in both residential and industrial settings, offering protection against electrocution and damage to equipment.

Key Uses and Benefits:

Protection against Electric Shock: RCCBs/RCDs quickly disconnect the power supply when they detect a leakage current, significantly reducing the risk of electric shock.

Fire Prevention: By interrupting the circuit when a fault is detected, they help prevent electrical fires.

Safety in Various Environments: These devices are used in homes, offices, industrial plants, and other areas where electricity is used.

Compliance with Regulations: RCCBs/RCDs often meet or exceed safety standards, ensuring compliance with electrical regulations.

Enhanced Safety Features: Some devices offer additional features like automatic testing to ensure proper function and quick tripping times.
