RCD Type & Tripping Sensitivity:

RCD Type Characteristics
Type AC RCDs	Detect slowly increasing sinusoidal AC residual currents.
Type A RCDs	Detect AC leakage currents and pulsed DC leakage currents below 6mA.
Type S, G/SI RCDs	Ensure tripping response to sinusoidal AC residual currents and effectively detect/trip pulsed DC residual currents, whether increasing suddenly or slowly.
Tripping Sensitivity (mA)
10mA	Provides a higher level of protection for the human body; used in humid environments like swimming pools and bathrooms.
30mA	Most commonly used protection level in homes and commercial buildings for socket protection.
100mA	Used for equipment protection (e.g., AC systems, industrial equipment) where personal protection requirements are less strict.
300mA	Mainly used for fire protection, distribution boards, and general protection of large electrical equipment.

Tripping Time & Breaking Characteristics:

Tripping Time Categories
Instantaneous (AC, A)	Quickly disconnects circuits (≤300ms) to protect people from electric shock.
Short time delay (G/SI)	Shorter trip times (10-300ms) to minimize damage where rapid power outage is required for equipment.
Selective S	Longer tripping time (130-500ms) allowing downstream RCDs to trip first, avoiding unnecessary upstream power outages.
