Combined Protection:
Provides protection against overload, short circuits, and earth leakage currents in a single device.
Type A Residual Current Detection:
Detects AC and pulsating DC earth leakage currents — essential for protecting modern appliances with electronic components.
C Curve Tripping:
Ideal for general-use circuits such as lighting, socket outlets, and small motor loads.
Compact 1P+N Design:
Saves space in the distribution board while offering full protection on the live conductor and isolation on the neutral.
Rated Breaking Capacity – 4.5kA:
Suitable for use in low to moderate fault current environments, common in residential and light commercial settings.
Rated Current – 20A:
Designed for circuits requiring up to 20 amps of current.
30mA Sensitivity:
High level of protection against electric shock — trips quickly on earth leakage currents of 30 milliamps.
Neutral Tail Provided:
Facilitates easy and quick connection during installation.
Status Indication Window:
Visual indicator shows ON/OFF/trip status for ease of maintenance and diagnostics.
Test Button:
Built-in test function allows regular safety checks of residual current operation.
DIN Rail Mounting:
Quick and easy installation into standard distribution boards.
Compliance:
Meets IEC 61009-1 standards for RCBO devices.
