Product Overview
What This Model Does
For panel builders and installers, it replaces a conventional MCB or RCCB with a single device that adds reliable earth leakage detection and automatic disconnection, reducing the number of components in a distribution board and simplifying wiring.
Key Benefits
- Protects against electric shock and fire risks from earth leakage currents in three-phase systems
- Combines overcurrent and earth leakage protection in one DIN rail device
- Reduces panel space and wiring complexity by replacing separate MCB and RCCB units
- Operates independently of the power supply, so protection remains active during outages
Who It Is For
- Panel builders integrating protection into distribution boards for industrial or commercial projects
- Electrical wholesalers stocking ELCB devices alongside conventional MCBs and RCCBs
- Solar EPC contractors installing three-phase inverters with required earth leakage protection
- Switchgear assemblers building custom control cabinets with compact protection solutions
- OEM/ODM buyers sourcing a compliant ELCB for integration into their own electrical systems
Problems It Solves
- A separate MCB and RCCB are required for overcurrent and earth leakage protection, increasing panel space and wiring
- Earth faults go undetected in three-phase systems due to lack of dedicated ELCB protection
- Panel builders must manage multiple device types and mounting configurations for protection
- Safety compliance is harder to achieve when protection functions are split across devices
- Faults in three-phase circuits can persist and cause fire or injury without automatic disconnection
Application Scenarios
- Industrial control panels where three-phase motors need both overcurrent and earth leakage protection
- Commercial buildings with three-phase power feeding HVAC systems, pumps, or lighting circuits
- Solar PV systems with three-phase inverters requiring earth fault detection for safety compliance
- Manufacturing equipment where ground faults could cause injury or damage without immediate disconnection
- Data centres and server rooms where a single earth fault could lead to equipment failure or fire
Technical Features

Comparison
How It Compares
| Conventional MCB plus separate RCCB | One device instead of two, reducing panel space and wiring complexity |
|---|---|
| Single-pole ELCB in a three-phase system | Four-pole version ensures all phases are protected simultaneously |
| Zigbee or WiFi smart ELCB | No network dependency; protection works offline, but remote monitoring is not available |
| RCBO with overcurrent and residual protection | Same protection function but with a higher rated current and different trip characteristics |
Use Guide
- Switch on manually and confirm the device holds under normal load before testing
- Test the residual current function using a test button or external tester
- Verify the trip indicator is visible when the device has operated
- Keep the manual handle accessible so the circuit can always be isolated on site
- Replace the device if it trips repeatedly without a clear fault condition
