## Summary description

Combined residual-current and overcurrent protection device (RCBO) Eaton xPole Home HNB-B20/1N/003, 2-pole, rated current 20 A, B tripping characteristic, residual current sensitivity 0.03 A (30 mA), type AC. Designed to protect circuits against overload, short-circuit and earth-leakage currents. Suitable for residential and light commercial distribution boards to safeguard personnel and wiring.

## Long description

The Eaton xPole Home HNB-B20/1N/003 is a combined residual-current and overcurrent circuit breaker (RCBO) designed for protection of electrical circuits in residential and light commercial installations. This 2-pole device provides both overcurrent protection with a B characteristic curve and earth-leakage detection with a 30 mA sensitivity (type AC), allowing coordinated protection of wiring and people against overloads, short circuits and alternating residual currents.
Advantages
The compact RCBO integrates two protection functions in a single module, saving space in consumer units and simplifying wiring. A B tripping characteristic ensures prompt disconnection for typical residential loads and short-circuit events while maintaining selectivity with downstream devices. The 30 mA residual current sensitivity offers reliable human protection against electric shock and reduces the risk of fire from leakage currents. Eaton xPole design follows industry standards for mechanical and electrical durability, enabling long service life under normal operating conditions.
Suitable for
 Protection of lighting and socket circuits in homes
 Small commercial premises and offices with single-phase loads
 Replacement of separate MCB and RCD units to free DIN-rail space
 New consumer units where combined overcurrent and earth-fault protection is required
Key specifications
 Poles: 2-pole unit for single-phase circuits
 Rated current: 20 A continuous
 Tripping characteristic: B curve (short-circuit trip profile)
 Residual current sensitivity: 0.03 A (30 mA), type AC (responds to alternating residual currents)
 Function: Combined protection against overload, short circuit and earth leakage
 Mounting: DIN-rail compatible compact module for consumer units
How to use
Install the RCBO in the consumer unit on a standard DIN rail in accordance with local electrical regulations and manufacturer installation instructions. Connect the phase and neutral conductors to the designated terminals and ensure correct tightening torques. Use the device to feed the circuit that requires combined earth-fault and overcurrent protection; after installation, test the residual-current function using the built-in test button or a suitable external tester to verify correct operation. Commission only after verifying wiring and continuity, and observe required isolation procedures before any work on the circuit.
Usage recommendations
For reliable operation, verify compatibility with the supply system and downstream protective devices to maintain selectivity. Periodically test the residual-current trip function (usually every 6–12 months) and inspect connections for corrosion or loosening. Replace the device if it fails routine tests or shows signs of mechanical damage. Follow local codes for earthing, bonding and protective device coordination when incorporating this RCBO into an installation.
