## Summary description

CNC EL240319 is a 3P+N residual-current circuit breaker with integrated overcurrent protection, rated 63 A and 230 V. Designed to combine earth leakage detection with short-circuit and overload protection, it is suitable for protecting three-phase systems with neutral in residential, commercial or light industrial installations. Provides compact DIN-rail mounting and manual reset for safety and maintenance.

## Long description

CNC EL240319 is a combined protective device for three-phase with neutral (3P+N) AC circuits. It provides automatic overvoltage and undervoltage protection and integrates residual-current and overcurrent protection functions for circuits rated up to 63 A at 230 V. The device trips quickly on voltage anomalies and automatically restores supply when voltage returns to the normal range. Compact DIN-rail design, LED indicators for power and protection status, and a manual reset make it suitable for installation in domestic distribution boards and other distribution lines requiring protection.
Advantages
The unit offers automatic self-recovery after overvoltage or undervoltage events, combined earth-leakage and overcurrent protection, and fast response time of 1 s or less. Its compact dimensions and standard 35 mm DIN-rail mounting simplify installation. Built-in LED indicators show power and protection status, and the device is rated for electrical life exceeding 50,000 operations.
Suitable for
Household distribution boards and consumer units
Small commercial or light industrial three-phase systems with neutral
Protection of circuits and equipment subject to voltage fluctuations

How to use
Mount the device on a standard 35 mm DIN rail inside the distribution board with the mounting surface inclination not exceeding 5°. Connect the three phase conductors and neutral according to the wiring diagram and local electrical codes, and ensure the supply and load terminals are tightened to the specified torque. After wiring, switch on the supply; the device will monitor voltage and trip automatically on overvoltage or undervoltage conditions. When voltage returns to within the specified recovery thresholds, the protector will automatically reconnect the circuit. Observe the LED indicators to check power and protection status and perform manual reset or maintenance only after isolating the circuit.
Usage recommendations
Install and commission this protective device by a qualified electrician. Verify compatibility with the installation’s nominal voltage and load currents, and follow applicable national wiring regulations. Do not install with a mounting angle greater than 5°. Periodically inspect connections and indicator status as part of routine maintenance.
