DZ47LE-63 ELCB 6A-63A 400V

Name: DZ47LE-63 ELCB
Brand: Hantu Electric

Product Overview

What This Model Does

The DZ47LE-63 ELCB is a residual current device for AC 50Hz/60Hz systems with rated voltages of 230V (1P+N, 2P) or 400V (3P, 3P+N, 4P), covering rated currents from 6A to 63A. It provides overload and short-circuit protection alongside residual current detection, suitable for infrequent switching of lines and motors. Built to IEC61009, it detects leakage currents down to 0.03A and trips within 0.1 seconds at 5 times the rated residual current. For panel builders and installers, it offers a compact, DIN rail-mounted solution that combines overcurrent and earth leakage protection in one device.

Key Benefits

Combines overcurrent and residual current protection in a single DIN rail device
Trip time under 0.1 seconds at 5×In for fast fault clearance
Available in 1P+N, 2P, 3P, 3P+N, and 4P configurations for flexible circuit design
Supports multiple residual current thresholds including 0.03A, 0.05A, 0.1A, and 0.3A
Rated short-circuit breaking capacity of 6kA for 6–32A and 4.5kA for 40–63A
Suitable for both residential and light industrial applications with stable performance

Who It Is For

Electrical wholesalers stocking combined protection devices
Panel builders integrating ELCB into distribution boards
Switchgear assemblers building custom control cabinets
Solar EPC contractors installing protection in PV systems
OEM/ODM buyers requiring a compliant residual current device for branded panels

Problems It Solves

A separate MCB and RCD must be installed to meet protection requirements, increasing panel space and cost
Faults due to earth leakage go undetected without a dedicated residual current device
Manual switching of motors or circuits requires additional contactors or switches
Lack of fast trip response at high fault currents increases risk of fire or equipment damage
Inconsistent protection levels across different circuits due to mismatched device types

Application Scenarios

Residential distribution boards where both overload and earth leakage protection are required
Light commercial installations with single-phase or three-phase circuits needing combined protection
Motor control circuits with infrequent start and stop operations
Industrial control panels where space is limited and dual protection is needed
Renewable energy systems such as solar inverters with 230V/400V AC outputs

Comparison

How It Compares

Separate MCB and RCD	Reduces panel space and wiring complexity, though with higher unit cost
RCBO	Same protection function but with fixed trip current, while RCBO allows more configuration options
Conventional ELCB with separate overcurrent protection	Combines both functions in one device, reducing installation time and part count
4P RCBO	DZ47LE-63 offers lower cost and simpler design for applications not requiring full RCBO functionality

Use Guide

Connect the line and neutral conductors to the appropriate terminals based on pole count
Ensure the rated current matches the circuit load and wire size
Test the device after installation by pressing the test button to verify trip function
Do not operate if the device shows signs of damage or overheating
Keep the manual test button accessible for periodic functional checks
