Description

Delixi CDLE6 Residual Current Circuit Breaker

Integrated 3P+N electronic residual current protection with digital display and RS485 communication.

Product Overview

The Delixi CDLE6 residual current operated circuit breaker provides electronic protection for three-phase four-wire TT distribution networks operating at AC 400 V and 50 Hz. Available in 100 A to 800 A frame sizes, it features an electronic release with adjustable overload, short-time short circuit, and instantaneous protection settings. The breaker incorporates Type AC residual current protection with 20 to 60 s automatic reclosing for delayed versions, a digital display for real-time monitoring, and external RS485 communication supporting DL/T 645 or Modbus protocols.

Technical FAQ & Selection Guide

💡 Frequently Asked Technical Questions & Selection Guide

Pure engineering specifications, tripping curve parameters, and electrical selection guidance for panel builders and system designers.

Curve Selection

How to choose between Tripping Curves B, C, and D for this miniature circuit breaker?

Curve B trips at 3–5 In (designed for resistive loads, electric heating, and domestic appliances with negligible inrush). Curve C trips at 5–10 In (the standard international choice for residential and commercial lighting, socket outlets, and small induction motors). Curve D trips at 10–14 In (specifically engineered for high-inrush inductive equipment such as industrial transformers, heavy motors, compressors, and welding circuits).

Breaking Capacity

How do I determine whether 6kA or 10kA breaking capacity is required for my installation?

Breaking capacity (Icn/Icu) must exceed the calculated prospective short-circuit fault current at the installation point. 6kA (IEC 60898-1) is standard for residential consumer units and sub-distribution branch circuits located downstream. 10kA (IEC 60947-2) is required for industrial facilities, main switchboards, commercial distribution panels, or circuits situated close to supply transformers where fault levels are high.

Poles & Neutral Isolation

How to choose the correct number of poles (1P, 1P+N, 2P, 3P, 3P+N, 4P) for single-phase and three-phase circuits?

For single-phase 230V circuits: 1P provides active phase protection; 1P+N or 2P isolates both live and neutral lines simultaneously (essential for TT earthing systems and sensitive sub-panels). For three-phase 400V systems: 3P protects balanced 3-wire motor loads; 3P+N or 4P is required for 4-wire mixed single-phase loads to ensure complete neutral disconnection during isolation.

DC vs AC Application

Can this circuit breaker be used in DC circuits (Solar PV, Battery Storage, Telecom)?

Standard AC breakers cannot safely extinguish DC arcs due to the absence of natural zero-crossing current. For DC circuits (60V to 1000V DC), select specialized DC breakers (such as DZ158-125 DC or NM8NDC series) equipped with permanent magnetic arc-blowout chutes and strictly observe polarity wiring to prevent arc re-ignition.

Modular Accessories & Interlocks

What modular accessories and mechanical interlocks can be fitted to this breaker?

Standard modular clip-on accessories can be mounted directly on the side without tools: OF (Auxiliary Contact for remote status indication), SD (Alarm Contact for trip fault signaling), MX (Shunt Trip for remote emergency tripping), MN (Under-voltage Release for voltage loss protection), and NXBZ mechanical interlock kits for manual generator/mains transfer switches.
