Description

 C65N MCB Mini circuit breaker

   

Application

C65N MCB is an all new high performance current limiting device with the ability to disconnect short circuits of up to 10kA. It is the newest model in 21st century. C65N MCB has many merits of high protective grade(up to lp20),high breaking capacity, good reliability of sensitive action, convenient multi-pole assorting, long using life etc. They are mainly used for overload and short circuit protection within the circuit of AC 50Hz,230V in single pole,400V in double, three and four poles. Meanwhile, they are also used in turning on and the electric apparatus and lighting circuit under the normal condition.

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?

A

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?

A

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?

A

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)?

A

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?

A

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.
