Delixi CDM3-63 C16 2P CDM3 series Moulded Case Circuit Breaker

Let's take a detailed look at the Delixi CDM3-63 C16 2P miniature circuit breaker.

This is a basic circuit breaker widely used in residential and commercial power distribution.

I. Overall Product Positioning

This is a two-pole miniature circuit breaker, part of the Delixi CDM3 series. It does not provide leakage protection; its core function is to provide overload and short-circuit protection for a complete circuit (including the live and neutral wires).

II. Model Details

The model CDM3-63 C16 2P can be broken down into the following components:

1. Series: CDM3

This indicates that it belongs to Delixi's CDM3 series. This series, known for its cost-effectiveness, stability, and reliability, has become one of Delixi's most popular and popular product lines, widely used in residential, commercial, and light industrial applications.

2. Frame Rating: -63

This refers to the maximum current rating of the frame or "frame" to which the circuit breaker belongs. Within the CDM3-63 framework, circuit breakers with various current ratings, ranging from 1A to 63A, can be manufactured. Your circuit breaker is rated for 16A, but it belongs to the 63A family.

3. Tripping Curve and Rated Current: C16

C: This is the tripping characteristic curve. The C curve is the most common type, with an instantaneous tripping current range of 5 to 10 times the rated current. It is suitable for circuits with small inductive loads but moderate inrush currents, such as lighting, sockets, and appliances. It is a standard choice for household and commercial power distribution.

16: This is the rated operating current, measured in amperes. This circuit breaker is designed to safely handle a current of 16A for extended periods. When the current in the circuit exceeds 16A continuously, the bimetallic strip inside the circuit breaker will overheat and bend, triggering a tripping mechanism after a delay, providing overload protection.

4. Number of Poles: 2P

2P stands for bipolar. This means it has two independent protection poles, capable of simultaneously connecting and disconnecting the live (L) and neutral (N) wires.

Compared to 1P circuit breakers, which only disconnect the live wire, 2P circuit breakers completely isolate the circuit when closed or tripped, providing increased safety.

They are typically two modules (36mm) wide and occupy the space of two 1P circuit breakers in the distribution box.
