Consider another protection device from Eaton. Today we are reviewing the xPole Home HNC-25/2/003 residual current circuit breaker or in the usual words RCD. The purpose of the device is to react to earth leakage currents, instantly disconnecting the problem area where the insulation was damaged, or a person's touch to the damaged area. In this article, we have provided a description of the characteristics, appearance, and connection diagram of a residual current device from Eaton.

Appearance
The two-pole RCD xPole Home HNC-25/2/003 is made of dense, smooth white plastic. On the front side there is a closing lever and a TEST button, under it is a window of the trip unit status indicator. For connection to the conductors, there are screw terminals, two at the top (1, N) and two at the bottom (2, N). You can connect a wire with a cross section of up to 35 mm sq. To them.
Also, on the front of the case on the front panel, general information about the RCD is given. xPole Home H - series, NC - residual current circuit breaker, 25 - rated current of the device, 2 - number of poles, 003 - 0.03 mA rated current of the residual current release.
Specifications
The main characteristics of RCD Eaton xPole Home HNC-25/2/003 we have provided below:
- Rated voltage and frequency of alternating current: 230/400 V, 50 Hz.
- Rated operating current 30 mA.
- TEST button voltage range: 196 to 264 V.
- Breaking capacity: 6 kA.
- Permissible operating temperature: -25 ° C to + 40 ° C.
- Protection degree IP40.
- Service life: 4 thousand. cycles for electrical components and 20 thous. cycles to mechanical.
It is important to note that this line of residual current devices is manufactured with a nominal current from 25 to 63A, which allows you to choose a suitable rating, depending on the installed machines in dashboard.
Connection diagram
On the right side there is a sticker from the manufacturer with a wiring diagram and information. Installation of the residual current device is carried out on a standard DIN rail. According to the manufacturer's data, xPole Home HNC-25/2/003 can be connected to both the upper and lower terminals. The location of the device is not critical to the position in space.
Also, according to the manufacturer's instructions, the residual current circuit breaker has a functional independence from the supply voltage. Installation of RCD allows you to modernize existing networks by installing them in power supply systems, making them fireproof and eliminating electrical injuries.
Important: residual current switches do not respond to short-circuit currents or objects hit between phase and zero. Also, the RCD will not protect the wiring from overload!
The figure below provides a connection diagram for a group of machines and RCDs:
In order to make sure that the device is working properly, it is necessary to check the circuit breaker at least once every six months by pressing the TEST button. In dusty or high humidity conditions, the check should be carried out at least once a month.
