Release Time: 2026-03-14

Рассмотрите разницу между Защита RCBO и RCCB прежде чем распределять функции перегрузки и остаточного тока.

Construction and protection are separate fields

Поле	What to confirm
Electromagnetic construction	Exact release and supply dependence
Residual-current type	AC/A/B or other declared waveform scope
Sensitivity	Required operating threshold
Категория продукции	RCCB or combined RCBO function
Fault arrangement	Coordinated overcurrent device and ratings

Verification	What it checks	Limitation
Front test button	Specified functional response	Not the whole installation
Suitable RCD tester	Required waveform and trip tests	Follow device and installation procedure
Wiring inspection	Neutral and sensing arrangement	Does not replace electrical tests
Document review	Exact model and scope	Not physical installation evidence

Руководство по защита от остаточного тока описывает условия установки, которые нельзя установить только на основании маркировки устройства.

Electromagnetic construction does not specify the waveform

An electromagnetic release describes operating construction, while Type AC, A or B describes residual-current response. Confirm both independently. A voltage-independent release claim also needs its own operating conditions; it does not prove automatic protection against every open-neutral condition.

An RCCB does not include overcurrent protection merely because it is electromagnetic. Specify the coordinated MCB or fuse, current rating and conditional short-circuit arrangement. Verify residual-current operation with equipment appropriate to the declared type and record the installation results.

Introduced the JC3RS, an advanced electromagnetic Residual Current Device (RCD) designed to strengthen electrical safety across a range of environments. With its reliable earth leakage protection, the device helps prevent electric shocks and fire hazards caused by fault currents. It’s a timely release, addressing growing safety concerns in both residential and commercial infrastructures.

What sets the JC3RS apart is its versatility. Suitable for consumer units and distribution boards, it can be installed in industrial facilities, commercial complexes, high-rise buildings, and even private homes. The RCD comes with a пропускная способность of up to 10kA and handles rated currents as high as 100A. Users can choose between Type A or AC models, with tripping sensitivities ranging from 30mA to 500mA—allowing for precise customization based on specific circuit requirements.

Installation flexibility is another highlight. The device supports connections from either the top or bottom, simplifying integration into existing electrical panels. Compliant with IEC 61008-1 and EN61008-1 standards, the JC3RS assures users of its reliability and adherence to international safety norms.

Available in 1P+N and 3P+N pole configurations, the product lineup covers ampere ratings from 25A to 100A. Whether for a small household or a large industrial setup, there’s a variant tailored to the need.

Industry experts note that electromagnetic RCDs like the JC3RS offer a higher level of durability and consistent performance compared to electronic types, especially in environments with voltage fluctuations. This makes them a prudent long-term investment for safety-conscious projects.

Now supporting orders and technical inquiries. The launch underscores the company’s focus on delivering practical, safety-enhancing solutions that cater to real-world electrical challenges. As regulations tighten and awareness grows, such innovations play a crucial role in protecting both people and property.

Часто задаваемые вопросы

Does electromagnetic mean Type B RCD?

No. Construction and waveform capability are separate characteristics. Read the exact residual-current type on the model documentation.

Does an electromagnetic RCCB protect against overload?

Not if it is an RCCB without integral защита от перегрузки. Provide a coordinated MCB or fuse as required.

Is every electromagnetic RCD independent of every supply fault?

No universal claim is justified. Confirm its declared supply dependence and behaviour under the specific fault condition.

What is needed besides the test button?

Complete the installation verification required by the applicable rules using a suitable tester. The button is a functional check, not the complete acceptance record.
