Family Overview
Selection And Application Context
Our selection of Residual Current Circuit Breakers (RCCBs) offers robust protection for a wide array of electrical applications. Engineered to comply with IEC61008-1 and IEC62423 standards, these devices are essential components in ensuring the safety of personnel and property.
RCCBs operate by detecting even small imbalances between the current flowing into and out of a circuit. Such imbalances typically occur when current leaks to earth, often through a person or faulty insulation. Upon detecting a residual current exceeding a predetermined threshold, such as 30mA, 100mA, or 300mA, the RCCB rapidly disconnects the power supply, preventing severe injury or damage.
We offer various RCCB types to suit specific requirements, including AC, A, S, G, and B types, each designed for different waveform characteristics of residual current. Our models are available in both electromagnetic and electronic configurations, ensuring compatibility with diverse system designs. They are rated for voltages from 240V to 415V and frequencies of 50Hz to 60Hz, making them suitable for many global markets. With a robust electrical and mechanical life of 10,000 cycles, these DIN-rail mountable devices provide long-term reliability. We also support ODM and private label manufacturing for partners seeking tailored solutions.
Integrating our RCCBs into your electrical distribution panels enhances overall safety and compliance, providing peace of mind for residential, commercial, and industrial environments.

FAQ
Frequently Asked Questions
What is a Residual Current Circuit Breaker (RCCB)?
An RCCB is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the live and neutral conductors, indicating...
What is the difference between Type AC and Type A RCCBs?
Type AC RCCBs are designed to detect sinusoidal AC residual currents. Type A RCCBs can detect both sinusoidal AC residual currents and pulsating DC residual currents, offering broader...
How do I choose the correct rated residual operating current for an RCCB?
The choice depends on the application. For personal protection against direct contact, 30mA is typically used. Higher values like 100mA or 300mA are often used for fire protection...
Can RCCBs protect against overcurrents or short circuits?
No, RCCBs are specifically designed to protect against earth leakage currents. They do not provide protection against overcurrents or short circuits. For these protections, Miniature Circuit Breakers (MCBs)...
Are your RCCBs suitable for DIN-rail mounting?
Yes, all our Residual Current Circuit Breakers are designed for standard DIN-rail mounting, ensuring straightforward installation into existing or new distribution boards and enclosures.
