Type B Residual Current Device

B type residual current devices stand out as the most advanced Residual Current Devices. B type residual current devices, which can operate smoothly in high-frequency and high-risk installations, provide the most effective protection against directly occurring leakage currents. As Yılkomer, we carry out the national responsibility of the Italian GEWISS brand residual current devices, and within our product range including AC type, A type, A IR, F type and B type relays, our B type residual current devices offer the widest protection characteristics and non-nuisance tripping features.

• B type residual current devices are the most ideal products for both AC and DC applications.
• B type residual current devices are the only option for DC applications.
• B type residual current devices provide the most effective protection against series fault currents.
• With the Gewiss B type 90 IDP residual current device, the concept of nuisance tripping is eliminated.
• It does not trip up to 1 kHz at variable frequencies (AC type devices are limited to 50 Hz).

THE MOST IDEAL RESIDUAL CURRENT DEVICE FOR SOLAR POWER PLANTS IS THE B TYPE RCD.

Gewiss B class residual current devices are the most ideal solution for areas where DC fault currents may occur. They are ideal for solar panels, generators, and DC load rectifiers.

Additionally, B class residual current devices are widely used in;

• Electric vehicle charging stations
• DC converters
• Elevator applications
• High-risk equipment such as MRI devices in hospitals
• Uninterruptible Power Supplies (UPS)
• DC motors
• Rectifiers

THE MOST IDEAL PRODUCT TO ELIMINATE RESIDUAL CURRENT DEVICE PROBLEMS!

IF WE LOOK AT THE KEY ADVANTAGES OF THE GEWISS 90IDP B TYPE RESIDUAL CURRENT DEVICE;

Thanks to the LED on the front of the device, you can continuously monitor and check its status.

Provides protection against atmospheric current increases such as lightning and prevents nuisance tripping.

Resistant to harmonics, does not cause unnecessary tripping.

Can be integrated with restart motor systems. After a fault is cleared, it can automatically reconnect.

Our B type residual current device is the most ideal solution for all applications where A type residual current devices are insufficient.

A and AC type residual current devices, which are used in 99% of power electronics applications, cannot detect high-frequency DC and AC leakage currents. They are ineffective against harmonics and sudden voltage rises and cause nuisance tripping. Especially in industrial facilities, residual current devices are often disabled due to nuisance tripping, creating serious risks. The most effective protection against nuisance tripping in industrial facilities is provided by B TYPE residual current devices.
