Protect circuits By current range By application

Our range of RCBO circuit breakers is designed to deliver integrated protection for a wide array of electrical installations. Combining the capabilities of overcurrent protection (against both overloads and short circuits) and residual current protection (earth leakage), these devices ensure enhanced safety for personnel and equipment. Manufactured to meet the IEC61009-1 standard, our RCBOs are suitable for rated voltages from 240V to 415V and operate efficiently across 50Hz to 60Hz frequencies.

We offer various RCBO types, including AC, A, and B, to address different application requirements for detecting residual currents. The tripping characteristics are precisely engineered with B, C, and D curves to match specific load types and fault conditions. For instance, B-curve RCBOs trip at (3-5)xIn, C-curve at (5-10)xIn, and D-curve at (10-20)xIn, providing flexibility for diverse circuit designs.

These compact devices feature DIN-rail mounting for straightforward installation in distribution boards, making them an efficient choice for space-limited environments. With an IP20 degree of protection, they are suitable for general indoor electrical enclosures. Our RCBOs are built for durability, boasting an electrical and mechanical life of 20,000 cycles, ensuring long-term performance and reliability.

Available with rated residual operating currents of 30mA, 100mA, and 300mA, our RCBOs can be selected to meet specific sensitivity requirements for different protective zones. We support ODM and private label manufacturing, providing tailored solutions for OEM panel builders and electrical contractors seeking high-quality, compliant circuit protection devices. Our commitment is to supply robust and effective RCBOs that contribute to safer and more reliable electrical systems.
