For professionals in the electrical engineering and automation sectors, selecting the right Residual Current Circuit Breaker (RCCB) is crucial for ensuring safety and reliability. This RCCB offers a comprehensive solution with its robust specifications tailored for industrial and commercial applications.
The unit boasts a rated current of 25 A, making it suitable for various load requirements. It operates efficiently under both 230 VAC and 400 VAC systems, providing flexibility across different installations. With a rated impulse withstand voltage of 4 kV and an insulation voltage of 500 V, this RCCB ensures high resilience against overvoltages.
Safety is further enhanced by its breaking capacity of 30 mA, designed to provide effective protection against earth faults. The device also features dual degrees of protection: IP20/IP40, safeguarding internal components from dust ingress at different installation environments.
Designed with practicality in mind, this RCCB incorporates a screw clamp terminal type that supports easy installation and secure connections. The tightening torque is specified at 2.8 N-m to guarantee optimal contact pressure without damaging conductors. Its versatility extends to accommodating cable cross sections ranging from multi-wired (0-25 sq-mm) to solid-core cables (25-25 sq-mm).
The RCCB's dimensions are compact yet substantial enough for stability: measuring 70 mm in width, 85 mm in height, and 69 mm in depth with a weight of just 360 g. This makes it an ideal choice for space-constrained panels while maintaining ease of handling during installation on standard DIN rails.
Operational reliability is underscored by its electrical durability rating of up to 1000 cycles—ensuring long-term performance even under frequent switching conditions—and an ambient temperature range from -25 to +55°C allows it to function effectively in diverse climatic conditions.
Additionally, the product's instantaneous operating characteristic provides rapid response times essential for minimizing potential hazards due to fault conditions. Rated short-circuit current stands at an impressive 10 kA which speaks volumes about its robustness under extreme scenarios.
Connecting capacity options include busbar connections up to 10 sq-mm as well as rigid or flexible cables between sizes of up to 25 sq-mm each—further enhancing adaptability across various setups while maintaining integrity through arbitrary power supply connections within test voltages spanning from170 V–254 V AC levels ensuring compatibility across numerous applications
Overall this RCCB presents itself not only as technically sound but also user-friendly thanks largely due consideration given towards installer needs such as wire stripping length set precisely at12mm allowing quick preparation before securing into place confidently knowing all aspects have been accounted including degree pollution rating classified under IP2 standards confirming suitability where environmental factors demand higher attention during selection processes ultimately leading better informed decisions based upon factual data rather than assumptions alone thereby achieving greater satisfaction post-installation experiences among discerning clientele seeking value-driven solutions aligned closely alongside specific project objectives Manufacturer Part Number: [Not Provided]
