<p>The RCCB, or Residual Current Circuit Breaker, is a robust and reliable component designed for industrial and commercial applications. With a rated current of 25 A, it provides essential protection by detecting and interrupting fault currents to prevent electrical hazards.</p><p>This model operates efficiently at both 50 and 60 Hz frequencies, making it versatile for various setups. It boasts a rated impulse withstand voltage of 4 kV and an insulation voltage of 500 V, ensuring it can handle unexpected surges without compromising safety.</p><p>Constructed with two poles, this RCCB offers flexibility in installation with its screw clamp terminal type. The tightening torque is set at 2.8 N-m to ensure secure connections. Its dimensions are compact with a width of 35 mm, height of 85 mm, and depth of 69 mm—ideal for space-constrained environments on DIN rails.</p><p>In terms of durability, the RCCB is designed to endure up to 1000 electrical cycles, reflecting its longevity in demanding conditions. It supports cable cross sections ranging from multi-wired configurations (0-25 sq-mm) to solid-core wires (25-25 sq-mm), accommodating different wiring needs.</p><p>The device&#39;s power loss is minimal at just 1 W, contributing to energy efficiency in systems where it&#39;s deployed. Rated for short circuit currents up to 10 kA, this RCCB ensures resilience against high fault currents.</p><p>Its degree of protection varies between IP20/IP40 depending on installation specifics—offering sufficient protection against dust ingress—and has an operational temperature range from -25&#176;C to +55&#176;C suited for diverse environmental conditions.</p><p>Mounting is straightforward via standard DIN rail systems while allowing arbitrary power supply connections which enhance installation flexibility. The wire stripping length required is a precise 12 mm which aids in maintaining consistent connectivity standards.</p><p>Designed as Type A residual current device, this model responds effectively to alternating and pulsating direct residual currents—a critical feature in modern electrical installations where mixed loads are common. The operating characteristic being instantaneous ensures rapid response during fault conditions enhancing overall system safety.</p><p>For connection capacity requirements: busbar connections support up to 10 sq-mm while rigid and flexible connections accommodate up to 25 sq-mm each—catering well across varied panel designs.</p><p>Overall weighing only about 200 g makes handling manageable during installation or maintenance tasks without compromising structural integrity or performance reliability within your setup&#39;s parameters.</p>
