<p>When selecting a reliable Residual Current Circuit Breaker (RCCB) for your industrial or commercial applications, understanding the technical specifications is crucial. This RCCB, designed to meet rigorous standards, offers robust protection and performance.</p><p>With a rated current of 100 A and a residual current type classified as Type A, this RCCB ensures effective detection and interruption of earth faults. Its rated voltage stands at 230 V with an insulation voltage of 500 V, providing ample safety margins for diverse electrical environments. The unit boasts a rated impulse withstand voltage of 4 kV, ensuring resilience against transient overvoltages typically caused by lightning strikes or switching operations.</p><p>The RCCB&#39;s physical dimensions include a width of 35 mm, height of 85 mm, and depth of 69 mm—compact enough for efficient space utilization on DIN rail systems. It weighs in at just 200 g, making it light yet sturdy. Its degree of protection varies between IP20/IP40 depending on installation conditions, offering adequate shielding from dust ingress and accidental contact.</p><p>Designed with user-friendly screw clamp terminals that require a tightening torque of 2.8 N-m, this device accommodates cable cross-sections ranging from multi-wired configurations (0-35 sq-mm) to solid-core connections (35-35 sq-mm). The wire stripping length is specified at 12.7 mm for the top terminal and 14.9 mm for the bottom terminal to ensure optimal connection integrity.</p><p>This RCCB operates efficiently across standard power frequencies (50/60 Hz) with an electrical durability rating reaching up to 1000 cycles—a testament to its longevity under normal use conditions. It also supports arbitrary power supply connections and maintains operational stability within ambient temperatures from -25&#176;C to +55&#176;C.</p><p>For those concerned about short circuit scenarios, this model has been tested up to a rated short circuit current capacity of 10 kA. In terms of connecting capacity: busbar support is available up to 10 sq-mm; rigid cables can be connected in the range between two sets each accommodating up to 35 sq-mm; flexible cables are similarly supported within these parameters.</p><p>Finally, the RCCB features instantaneous operating characteristics which are essential for minimizing response time during fault conditions—ensuring swift isolation when necessary without delay.</p><p>This combination of features makes it an ideal choice where reliability under demanding conditions is non-negotiable while still maintaining ease-of-installation through its straightforward mounting type on standard DIN rails.</p>
