<p>The RCCB (Residual Current Circuit Breaker) presented here is a robust solution designed for industrial and commercial applications, offering reliable protection against electrical faults. With a rated current of 100 A, this device efficiently safeguards circuits by detecting residual currents and disconnecting the circuit to prevent potential hazards such as electric shocks or fire.</p><p>This RCCB is engineered to handle a rated voltage of 230/400 VAC and operates effectively within a frequency range of 50/60 Hz, making it suitable for various electrical systems. The unit boasts an impressive rated impulse withstand voltage of 4 kV and an insulation voltage of 500 V, ensuring high resilience against transient over-voltages.</p><p>Designed with practicality in mind, the RCCB features four poles and utilizes screw clamp terminals that facilitate secure connections. The tightening torque stands at 2.8 N-m, providing adequate clamping force for stable performance. It accommodates multiple wire types with a cable cross-section capacity ranging from 0-35 sq-mm for multi-wired cables to 35 sq-mm for solid-core wires.</p><p>The device&#39;s compact dimensions—70 mm in width, 85 mm in height, and 69 mm in depth—allow seamless integration into existing setups while occupying minimal space on the DIN rail mount. Despite its compact size, it maintains durability with an electrical endurance rating of up to 1000 cycles.</p><p>Environmental adaptability is another strength; the RCCB operates reliably across ambient temperatures from -25&#176;C to +55&#176;C. Its degree of protection varies between IP20/IP40 depending on installation conditions, safeguarding internal components from dust ingress and accidental contact.</p><p>In terms of safety features, this Type A RCCB supports instantaneous operating characteristics with a rated short circuit current capacity up to 10 kA. This ensures immediate response during fault conditions without delay. Additionally, it offers flexible power supply connections and can be connected arbitrarily without compromising functionality.</p><p>Installation is straightforward thanks to specified wire stripping lengths—12.7 mm at the top terminal and 14.9 mm at the bottom—and compatibility with busbars up to 10 sq-mm as well as rigid or flexible conductors up to 35 sq-mm.</p><p>Overall weighing just around 380 g yet delivering substantial protective capabilities alongside low power loss (8.2 W), this RCCB represents an efficient choice balancing performance with energy conservation—a crucial consideration when evaluating long-term operational costs within any facility&#39;s infrastructure management strategy.</p>
