<p>When it comes to selecting reliable circuit protection devices for industrial and commercial applications, understanding the technical specifications is crucial. The product in question offers a robust solution with its well-rounded features designed for efficiency and safety.</p><p>Rated at 20 A, this device can handle moderate electrical loads, making it suitable for various applications. It operates efficiently within a rated voltage of 400 VAC and boasts a rated insulation voltage of 440 V, ensuring safe operation under normal conditions. Its capability to withstand impulse voltages up to 4 kV adds an extra layer of security against transient overvoltages.</p><p>One of the key aspects of this product is its breaking capacity of 11.3 kA, which indicates its ability to safely interrupt fault currents without damage. This feature aligns with industry standards IEC/EN 60898-1 and IEC/EN 60947-2, confirming its reliability in both residential and industrial settings.</p><p>The device&#39;s short circuit capacity stands at 10 kA, providing additional assurance that it will perform effectively during unexpected high current events. With an electrical durability rating of up to 20,000 cycles, users can expect long-term performance with minimal maintenance requirements.</p><p>Designed with practicality in mind, the product includes a screw clamp terminal type requiring a tightening torque of 2.8 N-m for secure connections. The compact dimensions—35 mm in width, 88 mm in height, and 69 mm in depth—make it easy to integrate into existing systems using standard DIN rail mounting.</p><p>Protection from environmental factors is ensured by its IP20 degree of protection and IP3 degree of pollution ratings. These classifications mean it&#39;s protected against solid objects over 12 mm but isn&#39;t waterproof; hence care should be taken regarding exposure to moisture or dust-heavy environments.</p><p>This device operates reliably across ambient temperatures ranging from -25&#176;C to +55&#176;C while being able to be stored safely between -40&#176;C and +70&#176;C. Its housing color RAL 7035 Grey provides a neutral aesthetic that blends seamlessly into most installations.</p><p>The curve type C characteristic allows the breaker to trip quickly under short-circuit conditions while still accommodating higher temporary overloads typical in motor start-ups or lighting circuits operating at frequencies between 50/60 Hz.</p><p>In summary, this circuit breaker combines durability with flexibility suitable for diverse operational environments where dependability cannot be compromised.</p>
