<p>The RCCB (Residual Current Circuit Breaker) is an essential device for industrial and commercial electrical systems, designed to protect against earth fault currents. With a rated current of 40 A, it efficiently handles moderate load requirements while ensuring safety and reliability.</p><p>This RCCB operates at a rated voltage of 230/400 VAC, making it suitable for diverse applications. It boasts a rated impulse withstand voltage of 4 kV and a rated insulation voltage of 500 V, providing robust protection against electrical surges and insulation failures.</p><p>Featuring four poles, this RCCB offers comprehensive coverage for multi-phase installations. Its power loss is minimal at just 3.2 W, contributing to energy efficiency in your system setup. The degree of protection varies with installation: IP20 when installed in an enclosure and IP40 when mounted as specified.</p><p>Installation is straightforward with the screw clamp terminal type, which supports secure connections. The recommended tightening torque is 2.8 N-m to ensure optimal contact without over-tightening. This device accommodates various cable cross-sections: from multi-wired cables up to 25 sq-mm to solid-core wires within the same range.</p><p>The RCCB&#39;s dimensions are compact yet substantial enough for effective performance—measuring 70 mm in width, 85 mm in height, and 69 mm in depth—while weighing only 375 g for easy handling during installation on DIN rails.</p><p>Designed for durability under typical operating conditions, this RCCB can endure up to 1000 electrical cycles. It functions effectively across standard frequencies of both 50 Hz and 60 Hz.</p><p>Safety features include a residual current type F classification and instantaneous operating characteristics that provide rapid response to faults. The device can handle short circuit currents up to 10 kA—a critical feature for safeguarding connected equipment from unexpected surges or faults.</p><p>For ease of integration into existing setups or new installations, the power supply connection is arbitrary—allowing flexibility in design configurations—and the wire stripping length required is just 12 mm.</p><p>Suitable ambient temperatures range from -25&#176;C to +55&#176;C, catering well to most indoor environments found across Australia’s varied climates. Additionally, it supports connecting capacities through busbar (10 sq-mm), rigid (25-25 sq-mm), or flexible wiring options (25-25 sq-mm).</p><p>Engineered with practicality in mind, this RCCB provides reliable performance without compromising on safety standards—a sound choice for those seeking dependable circuit protection solutions within their industrial or commercial infrastructure.</p>
