<p>When it comes to ensuring the safety and reliability of your electrical systems, choosing the right circuit breaker is crucial. The PISA11 Electronic Circuit Breaker offers a robust solution suited for industrial and commercial applications. Designed with precision, this model caters to those who need dependable performance in demanding environments.</p><p>The PISA11 is engineered to handle a rated current of 4 A, making it suitable for various applications where moderate current protection is required. Its compact dimensions—45 mm in width, 75 mm in height, and 91 mm in depth—allow for efficient use of space on DIN rails, a common mounting type that facilitates easy integration into existing systems.</p><p>Safety and compliance are at the forefront with this circuit breaker. It meets multiple standards and approvals including ATEX EN 60079 for explosive atmospheres, Class I Div. 2 certifications from CSA for both Canada and the USA, as well as UL listings such as UL 508 (Canada &amp; USA) and UL 60950-1 (Canada &amp; USA). These certifications ensure that the PISA11 adheres to stringent safety requirements across different regions.</p><p>Operating within a voltage range of 24 VDC ensures compatibility with standard DC power systems while maintaining efficiency with minimal power loss at just 1 W. The degree of protection rated at IP20 safeguards against solid objects greater than 12mm but should be noted it&#39;s not waterproof or dustproof.</p><p>For those concerned about environmental conditions, this circuit breaker operates reliably within temperatures ranging from -25 to 70 degrees Celsius. This broad operational temperature range makes it versatile enough for use in both indoor installations and more challenging outdoor settings.</p><p>Key features include a drop voltage of just 41 mV which signifies minimal energy wastage during operation. Additionally, its output current limitation stands at an impressive 12.7 A providing ample headroom beyond its rated current without compromising safety.</p><p>The device&#39;s shutdown time is set at 110 ms ensuring rapid response during fault conditions while maintaining system integrity through controlled turn-on delays of outputs measured at approximately 270 ms—a critical feature when managing sensitive electronic loads.</p><p>Moreover, its voltage protection level is fixed at around 21 VDC offering substantial safeguard against overvoltage incidents thus prolonging equipment lifespan connected downstream from this unit.</p><p>With all these attributes packaged into one lightweight unit weighing only about120 g ,the PISA11 proves itself as not merely another component but rather an essential asset within any sophisticated electrical setup looking towards optimal functionality backed by comprehensive international standardization credentials .</p>
