Guide to understand and correctly use electrical protection devices<\/strong><\/p>\n

What is a magnetotherm?<\/span><\/h4>\n

A thermomagnetic switch is a protection device designed to automatically open electrical circuits when overloads occur, whether it be overloads or short circuits. Its main function is to protect both the electrical installation and its receivers.<\/p>\n

ANATOMY OF A MAGNETOTHERMIC<\/span><\/h4>\n

\u00b7 MANUFACTURER'S NAME; <\/strong>identifies the manufacturer that designed, tested, and guarantees the performance of the product.<\/p>\n

\u00b7 MODEL; <\/strong>It allows identifying the specific technical characteristics of the model through the catalog.<\/p>\n

\u00b7 NOMINAL OPERATIONAL STRESS (EU); <\/strong>Usable tension for which it has been designed<\/p>\n

\u00b7 COURTSHIP POWER; <\/strong>Maximum short-circuit current that can be safely interrupted<\/p>\n

\u00b7 SHOT CURVE (B,C,D); <\/strong>Graph showing the firing time of the magnetotermic device as a function of the intensity that passes through it. NOMINAL CURRENT (In); <\/strong>Maximum current that the magnetotermic can withstand continuously without sparking (at a reference temperature)<\/p>\n

\u00b7 VISUAL STATE INDICATOR (ON<\/span> U OFF<\/span>)<\/strong><\/p>\n

\u00b7 OPERATIONAL SYMBOL; <\/strong>illustrates the working mechanism. It is a visual representation<\/p>\n

\u00b7 COMPLIANCE REGULATIONS; <\/strong>Verifies that it complies with international product standards regarding construction and performance testing. IEC 60898-1 (Residential Use) IEC 60947-2 (Industrial Use)<\/p>\n

Which curve to choose?<\/span><\/h4>\n

The choice of the switch curve depends on the type of load and the protection needs. For example, some types of loads generate high starting currents, which could cause unwanted spikes if the correct curve is not selected\u2026<\/p>\n
