Earth Leakage add-on Blocks are essential protective devices to ensure the safety of electrical installations by detecting and automatically interrupting the power supply in the event of current leakage to earth. These devices are designed to constantly monitor the balance between the current entering and leaving a circuit. If there is a difference, even a small one, the Earth Leakage add-on Blocks promptly intervenes to prevent electric shocks or potential fires.
 

Earth Leakage add-on Blocks Catalogue
 

In this category, you will find a selection of the best earth leakage add-on blocks produced by leading brands such as ABB, Bticino and Siemens, synonymous with reliability and quality in the electrical sector. These devices are available in different configurations, allowing a wide choice according to the specific needs of the installation. The earth leakage add-on blocks vary in current capacity, with models ranging from 25 up to 250 amperes, to suit different types of circuits, from the smallest domestic installations to the most complex industrial ones. The variety of modules, from the most compact to the largest, allows flexible installation in different switchboards. In addition, the availability of single and multi-pole versions (such as 1P+N, 2P, 3P, 4P) makes it possible to choose the most suitable device for the type of circuit to be protected. A fundamental aspect is the type of differential, which can vary between types A, AC, AS, B and F, each designed to detect specific types of faults, from direct to pulsating or mixed currents. This guarantees customised protection depending on load characteristics and operating conditions.
In addition, the earth leakage add-on blocks support different operating voltages, such as 230VAC, 400VAC and up to 690VAC, for extended compatibility with various electrical systems. The sensitivity of the devices, expressed in differential amperes (from 0.03A up to 1A), is another key feature that allows the most suitable protection to be selected according to the specific safety requirements of the system. Thanks to these characteristics, the earth leakage add-on blocks in this section are ideal for guaranteeing maximum safety and reliability, offering complete protection against electrical hazards, with the excellence and innovation that only the leading brands in the sector can guarantee.
