Contactor 40A

Contactors TERMOCASA have contacts (contact pad) with a concentration of 99% Silver

• The main elements that make up any contactor are the coil and the contacts (contact pad).
• The coil is an element that does not differ much from one manufacturer to another.
• The contacts (contact pad) are the elements that differ greatly from one manufacturer to another, they have a different concentration of silver (superconductor) or most have no silver at all. The lower the silver concentration in the contact, the greater the risk of oxidation of the contacts and blackening due to arcing, which can lead to open circuits and failure of three-phase motors or other devices sensitive to voltage interruptions or fluctuations.

Range of protections and brand order TERMOCASA it is designed by engineers Termocasa, automation experts, and produced to provide innovative and reliable solutions for your installations and equipment. Whatever difficulty you may encounter, we are at your disposal with varied and suitable products both financially and qualitatively. In this sense, we present the 1+3P ND contactor model that operates with a nominal current of 40A, at a nominal frequency of 50-60Hz.
