A finalidade definida do contator elétrico da C.A. de Pólo da proteção 3 do motor com UL alistou
Electrical Motor Protection 3 Pole AC Contactor Definite Purpose with UL listed A Ccontactor is an electrically controlled switch used for switching a power circuit, similar to a relay except with higher current ratings, which is controlled by a circuit which has a much lower power level than the switched circuit. Description: UKC1 series AC Contactor is suitable for using in the circuits up to the rated voltage 660V AC50Hz or 60Hz, rated current up to 630A, for making,
Transformador atual 40mm da seqüência ZCT40 zero para o relé do escapamento da terra
ZCT40 Zero Sequence Current Transformer 40mm for Earth Leakage Relay Description: A zero-phase current transformer for use as a leakage current detecting element in a leakage current interrupter in which two magnetic materials of different permeability are provided so as to eliminate a range where the leakage current interrupter is inoperable without lowering its ability to distinguish noise components. The different magnetic materials may be provided as a single core
Contator de poder magnético de anti choque elétrico de 9A~85A 3P para a cor da proteção de circuito DC/AC do motor opcional
9A~85A 3P anti- electric shock Magnetic Power Contactor For Motor Circuit Protection DC/AC Color optional Description: GMC1 series magnetic AC contactor is suitable for using in the circuits up to rated voltage 660V AC 50/60HZ, rated current up to 800A, for making, breaking, frequently starting & controlling the AC motor and it can be combined with the auxiliary contacts, mechanical interlocking unit, switchover capacitor and etc. With the thermal relay, it is combined into
Proteção mecânica da sobrecarga do motor do bloqueio do contator industrial da C.A. 800A
Industrial 800A AC Contactor Mechanical Interlock Motor Overload Protection Description: UKC1 series ac contactor of mechanical chain contacts (hereinafter referred to as mechanical interlock unit) is based on the installation of machinery assembled chain body. It applies to AC 50 or 60Hz, rated voltage up to 660V and below, rated current up to 95A and the following circuit, for long-distance direct control of three-phase squirrel-cage motor starting, stopping and reversing
Contator do compressor da C.A. de Enclsoure do Fogo-retardador e relés trifásicos 180A
Three Phase Fire-retardant Enclsoure AC Compressor Contactor And Relays 180A Description: AC Contactors (Magnetic Contactor) provide remote control of primarily electric motors and compensation & heating systems by cable. They protect the instruments and equipments against overload currents by using thermal relays, for capacitor switching contactor. While switching on a capacitive circuit, a high frequency and large transient current peaks are produced. Switching of capacitor
Tipo magnético incluido proteção geral da tecla do contator da C.A. do interruptor do acionador de partida de motor
Enclosed type Magnetic Motor Starter Switch AC Contactor UKW1-22MB 22A push button type IP56 general protection A magnetic starter is a device designed to provide power to electric motors. It includes a contactor as an essential component, while also providing power-cutoff, under-voltage, and overload protection. Description: UKW1 series magnetic motor starter are suitable for 50Hz or 60Hz, rated voltage up to 660V, current up to 95A circuit. In order to protect motor
Contator 125A 150A da C.A. de Pólo dos contatores 4 do condicionamento de ar da economia de poder
Power saving Air Conditioning Contactors 4 Pole AC Contactor 125A 150A Description: Magnetic AC Contactor should have the high current value without being exposed to and damaged or boiling. This belongs to the quality of contactor. (Contact surface quality and weld technology) Especially at AC-3 and capacitor command, selectivity of contactor is very important. Current which passes through the contacts causes warming when the contactor is closed. This warming is limited with
