Ayyuka
Chance M3 Disconnect Switch na single-phase hookstick-operated switch. Ya kamata a kan yawan kammala a kan abincin jirgin sama a kan electrical distribution systems a kan 38kV. Variations a design suna iya amfani a kan ayyukan distribution switch ko substation switch.
Da rating ta 600 ko 900 amps continuous, 40,000 amps momentary, and 25,000 amps sym. 2-seconds short-time withstand, M3 zai iya amfani a:
● Dip/Riser poles ● Single crossarm ● Double crossarm ● Aluminum or steel structure
kuma har da ayyukan disconnect switch da za a iya amfani a kan line sectionalizing. Amfani da optional bypass studs ya taimaka wajen bypassing reclosers, regulators, capacitor banks ko metering devices.
Nau'in Yawa
Duk Chance M3 disconnect switches suna da Loadbreak hooks wadannan suna taimaka wajen blade closing guide and for use with a portable Loadbreak tool. Don bukatar switch a kan load, amfani da an approved Loadbreak tool and refer to the tool manufacturer for instructions.
Positive latching ana bayar. Silver-plating on the contact areas enhances efficient current transfer. For easy opening and ice-breaking action, the pull ring activates the latch as a pry-out lever.
