Three-phase Four-wire Energy measuring terminal bl

HS6/SJ1 Type energy measuring terminal block General: HS6/SJ1 Type energy measuring terminal blocks are developed on the basis of former ones according to the suggestion from relevant experts of national electric power bureau.This provides a favorable environment for adopting standard wiring. This products is specially applied for standard wiring of energy measuring equipment,It is also suitable for secondary circuit of rated voltage up to 660V and rated current up to 20A.It is used to change or inspect the electric equipment such as energy meter.electric instrument and relaying protection equipment under on-load circumstance,It guarantees operater personal safety and improves fieldwork effiency.It plays a positive role in improving the measuring correctness.The products can always receive favorable comments in the power system field. Structural features: HS6/SJ1 Type energy measuring terminal blocks have excellent quality.It adopts high-molecular polycarbonate material imported from America.It has advantages of bright and elegant appearance,high impact resistance,moisture resistance,favorable insulation;ageing resistance;flame retardant and high temperature resistant.It can work at -40°C +120°C for long term.The screw adopts compound recess,which is suitable for flathead screw driver and crossed screw driver,The voltage circuit adopts one inlet three outlet,All phases are marked with phase sequence,which is not only convenient for combined wiring,but also can avoid measuring error caused by wiring wrong phase sequence.The terminal block cover is fixed with two sealing screws,which is helpful to provent electricity-theft.
