Features

5 .1 The product mainly consists of three-ph ase pole, spring operating mechanism, drive system, conductingloop, control unit and housing (made of ordinary carbon steel spray or stainless steel). The overallstructure is of the three-phase pole type with miniaturization design, full-closed structure and good sealingproperty, especially suitable for cold and wet areas:
5 .2 The eticient and reliable spring operating mechanism (manual or electric, with manual finctions or neardistance rem ote control for the electric type), featuring with low-power energy-storage motor and lowopening and closing energy consumption. The operating mechanism is sealed in the box to effectivelyprevent rust to parts, guaranteeing the reliable action of mechanismm;5.3 The pole is m ade of imported epoxy resin and coated with silicone rubber featuring with high temperaturelow temperature, ultraviolet ray and aging resistance;5 .4 An external two-phase or three-phase protective curent transformer is provided to realize overcurrentprotection and fault current quick-break protection together with inrush current, and the protection delaytime can be adjustable,
5.5 The interphase protection CT and zero-sequence C'T integrated structure can be configured to realizeparaeter setting, single-phase grounding protection, three-section protection, reclosing, and faultaccident mem ory together with the intelligent controller (the extemmal power supply PT is used to supplythe operating power); the controller has the corresponding communication module with data uploading tomaster station, fault feedback and “four-remote" functions to form an intelligent circuit breaker achievingdistribution network autom ation;
5.6 The circuit breaker can be equipped with an isolating knife switch (at single or dual sides) with three.phase linkage to form an obvious isolating distance at the incoming (outgoing) side, a reliable mechanicalanti-misoperation interlock is provided between the main switch and the isolating switch to guarantee safeand reliable operation.
