ZW32-12-630
Adopting advanced vacuum arc extinction technology, this circuit breaker features reliable breaking capacity and excellent insulation performance. It supports arc-free, low-noise and pollution-free operation, adapting to frequent switching and long-term stable 630A full-load operation.
Equipped with a high-reliability spring operating mechanism, ZW32-12/630 operates flexibly and stably with low mechanical wear. It can quickly cut off short-circuit faults to ensure safe and stable power grid operation.
The fully sealed integrated structure with professional anti-corrosion treatment provides great waterproof, dustproof and anti-aging performance. It works steadily in humid, high-altitude, polluted and other harsh outdoor environments.
With compact structure and lightweight design, the equipment is easy to install on site and requires minimal daily maintenance, effectively reducing power distribution operation costs.
As mainstream protective equipment for 12kV outdoor power systems, ZW32-12/630 features high safety and stable performance. We provide global customers with factory direct supply, complete certifications and professional after-sales service.

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.
