Product Description

LZCG530-10 50/5A 5P10 three phase Protection current transformer with 15VA burden

GFUVE Multilin transformer protection relays are suitable for different transformer protection applications, including medium voltage and high voltage transformers of any size, dual secondary transformers, auto-transformers, three-winding transformers, transformers with dual-breaker terminals.
three-phase current transformer for motor protection. Three-phase current transformer, Features Low cost More than 10 standard size Chassis mounting pattern Applications Application for current monitor of AC motor, illumination device, air compressor. And HVAC temperature control, electrical energy manage,building control system.

LZCG series Cast Resin Straight-Through Current Transformer is suitable for current measurement and microcomputer protection of electrical equipment in 10KV and 35KV AC power system. It is widely used in not only compact fully insulated ring network switchgears such as ABB-Safe Ring/Safe Plus, Unstitch, Schneider RM6, SM6, Siemens 8DJ10/8DH10, Simosec, FBX, Fluokit, Omar Garbo GA, GAE; SEL TPS(Q); VEI Unifluorc; Eaton SVS/12 ring network, but also cable distribution boxes because of its small size, light weight, operable and convenient installation. It is very convenient that the transformer can be directly installed at the inlet and outlet cables.
 

New magnetic material is taken to be the core of the current transformer, which has high magnetic permeability, low saturation magnetization and good stability. Therefore, the measuring accuracy is higher and the instrument security factor is lower. Since the high quality silicon processed by advanced technology is taken to be the core of the protection windings, which assured the accuracy limit factor is higher.

The semicircular ring core and secondary windings are vacuum poured by high quality epoxide resin in the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance.Small size, light weight, small footprint, fixed in the ring network switchgear cable.The cable can cross the current transformer through its internal poles quickly and uniformly.

The Cast Resin Straight-Through Current Transformer can be divided several kinds according to the various current ratio, accuracy and rated loads. The specific parameters are showed in the corresponding to each model parameter tables.
