China External Circuit Breaker Manufacturer, Supplier, Factory

Wholesale LR9 thermal overload relay manufacturer, 32A/690V, thermal setting range 6.4-32A, selectable tripping class 5-10-20-30, for protection of 3-phase motors 3-15KW@400V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustement dial, buttons for test, stop and reset as well as manual-automatic reset selector, dipswitches for tripping class selection, a flag indicator and 2 auxiliary contacts 1NO+1NC for fault signalling. With a large thermal setting range 6.4-32A, a selectable tripping class 5-10-20-30 and phase unbalance detection, it protects motors 3 to 11KW@400V. Connection by screw clamp terminals, it connects directly to the bottom terminals of 3-pole contactors LC1D09-D38. Mounting on DIN rail or screw fixing, separated from contactor, with use of the terminal block LAD7B205 (to be ordered separately). Multi-standards certified (IEC, UL, CSA, CCC), Green Premium compliant (RoHs/Reach).

China XUCKY Electric customized GV2-ME motor protection circuit breaker is mainly used for the overload and short circuit protection of the motor in AC 50/60Hz, up to 660V, 0.1-80A power circuit.

China XUCKY Electric customized JDZX11 Type Voltage Transformer is high quality with ASTA, KEMA, SEMKO, CE, CB, ROHS certificate. JDZX11 Type Voltage Transformer are devices that are used to step down and decrease the voltage of a system to a level that is considered safe. It operates by allowing energy meters to monitor the operation of electrical connections, which may have a higher voltage than usual to function correctly.

The composite post insulator can be effectively used the narrow corridor to drive down the power supply, which is suitable for thetrans formation of the city network technology and high voltage power line service.
The composite post insulator has features of good hydrophobicity anti-ageing, anti-leakage trace and electric erode proof, tensile strength and bending strength, strong mechanical strength, shock resistance good quake proof and brittle failure proof, light weight. Easy to installation.

JSZVR type voltage transformer of epoxy resin cast insulated and totally-enclosed structure is intended for power measurement, current monitoring and relay protection in the line of up to 12 kV and AC 50-60 Hz.
●It is applicable to air insulated switchgear
●It conforms to GB1207 and lEC60044-2 standards

XUCKY NDM1 Moulded Case Circuit Breaker (NDM1, hereinafter referred to as MCCB), is new circuit breakers which have been designed and developed by the company using international advanced technology. The circuit breakers are of the following characteristics: compact size, high breaking capacity, short arc-over distance and shakeproof, is ideal products applied on land or ships. The rated insulation voltage of the circuit breaker is 800V (500V for NDM1-63), it is suitable for the distribution network of AC 50Hz / 60Hz, rated working voltage of 690V and rated current of 1250A, to distribute power and protect circuit and power equipment from being damaged caused by overload , short-circuit, under-voltage and other fault. Also for protection infrequent conversion of the circuits and infrequent start of motor and overload, short circuit, under voltage.
