China Residual Current Circuit Breaker Manufacturer, Supplier, Factory

STID-63 RCCB, full name Residual Current Circuit Breaker (STID-63 RCCB), is an electrical safety device specifically designed to prevent electrical fires and electrocution accidents. It mainly monitors the residual current in the circuit, i.e. the difference between the current of the fire line and the zero line. When this difference (usually caused by leakage) exceeds a preset value, the STID-63 RCCB will automatically cut off the circuit in a very short period of time, thus protecting the personal safety and the equipment from damage.

The 4P 40A/10mA Residual Current Circuit Breaker is a residual current circuit breaker with 4 poles (i.e., 3-phase Fire and Zero wires) that is rated at 40 amps and is capable of automatically cutting off the circuit when the residual current in the circuit is detected to be at or above 10 milliamps. The device is mainly used to prevent electrical fires and electrocution accidents and to safeguard personal and equipment safety.

SONTUOEC is one of the Chinese suppliers/manufacturers specializing in the production of various small electrical appliances ST264J is used in AC50 / 60HZ two poles 230V, four poles 400V,rated current up to 63A, It can automatically and immediately cut off power supply once someone suffers from electric shock or leakage current above specified . It can effectively protect personal security and avoid the damage to equipment. The residual current operated circuit breaker can also function as overload and short-circuit protection and unfrequent changeover of line under normal condition. The product is suitable for industry, business, building, residence ,etc. It is conformity with IEC61008-1 standards.

SONTUOEC is one of the Chinese suppliers/manufacturers specializing in the production of various small electrical appliances. STID-63 Series RCCB 230V 63A Residual Current Circuit Breaker can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunkline.Thus it is suitable to avoid the shock hazard and fire caused by earth leakage.It can be used in circuits up to single phase 240V,three phase 415V,50 or 60Hz. Compliant with IEC61008-1 standard.

This 4P 63A /30mA RCD AC Type triggers the RCD's internal disconnecting mechanism, causing the RCD to quickly cut off the power supply, thus protecting the safety of electrical equipment and personnel.

RCCB B Model Residual Current Circuit Breaker protects in the event of contunuous fault current on three phase networks.It usually is used in the field of Recharging Station,Medical Apparatus and Instruments, Controllers and Variable Speed Drives,Batter Charges and Inverters(DC)...STID-B complys with IEC/EN61008-1 and IEC/EN62423 standard.
