STID-63 RCCB

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.

100A 2p 4p Multifunctional RCBO

STSF2-100 100A 2p 4p Multifunctional RCBO is suitable for AC 50/60Hz, rated in a circuit with a voltage of 230V-400V and a rated current of 100A, when aperson is electrocuted or the power grid leaks. When the leakage, overvoltage, and undervoltage reach the set values, the residual current circuit breaker can quickly operate in a very short period of time quickly cut off the power supply. When the monitoring temperature of the residual current circuit breaker reaches the set value, the monitoring ground wire is not connected. When connected, the product emits an alarm sound to protect the safety of personnel and electrical equipment, and can avoid Prevent damage to equipment caused by overvoltage in the power grid. Has overload, short circuit, leakage, overvoltage Undervoltag......
