MIDA-80B 10KA 2Pole 4Pole 80Amp 300mA Type B RCD RCCB Leakage Residual Current Circuit Breaker

Type B RCCBs, in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents. Reducing the risk of fire and/or electrocution through automatic disconnection of the electrical supply relies on the selection of the correct type of RCCB MIDA-80B.

Application 

EV & PV installations

Frequency converters

UPS installations

High-frequency power converters

Building site power supply cabinets

Function 

Type B Circuit Breaker Control electric circuits.

Protect people against indirect contacts and additionalprotection against direct contacts.

Protect installations against fire hazard due to insulation faults.Residual current circuit breakers are used in housing, tertiarysector and industry Selection Detectable wave form

B class Tripping is ensured for sinusoidal AC residual currents pulsed DCresidual currents,

currents and for smooth directresidual currents, whether applied suddenly or increasing slowly.

Tripping sensitivity 30mA -additional protection against direct contact MIDA-80B

Tripping time Instantaneous,It ensures instantaneous tripping (without time- delay).

Construction and Feature

Elegant appearance; cover and handle in arc shape make comfortable operation.

Contact position indicating window

Transparent cover designed to carry label.

In case of overload to protect circuit, RCCB handle trips and stays at central position, which enables a quick solution to the faulty line. The handle cannot stay in such position when operated manually. Provides protection against earth fault/leakage current and function of isolation.
