Chint Circuit Breaker DZ47LE32/2PC20 is a type of miniature residual current circuit breaker (RCB).
모델 의미
“DZ” stands for molded case circuit breaker.
“47” is the design serial number.
“LE” indicates a residual current operated circuit breaker, i.e., an earth leakage protection circuit breaker.
“32” represents a frame current of 32A, which is the maximum current that the circuit breaker can withstand.
“2P” means the pole number is 2 극, which can control both the live wire and the neutral wire simultaneously.
In “C20”, “C” refers to the tripping characteristic, which is suitable for conventional loads; “20” indicates a rated current of 20A, meaning the maximum current at which the circuit breaker can operate stably for a long time is 20A.
Main Parameters
Leakage Current: Usually 30mA (other values are optional for some specifications). When the leakage current in the circuit reaches this value, the circuit breaker will cut off the circuit quickly.
Breaking Capacity: Generally 6kA, which means the circuit breaker can cut off a shortcircuit current of 6kA within a specified time when a fault such as a short circuit occurs in the circuit.
Rated Voltage: 230VAC.
Leakage Protection Type: 교류, suitable for AC circuits.
Leakage Release Type: Electronic.
Functional Feature
누출 방지: When a leakage occurs in the circuit or a person gets an electric shock, it can quickly cut off the power supply within 0.1 seconds to protect personal safety.
과부하 보호: When the circuit load is too large and the current exceeds the rated current, it will automatically cut off the circuit to prevent the line from being burned out.
ShortCircuit Protection: It can quickly cut off the shortcircuit current to avoid electrical equipment damage, fires and other accidents caused by short circuits.
응용 시나리오
It is suitable for lighting and socket circuits in places such as homes and commercial buildings. It can prevent leakage risks in humid environments, such as kitchens, bathrooms, and airconditioning circuits. It can also be used as the main switch in distribution boxes to provide fullhouse leakage protection.
