RCBO 63A 30ma DZ47LE-63

Introduction:

The RCBO 63A 30mA series residual current circuit breakers (RCCBs) are suitable for AC 50Hz circuits. The rated operating voltage is 230V for single-pole two-wire and two-pole configurations, and 400V for three-pole, three-pole four-wire and four-pole configurations. The rated current is up to 63A.
An RCBO with overvoltage protection also provides additional protection against excessive voltage caused by grid faults.
The CNTN-manufactured RCBO 63A 30mA features high breaking capacity, wide accessory compatibility, compact size, anti-slip design, and stable reliability.
The RCBO 63A 30mA specification is often used in places where high protection against electric shock is required (such as household socket circuits).
When overcurrent protection devices fail to function properly, RCBOs can also prevent fires caused by persistent ground faults. RCCBs with overvoltage protection also provide additional protection against excessive voltage caused by grid faults.
RCBO 63A, 30mA DZ47LE-63 refers to the DZ47LE-63 series of products, which includes residual current operated circuit breakers (RCBOs) with overcurrent protection, with specifications of 63A and 30mA.

“A” (ampere) is a unit of current; “63A” indicates the rated operating current of the RCBO, meaning that under normal operating conditions, the maximum current this component can continuously carry is 63 amperes.

“mA” (milliampere) is another unit of current; 1 ampere equals 1000 milliamperes.
