Specification

Residual current circuit breaker with overload protection(RCBO)
Brand Name: Meba
Model Number: DZ30L-32
Type: Residual Current Circuit Breaker or Residual Current Device
Poles Number: DPN

Specification：

1. DPNL(DZ30L)earth leakage circuit breaker is used for the protection, against electrical leakage in the circuit of 50Hz or 60Hz, rated voltage single-phase 240V, three-phase 415V, rated current up to 32A.

2. When somebody gets an electric shock or the residual current of the circuit exceeds the fixed value, the ELCB can cut off the power within the time of 0.1s automatically protecting the personal safety and preventing the equipment from the fault resulted from the residual current

3. With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switch over of the circuit under normal conditions. It conforms to IEC/EN 61009

Merits：

Good quality , high breaking capability, updated structure,quick trip and guide installation, competitive price,excellent and safe performance,beautiful and compact appearance, etc .
