DAB7LN-40 series DPN Residual current operation circuit breaker(RCBO)

>> Introduction

DAB7LN -40 residual current circuit breakers are small devices designed with high breaking capacity (6kA) and they are suitable for the disconnection of neutral lines.

The circuit breakers are widely used in AC50H low-voltage electrical systems with a rated voltage of 230V and rated current of no more than 40A. This effectively protects people from electric shock and circuit equipment form overcurrent or short circuiting.

These circuit breakers are also suitable for preventing fire hazards as a result of ground currents caused by insulation damage of electrical equipment.

Installation method: Using 35mm guide rail according to IEC standard
Terminal type: Dual-purpose terminal can be connected to the bus bar and conductor.
Terminal connection ability: conductor 1-25mm2, bus bar thickness 0.8-2mm
Guide rail: DIN35guide rail

Functions of DAB7LN-40 residual current circuit breaker
Short circuit protection, overload protection and isolation.
