Description

Residual current circuit-breakers, four-pole, 40 A, 0,03 A, Type A, mains monitoring, N left

Function

Type A residual current circuit-breakers detect pulsating direct current and alternating current. Thanks to the mains monitoring function, our NU RCCBs also trip in the event of input-side mains disturbances, such as a neutral conductor interruption. This reliably protects electrical equipment against overvoltage damage.

Properties

tripping not dependent on mains and auxiliary voltage, sensitive to AC residual currents and pulsating DC residual currents (type A) , compact design for all rated currents, high short-circuit resistance, double-sided two-tier terminals for large conductor cross-section and busbar, switch position indicator, viewing window for labels, multifunction switch toggle with three positions: "on", "off" and "tripped", Neutral conductor position left

Installation

quick fastening to mounting rail, any installation position, supply from any direction

Applications

Power supplies to residential and purpose-built buildings as well as industrial facilities with TN-S, TT and TN-C-S networks. In IT networks, the residual current circuit-breakers of this series can be set to switch off in the event of a second fault, Excluded is the application in TN-C systems and for the protection of installations in which electronic equipment could generate smooth DC currents or residual currents with frequencies other than 50 Hz. Comprehensive protection is not provided in this case. For these applications we recommend our AC/DC sensitive residual current circuit-breakers (Type B or B+).
