Residual current circuit breakers (RCCB) switch off the power supply when dangerously high fault currents occur. They thus protect persons, animals and installations. DFS 4 are two- or four-pole residual current circuit breakers for single- or three-phase mains. In the standard version, the compact devices are four pitch units narrow. They are available with many different residual current types and designs at rated currents up to 125 A. The large double-level terminals can also accommodate large conductor cross-sections. The tripped position of the multi-function switching toggle facilitates troubleshooting. The free labelling software helps with labelling. Type B switches are universal current sensitive at frequencies from 0 Hz (smooth DC residual currents) to 150 kHz. They are increased surge current and thunderstorm resistant. Residual current circuit-breakers of the SK series stand for residual current protection and high system availability. They are characterised by a lower response sensitivity at higher frequencies. The SK characteristic is optimised for systems in which no fire protection is required. Units in standard version are designed for monitoring circuits with a rated voltage of 230 V/400 V and a rated frequency of 50 Hz. Properties: high immunity to operational leakage and residual currents at frequencies from 1 kHz
all-current sensitive for residual currents with frequencies and mixed frequencies from 0 Hz (smooth DC) to 150 kHz
mains voltage-independent tripping for residual currents of type A
voltage-dependent detection of smooth DC residual currents and AC residual currents with frequencies not equal to 50/60 Hz
full functionality with mains voltages from at least 50 V AC on any two active conductors
small size for all rated currents
high short-circuit resistance
double-level terminals on both sides for large conductor cross-section and busbar connection
switching position indicator
viewing window for labelling labels
multi-function switching toggle with three positions: &quot
on&quot
, &quot
off&quot
, &quot
triggered&quot

Connection C1 neutral position left
Mounting type: quick-fixing on mounting rail
Mounting position any
Feed preferably from above
Areas of application: Commercial and industrial installations with TN-S, TT and TN-C-S systems in which power electronics equipment without galvanic isolation is used, e.g. frequency converters, switching power supplies, high-frequency converters. Photovoltaic and UPS systems with transformerless inverters
Notes: suitable for use in 50 Hz AC mains
RCCB for other frequencies on request
Not intended for use in DC mains and on the output side of controlled electrical equipment such as frequency converters.
