Protective Devices
Add-on Residual Current Protection Unit PBSM
• Add-on residual current unit
• Line voltage-independent tripping
•
By combining this device with a top-quality miniature circuit breaker type PLS.
(exept PLSN.) a top-quality RCBO unit (combined RCD/MCB device) is formed.
• Rated current 40 and 63 A
• Permits combinations with a variety of characteristics thanks to the differ-
ent rated currents and characteristics of the PLS.-miniature cirvuit breakers
which can be connected
• Comrehensive range of accessories suitable for subsequent installation
onto PLS.
• Type -A: Protect against special forms of residual pulsating DC which have
not been smoothed.
• Type -G: High reliability against unwanted tripping. Compulsory for any cir-
cuit where personal injury or damage to property may occur in case of
unwanted tripping (ÖVE-EN1, Part1, §12.14).
• Type -S: Selective residual current device, either sensitive to AC, type -S,
or sensitive to pulsating DC, type -S/A, for protection against special forms
of residual pulsating DC which have not been smoothed. Compulsory for
systems with surge arresters downstream of the RCD (ÖVE-EN1, Part 1,
§12.15).
