ABB GSN201 is an electronic residual current circuit breaker with overcurrent protection (RCBO). It combines residual current, overload and short-circuit protection in a single-module 1P+N device for final circuits in distribution boards.
This page retains 10 model-and-order-code records: five GSN201 L and five GSN201 entries. The documented protection type and ratings below apply to the GSN201 variants described by ABB, rather than to other ABB RCBO families.

GSN201 L & GSN201: Documented Ratings
ABB’s March 2013 GSN201 brochure describes Type AC, C-curve, 1P+N devices with 6–25 A rated currents, 30 mA rated residual operating current and 230/240 V, 50/60 Hz supply ratings. The current table contains the 6, 10, 16, 20 and 25 A entries for each group.
The brochure distinguishes rated short-circuit capacity Icn under IEC/EN 61009-1: 4.5 kA for GSN201 L and 6 kA for GSN201. These are group-specific values. Do not apply the 6 kA value to the L group or confuse Icn with a differently defined short-circuit rating.
Protection Type & Selection Boundaries
The referenced GSN201 brochure specifies Type AC and cites IEC 61009-1 and GB 16917.1. It does not establish Type A, F or B characteristics for the records on this page. Select the residual current type required by the actual load, installation rules and applicable regional documentation; do not infer suitability for electronic loads from the RCBO name alone.
Check rated current against the circuit design, C-curve requirements, residual operating current, supply voltage/frequency and prospective short-circuit current. Also confirm the complete code, connection arrangement, neutral requirements, installation space and permitted accessories. A different region, document revision or variant requires its own evidence.
