Description

GYL9-A-SI Type A-Si RCCB

The GYL9-A-SI is a Type A RCCB with the catalogue Type Si operating-time bands. Type A detection covers sinusoidal AC and pulsating DC residual currents. Use the complete timing table and the selected device ratings when evaluating protection coordination.

Residual-Current Detection

The Type A characteristic is intended for sinusoidal AC and pulsating DC residual currents. Select a different residual-current type when the installation requires detection of waveforms outside this scope.

Type Si Operating-Time Characteristic

The operating time changes with the applied residual current. The catalogue specifies separate Type Si ranges at IΔn, 2IΔn, 5IΔn, 5–200 A and 500 A; use the complete table rather than a single combined time value.

Ratings and Configuration

Rated current – 16, 20, 25, 32, 40, 50, 63, 80 and 100 A.
Rated residual operating current – 30, 100 and 300 mA.
Voltage and poles – 230/240 V or 400/415 V; 1P+N or 3P+N.

These values are catalogue options and do not establish that every combination is available. Confirm the complete ordering matrix for the required configuration.

Installation and Protection Boundary

Installation – TH35-7.5 DIN-rail mounting, IP20, 2.5 N·m tightening torque and 1–35 mm² conductor capacity.
Connection and indication – Dual-busbar wiring and residual-current fault indication.
Service life – 10,000 mechanical and 4,000 electrical operations.

The GYL9-A-SI is an RCCB and does not provide overload or short-circuit protection. Select and coordinate suitable protective devices separately for the installation.

Reference Standards and Catalogue

The GYL9 catalogue lists IEC/EN 61008-1 and GB/T 16916.1 as reference standards. Review the GYL9 catalogue and confirm the complete ordering matrix with GEYA.

FAQs

Which residual-current waveforms can the GYL9-A-SI detect?

As a Type A RCCB, it is intended for sinusoidal AC and pulsating DC residual currents.

What does Si mean on the GYL9-A-SI?

Si identifies the catalogue operating-time bands shown for this model. Use the complete timing table when evaluating coordination.

What are the published Type Si operating-time bands?

The catalogue lists 0.09–0.15 s at IΔn, 0.05–0.15 s at 2IΔn, and 0.04–0.15 s at 5IΔn, 5–200 A and 500 A.

Does the GYL9-A-SI guarantee selective coordination?

No. Coordination depends on the complete system design, device ratings, residual-current settings and time-current characteristics.

Which ratings are listed for the GYL9-A-SI?

Catalogue options include 16, 20, 25, 32, 40, 50, 63, 80 and 100 A; 30, 100 and 300 mA; and 1P+N or 3P+N. Confirm the complete ordering matrix for the required combination.

Does the GYL9-A-SI provide overload or short-circuit protection?

No. It is an RCCB; suitable overload and short-circuit protection must be selected separately.
