Description

GYL9-AC Type AC RCCB

The GEYA GYL9-AC is a Type AC residual current circuit breaker for sinusoidal AC residual-current detection. Use it where Type AC protection is specified after assessing the connected loads and applicable installation requirements.

Residual-Current Coverage

The published Type AC scope is limited to sinusoidal alternating residual currents.

Selection Boundary

Confirm the expected residual-current waveform before selection. If it falls outside the published Type AC scope, select a residual-current type that matches the assessed waveform.

Ratings and Configuration

Catalogue options include 230/240 V or 400/415 V, 16 to 100 A across nine listed current ratings, 30/100/300 mA, and 1P+N or 3P+N. Available combinations depend on the selected order configuration; contact GEYA for the complete ordering matrix.

Installation and Service Data

  • TH35-7.5 DIN-rail mounting and IP20 degree of protection
  • 2.5 N·m terminal tightening torque
  • 1-35 mm² conductor capacity
  • Dual-busbar wiring and residual-current fault indication
  • 10,000 mechanical and 4,000 electrical operating cycles

Protection Coordination

The GYL9-AC is an RCCB for residual-current protection. Coordinate separate overload and short-circuit protection for the circuit.

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 required order configuration with GEYA.

FAQs

Which residual-current waveform can the GYL9-AC detect?

The published Type AC scope covers sinusoidal alternating residual currents.

Does the GYL9-AC cover residual-current waveforms other than sinusoidal AC?

No. Its published Type AC scope is limited to sinusoidal AC residual currents.

When should another RCCB type be selected?

Select another residual-current type when the assessed waveform falls outside the published Type AC scope.

Which rated-current and residual-current options are listed?

Rated-current options are 16, 20, 25, 32, 40, 50, 63, 80 and 100 A. Rated residual operating current options are 30, 100 and 300 mA.

Does the GYL9-AC provide overload or short-circuit protection?

No. It is an RCCB for residual-current protection. Coordinate separate overload and short-circuit protection for the circuit.

Are all rating combinations available?

The published values are catalogue options and do not establish every possible combination. Please contact GEYA for the complete current, residual-current and pole ordering matrix.
