Description

Product Overview

GEYA GYR9LE RCBO (Residual Current Circuit Breaker with Overcurrent Protection) combines residual-current, overload and short-circuit protection for AC 50/60 Hz distribution circuits. The catalog lists 6–40 A rated current, 230/400 V or 240/415 V rated voltage, and 1P+N or 3P+N configurations. At IΔn, the listed residual-current breaking time is ≤0.1 s under the catalog test condition.

The GYR9LE catalog lists Type AC, Type A and Type B residual-current options, B/C/D tripping curves, 6000 A rated short-circuit capacity and a leakage-trip indicator. It also states support for both wiring directions. Select the residual-current type and verify the circuit and equipment requirements for the intended installation.

Frequently Asked Questions (FAQs)

1. What is the GYR9LE RCBO?

The GYR9LE is a Residual Current Circuit Breaker with Overcurrent Protection. It is a comprehensive safety device that combines the functions of an MCB and an RCCB, providing a unified solution for earth leakage, overload, and short-circuit protection.

2. What functions does it provide?

The device combines residual-current, overload and short-circuit protection. The catalog lists a residual-current breaking time of ≤0.1 s at IΔn under the stated test condition.

3. What are the key parameters affecting selection?

Key selection factors include the rated current (6A to 40A), sensitivity or rated residual operating current (30 mA, 100 mA or 300 mA), pole configuration (1P+N or 3P+N), and the tripping curve (B, C, or D) based on your specific load characteristics.

4. What options are currently available?

You can select from AC, A, or B type residual current protection to handle different leakage waveforms. The series is available in various current ratings up to 40A, and multiple sensitivities (0.03A, 0.1A, 0.3A).

5. What standards does it meet and which markets is it designed for?

The GEYA catalog lists IEC/EN 61009-1 and GB/T 16917.1 and states RoHS 2.0 compliance. Check the certification documents for the selected configuration and destination market.

6. What are the installation precautions?

The device mounts easily on a standard TH35-7.5 DIN rail. Ensure a tightening torque of 2.0 N·m for the terminals to prevent arcing. It supports reversible wiring and accommodates cable sizes ranging from 1 to 25 mm².
