ABB OS125GB03P OS Series Switch Fuses Parameters

1. Rated Voltage

The switch fuse is designed to operate at a specific rated voltage, typically 400V AC. This is the standard voltage under which the device can function safely and efficiently.

2. Rated Current

It has a rated current of 125A. This indicates the maximum continuous current that the switch fuse can carry without overheating or suffering damage.

3. Breaking Capacity

It can interrupt short - circuit currents up to a certain value, usually specified in kilo - amperes (kA). For example, it may have a breaking capacity of 50kA, which means it can safely cut off short - circuit currents of this magnitude.

4. Pole Configuration

It is a 3 - pole switch fuse, as indicated by the "GB03P" in the model number. This configuration is suitable for three - phase electrical systems, providing protection for each phase.

5. Insulation Resistance

The switch fuse has a high insulation resistance, typically measured in mega - ohms (MΩ). This ensures proper electrical isolation and prevents leakage currents.

6. Degree of Protection

The enclosure offers a certain degree of protection against dust and water, usually represented by an IP (Ingress Protection) code. For instance, it could have an IP54 rating, meaning it is protected against limited dust ingress and splashing water from any direction.
