Schneider circuit breaker ratings
Schneider Electric is a well-known manufacturer of circuit breakers, and their products have various ratings depending on the type, size, and application. Here are some common ratings for Schneider circuit breakers:
Current Ratings:
- Ampere (A) ratings: Schneider circuit breakers are available in a range of current ratings, from 15A to 4000A.
- Kilovolt-Ampere (kVA) ratings: Schneider circuit breakers are also rated in kVA, which is a measure of the circuit's power handling capacity. Typical kVA ratings range from 1.5 kVA to 2500 kVA.
Voltage Ratings:
- Voltage (V) ratings: Schneider circuit breakers are available for various voltage ranges, including:
- 120/240V (residential and commercial applications)
- 208/240V (industrial and commercial applications)
- 277/480V (industrial and commercial applications)
- 600V (industrial and commercial applications)
Frequency Ratings:
- Frequency (Hz) ratings: Schneider circuit breakers are designed for operation at specific frequencies, including:
- 50/60Hz (standard frequency for most residential and commercial applications)
- 60Hz (standard frequency for North American applications)
- 50Hz (standard frequency for European and other international applications)
Inrush Current Ratings:
- Inrush current (Iin) ratings: Schneider circuit breakers are designed to handle inrush currents, which are high currents that occur when a circuit is first energized. Typical inrush current ratings range from 10 to 100 times the normal current rating.
Short-Circuit Current Ratings:
- Short-circuit current (Isc) ratings: Schneider circuit breakers are designed to withstand short-circuit currents, which are high currents that occur when a fault occurs in the circuit. Typical short-circuit current ratings range from 10 to 100 times the normal current rating.
Arc Fault Ratings:
- Arc fault (AF) ratings: Schneider circuit breakers are designed to detect and interrupt arc faults, which are abnormal electrical discharges that can occur in a circuit. Typical arc fault ratings include:
- Class A (residential and commercial applications)
- Class B (industrial and commercial applications)
- Class C (high-voltage industrial applications)
Other Ratings:
- Temperature ratings: Schneider circuit breakers are designed to operate within specific temperature ranges, typically from -40°C to 40°C (-40°F to 104°F).
- Environmental ratings: Schneider circuit breakers are designed to operate in various environmental conditions, including humidity, vibration, and shock.
Please note that these ratings may vary depending on the specific Schneider circuit breaker model and application. It's always recommended to consult the manufacturer's documentation and specifications for the specific product being used.
