Industrial and Commercial Circuit Breakers FAQ

What are the voltage and current ratings available for your industrial and commercial circuit breakers?

Our circuit breakers come in a wide range of voltage and current ratings to accommodate various industrial and commercial applications. Specific ratings are detailed in the product descriptions on our website.

The Voltage Ratings typically range from 240V to 690V AC, with some models supporting up to 1,000V.  The Current Ratings vary from 10A to 6,300A, depending on the breaker type and application.

Do you offer resources for the selection and maintenance of industrial and commercial circuit breakers?

Yes, we provide detailed guides and resources to help you select and maintain the appropriate circuit breakers for your needs. Examples include Schneider Electric’s EcoStruxure Power Selector and Allen-Bradley’s Circuit Breaker Selection Tool.  Our team is also available for consultation to ensure optimal product selection and maintenance.

Detailed technical manuals for each breaker model include installation, configuration, and operating guidelines. These manuals are available on the manufacturers’ websites and provide essential information on voltage, current ratings, and wiring requirements.

What types of industrial and commercial circuit breakers do you offer (e.g., molded case, air circuit, vacuum)?

We offer a variety of circuit breakers, including molded case, air circuit, and vacuum circuit breakers. Each type is designed to meet specific operational requirements and standards.

What are the environmental operating limits of your industrial and commercial circuit breakers (temperature, humidity, altitude)?

Our circuit breakers are designed to operate within a broad range of environmental conditions. Specific operating limits, including temperature, humidity, and altitude, are provided in the technical specifications of each product.

Operating Temperature: Typically rated from -25°C to +70°C (-13°F to 158°F).

Storage Temperature: Most of these breakers can be stored between -40°C to +85°C (-40°F to 185°F)

Humidity: Generally rated for operation in 95% relative humidity (non-condensing) at 40°C (104°F) for all brands.

Altitude: Circuit breakers from Allen-Bradley, Siemens, and Schneider Electric are typically rated for operation up to 2,000 meters (6,561 feet) above sea level without derating. For altitudes above 2,000 meters, derating factors may apply to the current rating and insulation properties.

What is the arc flash rating for your products?

The arc flash ratings for our circuit breakers vary depending on the model. Detailed information can be found in the product’s technical documentation, ensuring compliance with safety standards.

Allen-Bradley, Siemens, and Schneider Electric circuit breakers are typically designed to withstand arc flash conditions in compliance with IEEE 1584 and NFPA 70E standards. Many models have arc flash withstand ratings up to 65 kAIC (kiloamps interrupting capacity) or more, depending on the system voltage and configuration.
