Circuit breakers are an essential component of any electrical system, and PR21-2-1.00A-XX-S is designed to provide safe and reliable power distribution with maximum tenability of circuit protection. The PR21-2-1.00A-XX-S has a wide range of applications and can handle a variety of load requirements.

The PR21-2-1.00A-XX-S circuit breaker can be used in residential, commercial and industrial applications, including motor control circuits, motor starter installations, and control equipment. This device is well-suited for use in hot and humid environments and can tolerate the temperature variations found in locations where the ambient temperature can range from 10°F to 15°F.

The PR21-2-1.00A-XX-S circuit breaker is designed to provide overload and short-circuit protection via a three-pole type-S tripping system. The tripping system uses a combination of trip levels, including an adjustable trip arm, a thermal cut-off switch, and a thermal fuse. The adjustable trip-level will cut off power if the current exceeds the set trip level. The thermal cut-off switch is designed to protect the breaker in the event of an over-temperature situation, while the thermal fuse will cut off power if the current exceeds a set trip level.

The PR21-2-1.00A-XX-S circuit breaker is UL listed and CSA certified. This ensures that the circuit breaker meets all applicable safety and performance standards. Additionally, the circuit breaker is compliant with the requirements of NFPA-70E 130.2.1 and its associated annexes. This means that the PR21-2-1.00A-XX-S is suitable for use in industrial and commercial environments.

The PR21-2-1.00A-XX-S is designed to provide long-term reliability and protection of circuits. It features a Non-Interactive Neutral Trip Unit (NITU) that is designed to prevent alternating current from passing through the breaker in the event of an overload or short-circuit. The NITU also prevents false tripping and ensures that the breaker will trip and disconnect the circuit as soon as an overload or short-circuit is detected.

The PR21-2-1.00A-XX-S circuit breaker also features a Magnetic Trip Unit (MTU) which, when installed, is set to trip at a specific current level, protecting the circuit from dangerous and damaging overloads. The MTU also includes an adjustable, adjustable trip-level contact system, allowing the user to customize the breaker\'s protection.

In addition, the PR21-2-1.00A-XX-S circuit breaker also includes an integrated communications interface, allowing the user to easily connect external devices such as switches, alarms and monitoring systems, to provide additional safety and monitoring options.

The PR21-2-1.00A-XX-S circuit breaker is one of the most reliable, cost-effective and safe methods of providing power distribution and circuit protection. With its wide range of applications and long-term reliability, it is an essential component of any electrical system.
