Circuit Breakers

Circuit Breakers are safety devices that can be used in a variety of applications. The R21-1REF. S00378305 model is a type of Circuit Breaker specifically designed for the industrial sector. This article will discuss the application field and working principle of this particular model.

Application Field

The R21-1REF. S00378305 model of Circuit Breaker is ideal for the industrial sector, due to its large capacity and high fault-clearance ratings. This model has been approved for use in the U.S., Canada, and Europe and is extremely common for industrial applications. It is suitable for high and low voltage applications, as well as in switched equipment, such as power transmission and distribution lines.

This model, in particular, is suitable for a variety of AC circuits including motor, lighting, and general purpose circuits. It is also suitable for DC circuits including rectifier, motor, and general purpose circuits. The R21-1REF. S00378305 Circuit Breaker is designed to protect people, devices, and buildings from potentially hazardous conditions by providing a control switch that shuts off the circuit if it detects a sudden overload.

Working principle

The R21-1REF. S00378305 model utilizes a voltage sensing mechanism to detect and interrupt abnormal current levels in the circuit. When the current level goes beyond the normal range, the solid-state voltage sensing mechanism determines an overload condition and trips the Circuit Breaker. The solid-state voltage sensing mechanism is triggered by a sudden change in voltage, which instantly trips the Circuit Breaker and interrupts the current flow.

The voltage sensing mechanism is integrated in a highly resilient thermoplastic enclosure to ensure the durability of the Circuit Breaker. The circuit breaker also features an integrated lockout mechanism, which prevents it from being reactivated until the power is removed from the circuit. This lockout mechanism is designed to protect workers from accidental reactivation.

The R21-1REF. S00378305 Circuit Breaker features a robust capability for controlling the current level when normally powered. It is designed to automatically reset when the power goes out and has a test switch to easily test the circuit breaker from time to time. Additionally, the breaker also includes an LED indicator to alert the user when it’s tripped.

The R21-1REF. S00378305 Circuit Breaker is an ideal solution for industrial applications due to its reliable performance, robust control capabilities, and easy installation. It can handle heavy-duty applications and is designed to protect against potentially hazardous conditions. This technology is widely used in a variety of industries and is sure to provide reliable protection for years to come.
