Circuit Breakers

IUGH211-1REC4-9415-2 application field and working principle

Circuit breakers are commonly used in electrical power distribution systems, electrical apparatus, and electronic equipment to protect against short circuit, overload, or ground fault conditions that could cause energy surges or damage. They are typically rated according to their ability to withstand short circuit currents. The IUGH211-1REC4-9415-2 circuit breaker is an example of a type of circuit breaker that provides superior protection against short circuiting.

The IUGH211-1REC4-9415-2 circuit breaker is designed for use in industrial environments where higher short circuit currents are likely to be encountered. It is suited for use on AC power lines and motor branch circuits up to 1200 amperes at 100 percent rated current. It is also rated for DC power line applications up to 600 amperes. Furthermore, it offers a wide selection of trip current settings for both AC and DC applications.

The IUGH211-1REC4-9415-2 is a fully integrated thermal/magnetic trip unit that includes thermal protection, short circuit protection, and conveyor duty protection. Its thermal protection feature corresponds to the temperature rise in the circuit breaker during normal operation, providing automatic protection against overloads and short circuit conditions. This is especially important in an industrial environment where high levels of current can cause substantial temperature increases.

The short circuit protection feature of the IUGH211-1REC4-9415-2 circuit breaker offers the ability to detect and respond to an instantaneous interruption in the electrical current flow. This action is governed by the design of the relay coil and the current interrupting capacity of the breaker. When an excessive current flow is detected, the breaker will trip and shut down the circuit. The trip current can be adjusted to the specific short circuit current level required for a particular installation.

The IUGH211-1REC4-9415-2 circuit breaker also contains a Conveyor Duty protective feature. Conveyor duty protection is designed to protect against conditions that can cause excessive motor starting current and can damage the motor windings. With this feature, a motor can be started without an attendant waiting for the breaker to trip and stop the motor if it should overload. The breaker will trip within a few seconds and a signal will be sent to the control panel to shut down the motor.

The IUGH211-1REC4-9415-2 circuit breaker is an effective and reliable tool for protecting the system from overloads, short circuits, and other hazardous conditions. It is extremely versatile and offers a range of trip current settings to meet the specific requirements for virtually any installation. It is designed to be reliable and easy to use, and is well suited for use in industrial applications.
