IEG111-27489-3-V Circuit Protection

Circuit breakers are essential components of virtually every modern electrical system. They are designed to protect electrical circuits from dangerous overloads and short circuits. They provide a method of breaking a circuit quickly and safely to prevent catastrophic damage to the electrical system. The IEG111-27489-3-V is a type of circuit breaker that is designed for a wide range of applications and offers a unique combination of features and safety measures.

The IEG111-27489-3-V is a three pole, self-closing, snap-action, direct-mounted electrical breaker. It is designed with a NEMA three phase power panel lockout switch and a color-coded LED display. The unit has an adjustable trip setting for overloads up to 20A. The unit also features a quick make/break mechanism for fast tripping and a T-APRONC current release feature that temporarily prevents ground faults due to an overload. The IEG111-27489-3-V also includes a high performance microprocessor that can detect short circuits up to 2 cycle.

The IEG111-27489-3-V is designed for a wide variety of applications ranging from residential to industrial. It is suitable for use in buildings, water treatment plants, and other places where sensitive electronic and electrical equipment are present. It is also often used in automotive applications such as in ignition systems, starter, and alternator wiring. The IEG111-27489-3-V can also be used in solar power systems, wind turbines, and other renewable energy power sources.

The range of applications for the IEG111-27489-3-V is matched by its reliable performance in those applications. It features an adjustable trip setting that can be adjusted to match the specific needs of the application. Its quick make/break mechanism enables it to quickly shut off the circuit in overload or short-circuit situations. The T-APRONC current release feature can prevent ground faults due to an overload. The LED display offers additional monitoring capabilities.

The working principle of the IEG111-27489-3-V is relatively simple. When an overload or short circuit occurs, the contacts on the device heat up quickly. The heat causes a bimetallic disc to expand, breaking the circuit. This quickly shuts off the power to the affected area, preventing any further damage. When the temperature of the bimetallic disc cools down, it contracts, allowing power to be restored.

The IEG111-27489-3-V is a versatile circuit breaker that can be used for a wide variety of applications. It offers a unique combination of features and safety measures including a quick make/break mechanism, a T-APRONC current release feature, and an LED display. It employs a simple working principle that enables it to quickly shut off the affected circuit in the event of an overload or short circuit. It is a reliable and safe choice for protecting sensitive electronic and electrical equipment.
