IELH11-1-62F-60.0-01-V

Circuit breakers are designed to interrupt an electric circuit during a fault or overload condition. The IELH11-1-62F-60.0-01-V is a type of medium voltage circuit breaker, and it has a variety of applications and working principles that enable it to protect a variety of electrical systems.

This low-weight, pole-mounted circuit breaker is typically used in medium-voltage systems that have a usage of 50 to 60 Hz, operating at 36 kV. It is designed to provide continuous protection to the system in the form of short-circuit and overload protection. Additionally, it can be used to limit the installation of switchgears and auxiliary relays. Its mechanical interlock further limits the possibilities of a simultaneous closure of two or more poles of a circuit breaker, so as to prevent any kind of damage to the transformer or system.

The IELH11-1-62F-60.0-01-V circuit breaker features a minimum operating cycle time of 20 ms and a maximum of 210 ms, which allows for a quick response and action in case of emergencies. Additionally, its three-phase trip coil enables continuous and reliable operation, even during a fault condition. It also has a trip-bar indicator, which enables visual tripping and indicates when the breaker has tripped.

The operating principle of the IELH11-1-62F-60.0-01-V circuit breaker relies on the use of a toggle mechanism that connects a trip bar to a set of copper contacts. When the current draw exceeds a preset threshold, an electromagnet is activated which moves the trip bar, causing it to open the contacts, which interrupts the electric circuit and prevents further damage from occurring.

In addition to providing efficient overload and short-circuiting protection, the IELH11-1-62F-60.0-01-V circuit breaker also has the capability of providing indication of the condition of the breaker. This is done through the inclusion of a number of status indicators which display the system’s status, such as circuit trips, current load, and incoming voltage.

Overall, the IELH11-1-62F-60.0-01-V circuit breaker is a reliable and versatile device which can protect a variety of medium-voltage systems against overloads, short-circuits, and other harmful events. It is lightweight, easy to install, and utilizes a toggle mechanism which enables it to act quickly in emergency situations. Furthermore, its tripping indication makes it easy to monitor the operation and condition of the circuit breaker.
