IELK111-27320-8-V Circuit Protection

Circuit-breakers are essential components of electric power systems. They are designed to protect against short-circuiting, overloading and other hazards that can cause electric components to malfunction or even catch fire. The IELK111-27320-8-V is a circuit-breaker designed specifically for industrial applications. It is suitable for use in environments such as in factories, mines, generators, railways and power distribution systems.

The circuit-breaker is designed to operate automatically in response to an over-current or other dangerous event. It is similar in construction to other circuit-breakers that are designed for residential or commercial applications. It has a heavy duty enclosure and is designed to withstand harsh environmental conditions. It has a 240-volt AC voltage rating and a 9,000-amp current rating.

The circuit-breaker is triggered by an internal thermal overload relay. This relay is designed to detect an excessive current flow and activate the breaker. Internally, the thermal overload relay consists of two closely spaced contacts connected in series, with a set of bimetallic discs between them. When the current flowing in the circuit rises above the set temperature of the bimetallic discs, they will expand and open the contacts. This will cause the circuit-breaker to trip, immediately interrupting the flow of electricity and preventing further damage to the components.

The IELK111-27320-8-V is also designed to prevent unauthorized access to the equipment. It has a keyed reset mechanism to prevent tampering. When the circuit-breaker trips, the reset can only be activated by using the provided key. This ensures that only authorized personnel can reset the breaker, preventing any potential harm due to unauthorized access of the equipment.

In conclusion, the IELK111-27320-8-V is an industrial-grade circuit-breaker designed to protect electrical components from dangerous events such as short-circuiting, overloading and other hazardous conditions. It is suitable for use in hazardous environments and is equipped with a keyed reset mechanism for added security. The thermal overload relay detects excessive current and triggers the breaker, providing safe and reliable protection to the equipment.
