Circuit breakers are a type of electrical protection device that are used to cut off any electrical circuits when a certain level of current is passed through. The IELHK111-33660-1-V is a single-phase, air insulated, three-pole circuit breaker designed for the protection of low voltage AC circuits. The unit is equipped with an overcurrent protection device that is capable of automatically switching on and off the circuit whenever the current level exceeds a certain pre-determined value.

Applications

This circuit breaker is suitable for use in many applications. Industrial installations, such as refineries, chemical plants, steel mills, and motor control centers often employ the IELHK111-33660-1-V as a means of circuit protection. The unit can also be used in a wide range of residential applications such as a circuit breaker box. This unit is ideal for protecting branch circuits and can be used to provide protection from overloads, unwanted short-circuits, and earth leakage.

Working Principle

The IELHK111-33660-1-V operates using the principle of thermal-magnetic tripping. When the current drawn by the circuit exceeds a certain level, the magnetic trip element is activated, causing the contact of the circuit breaker to open and isolating the circuit. The thermal element is a bimetallic strip that acts as a heat sink. When the temperature of the element exceeds a set limit, the contacts within the unit are tripped, preventing any further current flow.

The unit also features a remote trip unit. This feature allows direct tripping of the breaker from a remote location, such as a control panel or an emergency switch. This feature eliminates the need for manual tripping, and can be indispensable in an emergency situation.

Safety Features

The IELHK111-33660-1-V is constructed with a number of safety features to protect its user from potential electrical hazards. The unit is designed with an automatic reset feature that ensures the breaker will trip and automatically restore the circuit when the electrical overload is corrected. Additionally, the unit has several redundant, reset-preventing components, which detect and halt any overreaching electrical currents before they reach dangerous levels.

The unit is equipped with an alarm system, which will sound a continuous beep whenever the breaker is tripped by an overload. This alarm is designed to alert those in the vicinity of the breaker, informing them that the unit has tripped and that corrective measures must be taken. This feature helps to prevent costly accidents from occurring in domestic and industrial applications.

Conclusion

The IELHK111-33660-1-V is a single-pole, air-insulated, three-pole breaker that is widely used in both industrial and domestic environments. The unit is designed with multiple safety features to protect users from hazardous electrical conditions, as well as an alarm to alert those in the vicinity of a tripped breaker. The unit is capable of automatically switching on and off the circuit whenever the current level exceeds a certain pre-determined value, and is easily reset from a remote location. Overall, the IELHK111-33660-1-V is a reliable and cost-effective option for protection of low voltage AC circuits.
