LELHK11-35545-20-V Circuit Protection

Circuit Breakers

A circuit breaker is an automatic electrical switch which provides protection from possibly dangerous overcurrent circumstances such as short circuits or electrical malfunctions. Circuit breakers operate by sensing a change in current flow, typically an increase, and interrupting the current flow before dangerous levels are reached. This interruption of current in an electrical circuit prevents a fire, electric shock, and other potential harm which would result from prolonged overload situations.

LELHK11-35545-20-V Application Field and Working Principle

The LELHK11-35545-20-V isolator device is a low-voltage device designed for most residential and commercial applications. It is used to switch, protect, and monitor circuits in the event of dangerous current, such as short circuits or power surges. The isolator has a rated voltage of 480V and a working voltage of 460V. Its rated current is 630A and its short-circuit capacity is 35kA. This device is used in a variety of residential and commercial applications, including air-conditioning, lighting circuits, and other low-voltage applications.

The isolator device is very simple in its operation. When the circuit load current reaches a critical level, the device will sense the overload current and trip, cutting off the power. Once the overload condition is removed, the isolator will either manually reset (if an override with a manual reset is included) or automatically reset itself once the power level is within the safe range. This automated resetting feature ensures that the device can be quickly restored to its operating position after any overcurrent condition has been removed.

The LELHK11-35545-20-V is tested to be in compliance with the most recent IEC and UL standards. Included among these standards are UL 489-Circuit Breakers and UL 1564-Fuses and Surge Protective Devices. This ensures that the device is reliable, stable, and safe for use in both residential and commercial applications. When properly installed and operated, the LELHK11-35545-20-V isolator device offers reliable protection from dangerous overcurrent conditions.
