Circuit breakers are designed to protect electrical systems against potential damage caused by overloading, short circuits, and other potential faults. The 3C40UL circuit breaker is a type of trip device that is designed to provide protection against overcurrent conditions in low-voltage electrical systems.

The 3C40UL circuit breaker is a UL approved general purpose circuit breaker with a thermal-magnetic trip mechanism. It includes a trip-free mechanism for continuous protection against short circuit and overload conditions. The 3C40UL is rated for a maximum voltage of 277V AC and a maximum current of 40A. Its rated short-circuit capacity is 10kA at 240V.

The 3C40UL is designed for use in a wide range of applications, from lighting control and motor control to emergency lighting systems and emergency stop systems. It can be used in residential, commercial, and industrial environments. The 3C40UL is usually used in single- or three-phase systems.

The working principle of the 3C40UL circuit breaker is straightforward. When an overcurrent flows through the circuit, the circuit breaker trips, interrupting the power flow. This prevents the circuit from being overloaded and prevents any potential damage to connected components due to excessive current flow. The 3C40UL circuit breaker is designed to trip at its rated current of 40A, but will also trip at higher current levels due to its thermal-magnetic trip mechanism.

The 3C40UL circuit breaker is designed for use with Type THQL circuit breakers and meets the requirements of the UL 1077 Standard. It features a highly visible trip indicator and manual reset button for easy operation. The 3C40UL also features a quick-make, quick-break contact system for reliable operation and a compact design for easy installation.

The 3C40UL circuit breaker is an essential component of any electrical system, providing essential protection against overloads, short circuits, and other potential faults. It is designed for a variety of applications and features a reliable trip mechanism and safety features to ensure proper protection.
