Circuit breakers are effective devices used in electrical systems to protect people and property from unexpected short-circuits and overloads. The REX12-TA2-107-DC24V-3A/3A is a double-pole circuit breaker designed to be used in low voltage industrial, commercial and residential circuits.

The REX12-TA2-107-DC24V-3A/3A is designed to protect both phases of a 240 VDC three phase circuit, with a current rating of 3A per pole. This circuit breaker also has an adjustable tripping point, which ensures that the circuit will trip on a current overload of just 1.15 times its rated amperage.

The REX12-TA2-107-DC24V-3A/3A is suitable for use in areas where nearby faults or surges may cause a dead short and for applications requiring a long current holding time up to 500 ms. This circuit breaker is also suitable for many critical, safety or high reliability applications, such as medical or hazardous environment applications.

The main applications for the REX12-TA2-107-DC24V-3A/3A include motor protection, pump protection, low voltage switchgear and appliance protection. This circuit breaker features an integrated control system and can be used to control the overload and short-circuit protection of its load. It also provides an optimal protection against power surges, overcharge and undercharge.

The REX12-TA2-107-DC24V-3A/3A is designed with a special panel system that enables convenient wiring. The unit is supplied with a trip lever mechanism and manual reset button, and it has an additional external reset connection point which can be used to control the reset of the breaker. It also has a mechanical trip indicator which indicates when the breaker has tripped due to an electrical overload.

The REX12-TA2-107-DC24V-3A/3A is designed to work on a thermal-magnetic principle. The thermal trip unit works with a bimetallic element whose resistance increases as temperature rises due to the current about to cause an overload. When this temperature reaches a trip set point, the unit trips the breaker. The magnetic trip unit uses a current transformer with one winding carrying the load current and another used as a control winding. As the load current exceeds the rated current, a magnetic field is created in the transformer which then trips the breaker.

In conclusion, the REX12-TA2-107-DC24V-3A/3A is a double-pole circuit breaker designed for use in low voltage industrial, commercial and residential circuits. It is suitable for motor protection, pump protection, low voltage switchgear and appliance protection, and is designed to work on a thermal-magnetic principle. It is supplied with a trip lever mechanism and manual reset button, and it has an external reset connection point which can be used to control the reset of the breaker.
