Circuit breaker DPX3 160 3P 80A 16kA 420004

Solid protection of the electrical installation with DPX3 160 circuit breaker

The DPX3 160 circuit breaker is a reliable solution for protecting electrical circuits in residential, commercial and industrial buildings. Designed by Legrand, this three-pole circuit breaker with a rated current of 80A and a short-circuit breaking capacity of 16kA provides effective protection against overloads and short circuits. It is a key element of any installation, guaranteeing safety of use and minimizing the risk of failure.

### Functionality and application

The DPX3 160 circuit breaker is designed for mounting on a TH rail, which facilitates its installation and replacement. Its universal rated voltage (220…690 V) allows it to be used in a wide range of installations. The integrated undervoltage release increases safety, and the ability to connect a motor drive expands the functionality of the device. This circuit breaker is used to protect lighting circuits, socket outlets, and devices with higher power consumption.

### Key features and benefits

* **High short-circuit breaking capacity (16kA):** Ensures a quick and effective response in the event of a short circuit, minimizing damage to the installation and equipment.

* **Overload release setting range (64…80A):** Allows precise adjustment to the load characteristics, protecting against overloads and ensuring stable operation of the installation.

* **Three-pole design:** Provides full protection for three-phase electrical circuits.

* **TH rail mounting:** Facilitates quick and easy installation and replacement of the circuit breaker.

* **Integrated undervoltage release:** An additional layer of protection against voltage drops that can damage connected devices.

* **Possibility of mounting a motor drive:** Allows remote control of the circuit breaker, which is particularly useful in building automation systems.

* **Tripping indicator:** Quickly informs about the operation of the circuit breaker, making it easier to diagnose problems in the installation.

* **Screw connection of main contacts:** Ensures a secure and durable connection of electrical wires.

* **Protection degree IP30:** Protection against touching with fingers and against solid objects larger than 2.5 mm – suitable for most standard working conditions.

### Construction and operating parameters

The DPX3 160 circuit breaker is characterized by a solid construction of a permanently mounted device. It has one switching auxiliary contact and one normally open contact, which allows integration with control and signaling systems. The setting range of the delayed short-circuit release is 800…800 A, which ensures appropriate selectivity with other protective elements in the installation. Thanks to this, the device will not operate unnecessarily during short-term voltage surges caused, for example, by the starting of electric motors – characteristic C allows it to react more slowly to short inrush currents. The circuit breaker complies with applicable safety standards, which guarantees its reliability and safety of use.
