Power switch with thermal-magnetic trip unit DPX3 160 3P 125A 36KA 420086

Power circuit breaker DPX3 – reliable installation protection

The DPX3 power circuit breaker is an advanced solution designed to protect electrical circuits. It provides effective protection against overloads and short circuits, guaranteeing safety and reliable operation of the installation. The device's design, based on a thermal-magnetic trip unit, allows for precise response to various disturbances, minimizing the risk of damage and downtime. It is a solid element that will work well in both commercial and industrial installations.

Characteristics and application

The DPX3 160A, three-pole (3P) circuit breaker with a short-circuit breaking capacity of 36kA at 400V is ideal for protecting circuits with high loads. Designed for mounting on a TH rail, it offers flexibility in installation configuration. The adjustable overload trip unit range from 100A to 125A allows you to adapt the operating characteristics to the specifics of the protected circuit. An additional undervoltage release increases system safety, protecting against the effects of voltage drops. An integrated trip indicator facilitates quick identification of the device status and location of any problems.

Advantages and design features

• High short-circuit breaking capacity (36kA): ensures effective protection even in the event of serious failures.
• Adjustable overload trip unit range (100-125A): allows precise adjustment to the circuit load.
• Three-pole design (3P): ideal for protecting three-phase electrical installations.
• TH rail mounting: simplifies and speeds up installation and device replacement.
• Trip indicator: allows quick identification of the circuit breaker status and the cause of its operation.
• Screw connection type: ensures a secure and durable connection of wires.
• Protection degree IP30: protects against contact and the ingress of solid objects larger than 2.5 mm – suitable for most indoor environments.
• Possibility of mounting additional auxiliary contacts: expands the functionality of the device, enabling status signaling or remote control.
• Integrated undervoltage release: additional protection against the effects of voltage drops in the network.

This circuit breaker is not only a protective element, but also a convenient tool for the installer – easy mounting on a TH rail and the possibility of expanding functionality make working with it efficient and pleasant. For the end user, this means above all safety and confidence in the operation of the electrical installation for many years.
