Power switch x250 4P 40kA 100A TM HNB101H

x250 Power Switch – reliable protection for electrical installations

The x250 power switch is a four-pole device designed to protect electrical circuits against overload and short circuit. A rated continuous current of 100A and a high short-circuit breaking capacity of 40kA at 400V guarantee effective protection even in demanding conditions. The device's design allows for flexible mounting – both on a DIN rail (optional) and as a stationary element.

Functionality and application

This switch is used in electrical installations in commercial, industrial and residential buildings where high reliability and safety are required. The TM (thermomagnetic) release characteristic provides an optimal response to various disturbances, protecting against both long-term overloads and sudden current surges. The overload release setting range of 63 to 100A allows for precise adjustment to the load characteristics.

Key features and benefits

• High short-circuit breaking capacity: 40kA at 400V ensures effective protection of the installation in the event of a short circuit.

• Flexible mounting: The ability to mount on a DIN rail or as a stationary device facilitates integration with various electrical systems.

• TM characteristic: Provides optimal protection against overloads and short circuits, minimizing the risk of damage and downtime.

• Wide rated voltage range: From 220 to 415V allows use in different electrical networks.

• Solid construction: The device made of high-quality materials ensures durability and reliable operation.

• Expandability: Optional accessories, such as auxiliary contacts, overcurrent releases or motor drives, allow you to adapt the switch's functionality to specific needs.

• Safety: Equipped with short-circuit protection (included), which further increases the level of installation protection.

• Protection class IP40: Provides protection against access to hazardous live parts and against the ingress of solid objects larger than 1mm.

Design and parameters

The x250 switch has screw connections for wires with a cross-section from 35 to 185 mm², which facilitates assembly and ensures a secure electrical connection. The device is equipped with a switch as a control/operating element and has a built-in fast short-circuit release mechanism (setting range: 600-1300A). The rated insulation voltage is 800V, and the rated impulse voltage is 8kV. The total power loss for the rated current is 24.8W. The switch is characterized by high electrical endurance (1000 cycles) and mechanical endurance (4000 cycles).
