Power switch 3P, 36kA, TM EB2 250/3S release 160A 3P 004671081

Power switch – reliable installation protection

This three-pole power switch with a rated current of 160A and a short-circuit breaking capacity of 36kA is a key element of every safe and efficient electrical installation. Designed for both professional and domestic applications, it provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. Equipped with a thermal-magnetic trip unit (TM), it offers flexibility in adapting the characteristics to the specifics of the load.

Functionality and construction

The EB2 250/3S 160A 3p switch is characterized by a solid fixed-mounting construction. Thanks to the screw connection of the main contacts, installation is simple and secure. The trip indicator allows for quick identification of the device status, which facilitates diagnostics and servicing. The IP20 degree of protection provides basic protection against touch and the ingress of solid objects. The possibility of connecting a motor drive expands the functionality of the switch, enabling remote control.

Applications and benefits

This switch is perfect for protecting circuits powering various types of receivers, including:

• Electrical installations in residential and commercial buildings: Ensures the safety of using electrical appliances.
• Electric motors: Protects motors against overloads and short circuits, extending their lifespan.
• Electrical switchboards: Forms an integral part of the switchboard, providing central protection for the installation.
• Electrical apparatus: Protects sensitive equipment from damage caused by power supply irregularities.

It is worth noting the wide adjustment range of the overload trip unit (100.8…160 A) and short-circuit (960…2080 A), which allows for precise adaptation to specific application needs. The rated short-circuit breaking capacity at 36kA at 400V guarantees effective disconnection of the circuit in the event of a serious failure. The possibility of mounting additional accessories, such as derivative trip units or auxiliary contacts, further increases the functionality of the device.
