Power switch 3P, 50kA, electronic release EB2 400/3E 400A 3P 004671112

Power switch for installation and device protection

This three-pole power switch EB2 400/3E with a rated current of 400A and a short-circuit breaking capacity of 50kA is a reliable solution for protecting electrical circuits. The use of an electronic release ensures a precise and fast response to overloads and short circuits, minimizing the risk of damage and downtime. This switch is used both in industrial installations and in public buildings where high reliability and safety are required.

Design and functionality

The switch is designed for permanent mounting, which ensures stability and reliable operation. It has a trip indicator that makes it easy to identify the device's status. Thanks to the ability to adjust the overload release setting in the range of 160-400A and the short-circuit release (400-4000A for delayed and 2240-5200A for instantaneous), it can be adapted to the specific needs of the installation. The connection of the main contacts is made using screw connections, which guarantees a secure electrical contact. Additionally, an optional motor drive allows for remote control of the switch.

Applications and benefits

The EB2 400/3E switch is perfect for protecting:

• Supply circuits: protects against overloads and short circuits in electrical installations.
• Motors: protects electric motors from the effects of overloads and short circuits, extending their lifespan.
• Electrical equipment: ensures safe operation of electrical devices by quickly disconnecting in the event of a failure.
• Installations with high starting current: its C characteristic allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.

Using this switch translates to:

• High safety: effective protection against overloads and short circuits minimizes the risk of fire and electric shock.
• Reliability: solid construction and precise releases ensure long-lasting and trouble-free operation.
• Flexibility: the ability to adjust settings allows the switch to be adapted to different applications.
• Easy installation: screw connections facilitate installation and connection of wires.
• Compliance with standards: meets the requirements of PN-EN 60947-2 standard, which guarantees safe use.
