Circuit breaker 4P, 36kA, TM release (magnetic adjustment) EB2 800/4LF 630A 4P 004671118

Reliable circuit protection with power switch EB2 800/4LF

This four-pole power switch with a rated current of 630A is a solid solution for securing electrical installations. Designed for switching circuits and protecting against the effects of overloads and short circuits, it will work well in both industrial applications and public buildings. The rated short-circuit breaking capacity of 36kA guarantees an effective response in emergency situations, minimizing the risk of damage and downtime.

The EB2 switch is versatile – it can be used to protect cables, power cords, motors and electrical equipment. Thanks to the magnetic adjustment (TM), the tripping characteristic can be precisely adapted to the specifics of the protected circuit. This is particularly important when protecting devices with high starting currents, such as motors.

Construction and functionality

The device is based on proven technology, ensuring reliability and long life. The switch has a built-in tripping mechanism with magnetic adjustment, allowing the characteristics to be adapted to the needs of a specific application. The tripping indicator informs about the operation of the protection, making it easier to locate and repair faults. The possibility of mounting a motor drive expands the functionality of the device, enabling remote control.

This switch ensures safe operation of the installation under continuous load thanks to the rated current of 630A. The short-circuit breaking capacity of 36kA at 400V guarantees effective disconnection of the circuit in the event of a short circuit. Magnetic adjustment (TM) allows precise adaptation of the tripping characteristics to the specifics of the protected circuit. Four poles allow protection of three-phase power circuits and neutral circuits. The degree of protection IP20 provides protection against finger contact and ingress of solid objects. The possibility of mounting a motor drive expands the functionality of the device, enabling remote control. Screw connection ensures a secure and durable connection of the power supply cables.

The switch is designed in accordance with PN-EN 60947-2, which confirms its compliance with European safety and quality standards. Installation is simple and intuitive – the device is designed for permanent mounting and offers flexibility in terms of operating position (any). This makes installation quick and easy for professionals, and the device can be used in various environmental conditions (ambient temperature from -25°C to +50°C).
