Power switch 3P, 65kA, TM EB2 250/3H 250A 3P 004672132

Three-pole power circuit breaker with a rated current of 250A provides reliable protection for electrical installations. The device is designed for switching circuits and protecting against the effects of overloads and short circuits, both in domestic and industrial applications. The rated short-circuit breaking capacity of 65kA at 400V guarantees effective protection even in the event of high surge currents.

Characteristics and application

The EB2 250/3H circuit breaker is a compact, fixed-mounted device designed to work with various types of wires and cables. It is intended for protecting power supply installations, motors and electrical equipment. The adjustable setting range of the overload release (157.5…250A) and short-circuit release (1500…2500A) allows for precise adjustment to the specifics of the protected installation. This makes the device perfect for both new installations and modernization of existing ones. The possibility of mounting additional accessories, such as motor drives or auxiliary contacts, expands the functionality of the circuit breaker and allows integration with remote control and monitoring systems.

Construction and product features

The circuit breaker has three poles and is equipped with a rocker button for manual switching on and off. The connection of the main contacts is made using screw connections, which ensures a secure and durable electrical connection. The housing with a degree of protection IP20 protects against accidental contact, and the trip indicator informs about the operation of the protection. The device is characterized by high quality workmanship and compliance with the PN-EN 60947-2 standard, which confirms its safety and reliability. Additionally, the possibility of using a motor drive (optional) facilitates remote control of the circuit breaker, which is particularly useful in automatic energy management systems.

This power circuit breaker stands out for the possibility of adjusting the thermal and electromagnetic protection current, which allows for precise adaptation to the load characteristics. This ensures optimal protection of the electrical installation against the effects of overloads and short circuits. The design of the device allows for easy mounting of additional accessories, and the solid construction guarantees long-term and trouble-free operation. The trip indicator facilitates quick identification of the cause of the protection operation, which reduces the downtime of the installation. The use of high-quality materials ensures resistance to environmental conditions and ensures stable operation in various industrial and commercial applications.
