Easypact CVS250F Circuit Breaker – Reliable Installation Protection

Easypact CVS250F circuit breaker is a 4-pole power circuit breaker with a TMD250A thermal-magnetic trip unit, designed to protect electrical circuits. This device combines high-quality workmanship with an affordable price, offering effective protection against overloads and short circuits. It is an ideal solution for both professional installers and end-users looking for reliable protection of electrical installations in residential and commercial buildings.

Construction and Application

The CVS250F circuit breaker has been designed for easy installation and intuitive operation. Its solid construction ensures long-lasting and trouble-free operation. Designed for DIN rail mounting, it allows for quick integration with existing electrical systems. The rated continuous current of 250A makes it suitable for protecting circuits with higher loads. High short-circuit breaking capacity (36kA at 400V) guarantees the safety of the installation in the event of a failure.

Key Features and Benefits

• High short-circuit breaking capacity: 36kA at 400V provides effective protection of the installation against the effects of short circuits.
• Adjustable thermal-magnetic trip unit: Allows you to adapt the circuit breaker characteristics to the specific needs of the installation, ensuring optimal selectivity and minimizing the risk of unnecessary circuit tripping.
• Limitation of short-circuit currents: Thanks to a special design of the main contacts, the circuit breaker limits short-circuit currents, which increases the durability and extends the life of the device and protects other elements of the installation.
• Versatility: Suitable for use in various types of electrical installations – from residential buildings to commercial facilities.
• Simple installation: The design intended for easy mounting on a DIN rail facilitates and speeds up the installation process.
• Trip indicator: Allows for quick identification of the circuit breaker status – whether it has tripped due to overload or short circuit.
• Safety: Provides effective protection against overload and short circuit – like most circuit breakers in this class.
• Durability: Made of high-quality materials, guarantees long-lasting and trouble-free operation.

Technical Parameters in Practice

The rated continuous current of 250A allows for the protection of circuits with higher power consumption, which is particularly important when powering devices with high energy demand. The setting range of the overload (0-250A) and short-circuit (0-2500A) trip units provides great flexibility in adapting the protection to specific installation requirements. The degree of protection IP40 provides protection against access to hazardous live parts inside the device and against the ingress of solid objects with a diameter greater than 1mm – which is important in industrial environments or exposed to contamination. Power losses of 18.75 W are typical for this type of device and do not significantly affect the energy efficiency of the system.
