Overcurrent circuit breaker, 2P, Z characteristic, 2A, 25kA, AC | S302P-Z2 2CDS382001R0278

Protection of installations and devices – ABB S302P-Z2 circuit breaker

This two-pole circuit breaker from ABB with Z characteristic is a reliable protection for your electrical installation. Designed to protect circuits against the effects of overloads and short circuits, it ensures safe operation and minimizes the risk of failure. The Z characteristic means that this circuit breaker reacts very quickly to current increases, which is particularly important when protecting circuits with devices with high inrush current, e.g. motors.

Construction and application

The S302P-Z2 circuit breaker is designed for mounting on a TH35 rail, which facilitates its installation in electrical switchboards. Its compact dimensions – 2 module width – allow for efficient use of space in the switchboard cabinet. Designed to operate in AC/DC networks, with a rated voltage of 415V and a frequency of 50-60Hz, it will work in a wide range of applications – both in residential and commercial buildings. The rated short-circuit breaking capacity of 25kA (at 400V) guarantees effective protection even in the event of serious disturbances in the network.

Key features and benefits

• Z characteristic: Fast response to current increase, ideal for protecting circuits with motors and other devices with high inrush current.
• Rated short-circuit breaking capacity 25kA: High resistance to overvoltage and short circuits, ensuring installation safety.
• Compact dimensions (2 modules): Saving space in the switchboard.
• Versatility: Can be used in AC/DC networks.
• Wire cross-section 0.75 - 25 mm²: Compatibility with different types of wires.
• Protection degree IP20: Protection against touching with fingers and solid objects larger than 12.5 mm.
• Rated impulse withstand voltage Uimp 6kV: Resistance to impulse overvoltages.
• Power loss at 4.2W: Energy efficiency of the device.

This circuit breaker complies with IEC 60947-2 and EN 60898 standards, which confirms its high quality and safety of use. Installation is simple and intuitive, which will be appreciated by both professional installers and people performing electrical work independently (while taking all necessary precautions). The solid construction guarantees long-term and trouble-free operation of the device.
