Circuit breaker S 302 2P B 13A 6000A TX3 403386

Overcurrent circuit breaker S 302 2P B 13A is a reliable element protecting the electrical installation against the effects of overloads and short circuits. Designed for both domestic and professional applications, it ensures safety of use and long-term protection of circuits. The two-pole design allows disconnecting two phases simultaneously, which increases the effectiveness of protection.

Features and application

This circuit breaker, characterized by B characteristic, is particularly recommended for protecting lighting and socket circuits, where loads of a resistive or slightly inductive nature occur. The B characteristic means that the circuit breaker reacts quickly to an increase in short-circuit current, but is less sensitive to short-term current surges during device start-up. The rated current of 13A makes it ideal for protecting standard circuits in residential and commercial buildings. Mounting is done on a TH35 rail, which facilitates and speeds up installation.

Parameters and benefits

• Short-circuit capacity reaches 6 kA at 400 V AC and 10 kA at 230 V AC – ensures effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage to the installation and equipment.

• Rated voltage is 400 V AC – allows use in most standard electrical installations.

• B characteristic provides a quick response to overloads and short circuits, protecting devices from damage.

• Flush mounting increases the aesthetics of the installation and saves space.

• Width of 2 modules allows for optimal use of space in the switchgear cabinet.

• Degree of protection IP20 provides protection against finger contact and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside switchgear cabinets.

• Rated impulse withstand voltage Uimp is 4 kV – resistance to surge voltages, which increases reliability in difficult conditions.

Circuit breakers from the TX³ series are characterized by compatibility with a wide range of auxiliary accessories (auxiliary contacts, signaling contacts, release devices), which allows adapting their functionality to individual installation needs. Solid construction and high quality workmanship guarantee long-term and trouble-free operation. Execution in gray RAL 7035 color provides an aesthetic appearance and easy identification in the switchgear cabinet.
