Overcurrent circuit breaker S 302 2P C 16A 6000A TX3 403528

Overcurrent circuit breaker from the S 300 TX³ series provides reliable protection of electrical installations against the effects of overloads and short circuits. Model S 302, two-pole, with a rated current of 16A and C characteristic, is perfect for both home and commercial installations. The design with a bottom latch and terminal covers facilitates mounting and connection of wires.

Functionality and Application

This circuit breaker, designed by Legrand, provides effective protection of electrical circuits. The C characteristic means that the circuit breaker reacts with a certain delay to short-term current surges – which is particularly important when connecting devices with motors or other elements generating inrush current. The rated short-circuit breaking capacity of 6kA at 400V and 10kA at 230V guarantees safety in the event of a failure. Two-pole (2P) design ensures disconnection of both the phase and neutral conductor if necessary.

Mounting and Compatibility

The S 302 TX³ circuit breaker is designed for mounting on a TH35 rail. Its width of 2 modules allows for efficient use of space in the distribution board. The ability to work with additional equipment – such as auxiliary contacts or releases – increases functionality and adaptation to specific installation needs. The IP20 protection class indicates protection against touching with a finger and solid objects with a diameter of more than 12.5 mm.

The short-circuit capacity of the circuit breaker reaches 6 kA at a voltage of 400 V and 10 kA at a voltage of 230 V, which guarantees effective disconnection of the circuit in the event of a short circuit. Thanks to the C characteristic, the circuit breaker is particularly recommended for circuits with receivers generating surge currents, such as motors. Mounting on a standard TH35 rail facilitates installation in electrical distribution boards. Two-pole design (2P) ensures disconnection of both the phase and neutral conductor if necessary. The possibility of expansion through compatibility with additional equipment, such as auxiliary contacts or releases, increases the functionality of the device. High insulation voltage of 500 V ensures resistance to insulation breakdown. Energy limitation class 3 provides adequate protection against the effects of electric arc.
