Circuit breaker S 301 1P B 16A 6000A TX3 403357

Reliable protection for electrical installations – Legrand S 301 circuit breaker

This single-pole circuit breaker from the S 301 series, with a rated current of 16A and a B characteristic, is a key element in protecting electrical installations in residential, commercial and industrial buildings. Designed by the renowned Legrand company, it guarantees safety and durability. This circuit breaker effectively protects circuits against the effects of overloads and short circuits, ensuring uninterrupted power supply and minimizing the risk of failure.

Functionality and application

The S 301 TX³ circuit breaker is distinguished by its easy installation thanks to the bottom clip and terminal covers. The ability to cooperate with various auxiliary equipment – such as auxiliary contacts, signaling devices, undervoltage releases or remote drives – expands its functionality and allows it to be adapted to individual installation needs. The B characteristic makes this circuit breaker ideal for protecting circuits with low starting currents, typical of lighting or sockets. The rated short-circuit breaking capacity of 6kA (at 230V and 400V) provides effective protection in the event of a short circuit.

Key features and benefits

• Wide application: Ideal for protecting circuits in home, commercial and industrial installations.

• Easy installation: Bottom clip and terminal covers facilitate installation and connection of wires.

• Compatibility: Compatible with a wide range of DX³ series auxiliary equipment.

• High reliability: A product from the renowned Legrand company, guaranteeing long-lasting and trouble-free operation.

• Compact dimensions: A width of only 1 module makes it easy to install in switchboards with limited space.

• Safety: Provides effective protection against overloads and short circuits, minimizing the risk of fire or equipment damage.

• Compliance with standards: Meets safety standards, confirming its high quality.

Technical parameters in practice

The S 301 circuit breaker is characterized by a rated voltage of 230/400V AC and a rated impulse withstand voltage of 4kV. The IP20 degree of protection provides protection against finger contact and against the ingress of solid objects larger than 12.5 mm. The energy limitation class is 3, which means high resistance to short-circuit energy. Mounting is on a TH35 rail, which is standard in most electrical switchboards. It is worth remembering to choose the correct tripping characteristic (B) for the type of load – the B characteristic is recommended for loads with low starting currents.
