Circuit breaker S 302 2P B 50A 6000A TX3 403392

Overcurrent circuit breaker S 302 2P B 50A is a key element for protecting electrical installations, protecting against the effects of overloads and short circuits. This model, with a rated current of 50A and B characteristic, finds application in both home and commercial installations. The two-pole design provides comprehensive circuit protection.

Features and application

The S 302 TX³ circuit breaker is distinguished primarily by its ease of assembly and connection. The bottom latch and terminal covers significantly simplify installation work. The ability to cooperate with additional equipment, such as auxiliary contacts or releases, expands the functionality of the circuit breaker and allows it to be adapted to the specific needs of the installation. The use of the B characteristic means that the circuit breaker reacts quickly to current increases, but is resistant to short-term surges, which is important when connecting devices with electric motors.

Parameters and performance

This two-pole circuit breaker is designed to operate in circuits with a rated voltage of 400V AC and an impulse voltage of 4kV. Its short-circuit capacity is 6kA at 400V and 10kA at 230V, which guarantees effective protection in the event of a short circuit. A width of 2 modules allows for efficient use of space in the switchgear cabinet. The degree of protection IP20 provides basic protection against contact and ingress of solid objects. Made of high-quality materials, the circuit breaker is characterized by mechanical durability of 20,000 cycles and electrical – 4000 switching cycles. Mounting is done on a TH35 rail.

• Short-circuit capacity: 6 kA (IEC/EN 60898-1) / 10 kA (IEC/EN 60947-2) – high effectiveness in the event of a failure.
• B characteristic: fast reaction to current increase, resistance to short-term surges – ideal for protecting circuits with inductive loads.
• Mounting on TH35 rail: standard solution facilitating installation and replacement.
• Expandability: compatibility with auxiliary equipment – flexibility to adapt to installation needs.
• Rated voltage: 400 V AC – wide application in various types of electrical installations.
• Degree of protection IP20: basic protection against contact and ingress of solid objects - safety of use.
