Circuit breaker, B characteristic, 6 kA, 63 A, 1P SZ201-B63 2CDS251025R0635

Protection of installations and devices – reliable ABB STANDARD series circuit breaker

This single-pole ABB STANDARD series circuit breaker, with B characteristic and a rated current of 63A, is a key safety element in every electrical installation. It provides effective protection against the effects of overloads and short circuits, protecting both wires and connected devices. Its compact size (1 module width) allows for easy mounting in a distribution box.

This circuit breaker is characterized by a high short-circuit breaking capacity of 6kA at 230V and 400V, which guarantees its reliable operation even in difficult conditions. The B characteristic means that the circuit breaker reacts quickly to current increase, but is more tolerant to short-term current surges than circuit breakers with a C characteristic – which is particularly important when protecting circuits with receivers with high inrush current, e.g. motors.

Installation and application – for professionals and end users

The circuit breaker is designed for mounting on a TH35 rail. The cross-section of the connected wires can range from 0.75 mm² to 35 mm² for solid wires and from 0.75 mm² to 25 mm² for stranded wires, providing flexibility in choosing the appropriate cables. Thanks to the IP20 degree of protection, it is resistant to touch and contamination, which increases safety of use. The rated impulse withstand voltage of 4kV provides additional protection against overvoltages.

This model is used to protect lighting circuits, socket circuits and other electrical circuits in residential and commercial buildings. It is ideal for installations requiring a quick response to overloads, while minimizing the risk of unnecessary circuit tripping due to short-term current surges. Energy limitation class 3 and surge category III confirm its high quality and compliance with applicable safety standards.
