SZ201-B16 circuit breaker, 1P, B characteristic, 16A, 6kA, AC 2CDS251025R1165

Overcurrent circuit breaker – reliable protection for electrical installations

This single-pole circuit breaker from ABB's SZ200 series is a key safety component in any electrical installation. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. It is characterized by fast operation and high reliability, which translates into safe use. This device is designed for use in both residential and commercial applications.

The circuit breaker has a B characteristic, which means it is particularly well suited for protecting circuits with receivers with high inrush current – for example, electric motors or devices with heating elements. This avoids unnecessary tripping of the protection during normal operation of these devices. The rated short-circuit breaking capacity of 6kA guarantees safe disconnection of the circuit in the event of a serious failure.

Construction and technical parameters

The SZ201-B16 circuit breaker is mounted on a DIN rail, which facilitates its installation and replacement. Its compact size (1 module wide) allows for efficient use of space in the distribution board. The housing made of high-quality materials ensures durability and resistance to mechanical damage. It is designed to operate at temperatures from -25°C to 55°C, making it a universal solution for various environmental conditions.

The rated insulation voltage Ui is 440V AC, and the rated impulse withstand voltage Uimp is 4kV, confirming its high resistance to overvoltages. It accepts solid wire cross-sections from 0.75 mm² to 35 mm² and stranded wires from 0.75 mm² to 25 mm², ensuring compatibility with various types of installations. Energy limitation class 3 and overvoltage category III indicate a high level of protection against the effects of atmospheric and internal overvoltages. The device meets the requirements of EN 60898-1, which guarantees its safety and compliance with applicable regulations.
