Siemens 5SY4306-5

The SUPPLEMENTARY PROTECTOR is designed as a 3-pole, 6 Amp device suitable for AC applications with a voltage rating of 480 VAC. It adheres to UL1077 standards and is classified as an IEC Mini Circuit Breaker with a trip characteristic of Curve A. The dimensions of the unit are compact, measuring 54mm in width and 70mm in depth, facilitating its integration into various control systems.

With a rated short-circuit breaking capacity of 10 kA at 230 V and 35 kA at 400 V, this breaker ensures reliable protection for electrical circuits. The device operates effectively in environments with an ambient temperature range down to -40 °C, making it versatile for demanding applications. It has an IP20 degree of protection, indicating suitability for indoor use where it is shielded from solid objects greater than 12mm.

This supplementary protector also supports a rated insulation voltage of 440 V, with a pollution degree rating of 3, and accommodates a connectable conductor cross-section of 0.75 mm² for both solid-core and multi-wired connections. For installation, it does not support flush-mounted setups and is not explosion-proof. The UL File E116386 in Vol. 1 Sec. 2 ensures compliance with relevant safety standards.
