Siemens 5SY41046 installatieautomaat 4 A 1P C 6 kA 230/400 V

The Siemens 5SY41046 is a high-quality miniature circuit breaker (MCB) from the 5SY4 series, designed for reliable protection of electrical installations against overloads and short circuits. With a rated current of 4 A and a tripping characteristic of C, it is ideal for protecting circuits with moderate inrush currents, such as lighting and general-purpose loads. This 1-pole breaker operates at 230/400 V AC and offers a rated short-circuit breaking capacity of 6 kA, ensuring safety and compliance with EN 60898-1.

Advantages

Compact 1-module design (18 mm) saves space on DIN rails. Screw terminals allow secure connection of conductors up to 35 mm². Robust construction ensures long mechanical and electrical service life of 10,000 cycles. Suitable for ambient temperatures from -25 °C to +45 °C, making it versatile for various environments.

Suitable for

• Protection of lighting circuits, socket outlets, and small appliances in residential and commercial buildings
• Installation in distribution boards with DIN rail (TH 35 mm) mounting
