Siemens Miniature Circuit Breaker 1-Pole 40A Type B 230V AC 60V DC 10 kA Breaking Capacity 5SY4540-6

Siemens 5SY4540-6 Miniature Circuit Breaker is a high-quality, reliable 1-Pole breaker rated for 40A current with Type B tripping characteristics. It is designed to protect electrical circuits in industrial, residential, and functional construction sectors. The device operates at 230V AC and withstands up to 60V DC voltages with a breaking capacity of 10 kA, ensuring excellent circuit safety and performance.

The breaker features a DIN rail mount for easy installation and removal, making system maintenance efficient and fast. Its toggle switch actuator allows straightforward resetting after tripping events. The breaker complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077 standards, ensuring compliance with major international safety regulations and enhancing system reliability.

With an IP20 rating, this Miniature Circuit Breaker protects against solid objects larger than 12 mm while providing safe electrical isolation. The compact dimensions of 90mm height, 90mm depth, and 76mm width make it adaptable to a wide range of electrical panels and setups. Manufactured in Germany, the breaker represents top-tier engineering quality and durability.

This Siemens 5SY4 series model supports various supplementary components like control current switches, fault signal contacts, shunt releases, under voltage releases, and remote operating mechanisms. It can also be combined with RCCB units for added protection against electric shock and fire hazards.

Its Type B tripping characteristic makes it suitable for protection of home and light industrial circuits by tripping between 3 to 5 times the rated current. Additionally, Siemens provides information on other tripping curves: Curve C (5 to 10 times the rated current) for general applications and Curve D (10 to 14 times) for high surge loads such as welders and motors.

The circuit breaker has an automatic cut-out feature and supports 1 to 4-pole configurations within the 5SY4 series. Ideal for use in electrical distribution systems demanding reliable overload and short-circuit protection.

Its screw terminal ensures secure wiring connections for stable electrical performance. This product endorses Siemens' Better World initiative focusing on sustainability and extended product life.
