Siemens SENTRON 5SY7 MCB, 3+N, 3A Curve C, 400V AC, 72V DC, 5 kA Breaking Capacity | 5SY7603-7

Description

The Siemens 5SY7603-7 SENTRON is a premium 3+Neutral miniature circuit breaker (MCB) designed to offer comprehensive protection for single-phase circuits. With a 3A rating and a Curve C tripping characteristic, it is suitable for applications involving inductive loads with moderate inrush currents. This MCB operates at 400V AC and 72V DC, and its 5 kA breaking capacity ensures safe interruption of fault currents across all four poles (3 live and 1 neutral). The Siemens 5SY7603-7 provides robust protection.

This Siemens MCB is engineered for reliability and performance, featuring a robust construction that makes it suitable for installation in control panels and distribution boards. The 3+Neutral design ensures that both the live conductors and the neutral conductor are disconnected simultaneously during a fault condition, which is critical for safety, especially in IT and TN-S earthing systems. The Siemens 5SY7603-7 is designed for comprehensive safety.

Applications for the Siemens 5SY7603-7 include the protection of lighting circuits, socket outlets, and circuits supplying appliances with moderate starting currents in residential, commercial, and light industrial settings. Its Curve C characteristic offers a balance between sensitivity to overcurrents and tolerance for inrush currents. The simultaneous switching of the neutral conductor by the Siemens 5SY7603-7 enhances safety protocols.

When requiring thorough protection for single-phase circuits, particularly those with a neutral conductor, the Siemens 5SY7603-7 SENTRON MCB is an excellent choice. Its 3A rating, Curve C characteristic, and 3+Neutral configuration provide reliable and safe circuit protection. Trust in Siemens for premium quality and dependable performance in your electrical installations.
