Siemens Solid State Relay 415V AC

The Siemens Solid State Relay (SSR) for 415V AC is a type of solid-state switching device designed for industrial control applications. These relays are used to switch electrical loads without mechanical contacts, offering advantages such as faster switching, higher reliability, and longer life since they have no moving parts.

Key features and description of Siemens SSRs suitable for 415V AC include:

• Solid-state construction with high-efficiency thyristors or semiconductors to handle AC loads up to 415V and higher.

• Compact and space-saving design, often with integrated heat sinks for optimal thermal management.

• Suitable for frequently switching motor and resistive loads in industrial automation and control circuits.

• Various connection options including screw and spring-loaded terminals for secure wiring.

• Operating standards such as IS/IEC 60947, often with CE marking.

• Enables zero-cross switching to reduce electrical noise and transient interference.

• Typically available in single-phase and three-phase versions with rated currents varying by model, some up to 70A.

• Control supply voltages compatible with industrial AC mains (e.g., 230V, 415V) for coil operation.
