Its compact design and a versatile 600 V AC, 60 Hz coil voltage make it suitable for various international standards.

Key Benefit

• High Performance: Capable of handling demanding motor control applications with a 95 A rating and 45 kW power capacity.
• Space-Saving Design: The compact S3 frame size allows for efficient panel design and space optimization.
• Versatile Auxiliary Contacts: Features a built-in 1 NO + 1 NC auxiliary contact configuration, simplifying control circuit wiring and reducing the need for external components.
• Reliable Connections: Equipped with secure and durable screw terminals for a strong, vibration-resistant connection.
• Global Compatibility: Designed to meet international standards with its 600 V AC, 60 Hz coil, making it suitable for global use.
• Long Service Life: Part of the SIRIUS modular series known for its high mechanical and electrical endurance, leading to reduced maintenance and downtime.

Function

• Motor Switching: Efficiently and safely switches electric motors ON and OFF.
• Load Control: Suitable for switching various resistive and inductive loads in industrial automation systems.
• Auxiliary Signaling: The integrated auxiliary contacts provide status feedback (NO for “ON,” NC for “OFF”) to the control system or PLC.
• Remote Operation: Can be controlled remotely via a 600V AC signal applied to the coil terminals.
• Overload Protection (when combined with a thermal overload relay): When paired with a suitable SIRIUS overload relay, it forms a complete motor starter for protection against overcurrents.
