Power relay, AC-3, 25 A, 11 kW / 400 V, 4-pole, AC 110 V, 50 Hz, main contacts: 2 normally open + 2 normally closed, auxiliary contacts: 1 normally open + 1 normally closed, screw connection, size: S0. SIRIUS 3RT25 relay for pole switching in hoist motors or for switching two separate loads. The 3RT25 relays are part of the SIRIUS modular system with optimally coordinated products. They impress with high performance while maintaining a compact design and high contact reliability. They can be combined in various ways with other components in the load branch. Many of the device combinations are factory tested. The relays provide optimal connection to the control for every application (parallel, via ASi or IO-Link). Integrated auxiliary contacts reduce the complexity of your setup. The front connections allow for easy wiring. The 3RT25 relays are climate-resistant and globally approved (e.g., IEC and UL/CSA). They are available in various sizes and a wide range of power ratings with AC and DC actuation. In addition to screw connection technology, the devices are also available with spring-loaded terminals for a quick, maintenance-free, and vibration-resistant connection. The comprehensive accessories, such as auxiliary contacts, auxiliary relays, etc., are uniform across all sizes. Simple, efficient, always up to date - the SIRIUS modular system.
