Siemens 3-Pole Contactor, 400V AC, 25A - SIRIUS Innovation Series - 3RT2026-1BB40
This 3-pole contactor from Siemens is a reliable way to power an electric motor. Its long service life of 10 million mechanical cycles ensures reliable, long-lasting performance. It features a fuse link to protect it from damage in the event of a short circuit and for added flexibility, it accommodates up to two auxiliary contact blocks. Thanks to slim dimensions of 85 (height) x 45 (width) x 107mm (depth), this is a good choice for installation in areas with limited space. Contactors like this are used to control motor units in heating and cooling equipment.
• Wide operating temperature range of -25°C to +60°C for use in demanding environments
• Low power loss of 1.6W for efficient operation
• IP20 (ingress protection) rating means it's touch-proof and protected against objects larger than 12mm in size
• Can be rotated by 180° on a vertical surface for flexible installation
