3RT2017-2FB42
The Siemens SIRIUS 3RT2017-2FB42 features a 24V DC coil and one set of normally closed (NC) auxiliary contacts. It has the same body specifications as the 2FB41 and is suitable for interlocking or power failure feedback circuit designs.
Product Positioning
The 3RT2017-2FB42 shares the same chassis and 24V DC coil specifications as the 2FB41, differing only in the auxiliary contact type—this product features one set of NC (normally closed) instantaneous contacts, and the main circuit AC-3 is also a 12A, 5.5kW S00 frame contactor at 400V. The coil also has a built-in suppression diode, and the spring-loaded terminal design facilitates quick and easy wiring, making it suitable for motor control circuits requiring normally closed interlock signals.
Core Product Advantages and Features
1 set of NC interlock auxiliary contacts
Normally closed instantaneous contacts are suitable for control circuits that require power failure feedback, interlock protection, or "reverse" signal logic.
24V DC coil, built-in suppression diode
It uses the same coil specifications as 2FB41, ensuring stable operation and reducing surge interference to the control circuit during power outages.
S00 Miniaturized Body
It shares the same body size and mounting hole positions as other contactors in the same series, which facilitates unified panel planning and spare parts interchange management.
Spring-loaded terminal quick-connect
Both the main circuit and auxiliary circuits are screwless, making field wiring and regular maintenance more efficient.
