Siemens SIRIUS 3ZY1212-2DA00 Device Connector Link Module for 3RV2/3RT2, 3-Pole, 690V, 40A

For panel builders who want to cut assembly time without sacrificing reliability, the Siemens 3ZY1212-2DA00 device connector replaces traditional point-to-point wiring between SIRIUS 3RV2 circuit breakers and 3RT2 contactors with a single plug-in link module. This direct connection eliminates individual wire preparation, reduces the chance of wiring errors, and keeps the control cabinet layout clean and compact. The module is designed for 3-pole, 3-phase circuits up to 690 V AC and 40 A, making it suitable for motor starters, feeder circuits, and other industrial switching applications.

Highlights

• Direct plug-in link between SIRIUS 3RV2 circuit breakers and 3RT2 contactors
• Frame size S00/S0, 3-pole, rated up to 690 V AC and 40 A
• Reduces wiring effort and speeds up assembly
• Robust insulating plastic housing with copper contacts
• Complies with IEC 60947, UL, and CSA standards

In daily use

Installation is straightforward: mount the circuit breaker and contactor side by side on a DIN rail, then snap the 3ZY1212-2DA00 between them. The mechanical and electrical connection is established instantly, with no need for separate jumpers or terminal blocks. The module's IP20 terminal protection and pollution degree 3 rating ensure dependable performance in typical industrial environments. It can be mounted in any position, giving you flexibility in cabinet layout. The grey/black housing blends with other SIRIUS components, maintaining a professional appearance.
