• Space-Saving Design: Compact Size S00 footprint optimizes panel space in control cabinets.
• Fast & Secure Wiring: Spring-loaded terminals simplify installation, reduce wiring time, and offer enhanced connection reliability.
• Broad Compatibility: Seamlessly integrates with other SIRIUS components like overload relays for comprehensive motor protection.
• High Contact Reliability: Specially designed auxiliary contacts ensure dependable operation even with low voltages and currents.
• Robust & Standards-Compliant: Manufactured to rigorous IEC standards, guaranteeing quality, safety, and performance.

Standards & Protection

The 3RT2316-2AB00 adheres to stringent international standards, including:

• IEC 60947‑1
• IEC 60947‑4‑1
• IEC 60947‑5‑1 (for auxiliary switches)

Device Connection Protection: All connections must be protected against overload and short circuits. Detailed information for protection of main, auxiliary, and control supply voltage connections can be found in the technical product data sheet and configuration manuals. Recommendations for protection devices like miniature or circuit breakers are available for control circuits.

Overvoltage Protection: The 3RT23 contactors can be retrofitted with surge suppressors (RC elements, varistors, diodes, or diode assemblies) to dampen opening surges in the coil, available as separate accessories.

Connection Methods

• Main Circuit: Features convenient spring-loaded terminals.
• Auxiliary and Control Circuit: Utilizes reliable screw terminals.

Electromagnetic Compatibility (EMC)

The contactor fulfills requirements for environment category A, ensuring stable operation in various electromagnetic environments. For use with frequency converters, consult the Equipment Manual for specific configuration notes.

Contact Reliability of Auxiliary Contacts

For switching voltages $\le$ 110 V and currents $\le$ 100 mA, the auxiliary contacts of 3RT23 contactors are highly reliable, suitable for solid-state circuits with currents $\ge$ 1 mA at voltages of 17 V and higher.

Motor Protection Integration

While the 3RT2316-2AB00 is primarily for AC-1 loads, it can be combined with Siemens 3RU2 thermal overload relays or 3RB3 electronic overload relays for comprehensive protection of connected motors against overload.

Operating Mechanism Types

This version features a conventional AC operating mechanism, controlled via the A1-A2 control supply voltage connection.
