Siemens 3RH2916-2FA22 Auxiliary Switch Front Mount, 2 NO + 2 NC, Spring-Loaded Terminals Original Brand New

Overview

The Siemens 3RH2916-2FA22 is a high-performance auxiliary switch designed for seamless integration with Siemens 3RT2 power contactors and 3RH2 contactor relays. This essential component is used to expand the control and signaling capabilities of your electrical circuits. Its front-mounting design ensures a simple and space-saving installation, making it ideal for a wide range of industrial applications.

Key Features

• Configuration: 2 Normally Open (NO) + 2 Normally Closed (NC) contacts. This versatile configuration allows for both control circuit signaling and safety interlock functions.
• Mounting: Front-mounted. This design allows for quick and easy installation directly onto the contactor, eliminating the need for additional mounting rails and reducing cabinet space.
• Terminals: Spring-loaded terminals. This advanced terminal technology provides a vibration-proof, gas-tight connection, ensuring reliable operation and reducing maintenance time. No tools are required for wire insertion, which simplifies and speeds up the installation process.
• Current Path: The specific current path configuration is 1 NO, 1 NC, 1 NC, 1 NO, providing clear and predictable circuit behavior.
• Compatibility: Specifically designed for use with Siemens SIRIUS series 3RT2 contactors and 3RH2 contactor relays, guaranteeing perfect mechanical and electrical compatibility.

Benefit

• Enhanced Control: Adds crucial signaling and control functions to your existing contactor setup without the need for a larger or separate device.
• Reliable Performance: The robust design and high-quality materials ensure long-term reliability in demanding industrial environments. The spring-loaded terminals maintain a secure connection even under high vibration.
• Easy Installation: The front-mounting feature and spring-loaded terminals significantly reduce installation time and complexity, leading to lower labor costs.
• Space-Saving: Its compact, front-mounted design helps to optimize cabinet space, which is critical in modern industrial control panels.
• Seamless Integration: As an original Siemens accessory, the 3RH2916-2FA22 ensures perfect compatibility and performance with other Siemens SIRIUS products.

Function

• Signaling: Provides feedback on the contactor’s status (e.g., “contactor is on,” “contactor is off”) to PLCs, indicator lights, or other control devices.
• Interlocking: Used in safety circuits to ensure that certain conditions are met before a main contactor can be energized, preventing hazardous operations.
• Control Circuit Expansion: Expands the number of auxiliary contacts available, allowing for more complex control logic and automation tasks.
