This document describes the Siemens Remotely Operated Transfer Switching Equipment (RTSE), also known as a Fernbetätigter Netzumschalter (RTSE), Matériel de connexion de transfert à distance (RTSE), Equipo de transferencia operado remotamente (RTSE), Commutatore di rete con controllo remoto (RTSE), Chave de transferência telecomandada (RTSE), Uzaktan çalıştırılan transfer anahtarlama ekipmanı (RTSE), Коммутационная аппаратура дистанционного переключения (RTSE), Zdalnie sterowany przełącznik sieciowy (RTSE), or 远程电源切换装置 (RTSE). The specific models covered are 3KC3424-2AA22-0AA3, 3KC3426-2AA22-0AA3, 3KC3428-2AA22-0AA3, 3KC3430-2AA22-0AA3, 3KC3432-2AA22-0AA3, and 3KC3434-2AA22-0AA3, which comply with IEC 60947-1, IEC 60947-3, and IEC 60947-6-1 standards.

Function Description:

The Siemens RTSE is designed for the remote switching of power sources, ensuring a reliable and safe transfer between different supplies. It can operate in both automatic and manual modes, providing flexibility for various applications. The device manages the main power supply and control inputs, facilitating the selection of power sources and operational logic. It supports dual power supply configurations, which can enhance reliability, although the use of a Dual Power Supply (DPS) module is not strictly mandatory. When a DPS is not used, both supply 1 and supply 2 must be connected to the power supply, and appropriate short-circuit protection (fuses) must be installed. The RTSE can be integrated into a DIN rail system (IEC 60715) for easy mounting.

Important Technical Specifications:

Rated Impulse Withstand Voltage (Uimp):
- Power circuit: 6 kV
- Motor unit/Control circuit: 4 kV
- For applications where overvoltages exceeding 4 kV may occur, external surge arresters are required to limit these overvoltages to a maximum of 4 kV.
Main Power Supply Connections:
- Wire cross-section: 10 ... 70 mm² (Cu)
- Tightening torque for main terminals: 5.0 Nm (M6 screws, >10 mm length)
- The device requires both power supply systems to be connected in phase.
- All terminals, even unused ones, must be tightened.
Control Power Supply and Control Inputs:
- Voltage: 220 V AC -20% (176 V AC) to 240 V AC +20% (288 V AC), 45 ... 65 Hz.
- Current: Up to 3 A (for 0.5 ... 2.5 mm² wire cross-section).
- Wire Cross-Section (Control Inputs):
  - Solid: 0.5 ... 2.5 mm²
  - Stranded: 0.5 ... 1.5 mm²
- Tightening Torque (Control Inputs): 0.5 Nm (for 0.5 x 3 mm screws).
- Terminal Designations:
  - 101/102: Supply I
  - 201/202: Supply II
  - 313: Position O order (closed with 317). Allows selection of continuous operation logic (always closed) or impulse logic.
  - 314: Position II order (closed with 317).
  - 315: Position I order (closed with 317).
  - 317: Common control terminal for 313 to 315.
- Terminals 313, 314, and 315 should not be connected to any power supply.
Auxiliary Contacts (3KC9603-1, 3KC9603-2):
- Voltage/Current Rating: 250 V AC / 2 A / AC-13; 24 V DC / 2 A / DC-13.
- Wire Cross-Section:
  - 0.5 ... 2.5 mm²
  - 0.5 ... 1.5 mm²
- Tightening Torque: 1 Nm (PZ2 screws).
Auxiliary Conductor Terminal (3KC9622-2):
- Voltage: Ue = 415 V AC / 240 V AC, Uimp = 2.5 kV.
- Current: Ie = 12 A.
- Wire Cross-Section: 0.5 ... 1.5 mm².
- Tightening Torque: 0.5 Nm (for 0.5 x 3 mm screws).
Autotransformer (3KC9624-1):
- Voltage: Ue = 400/230 V AC, Uimp = 2.5 kV.
- Wire Cross-Section: 0.5 ... 2.5 mm² or 0.5 ... 1.5 mm².
- Tightening Torque: 0.45 Nm (for 0.5 x 3 mm screws).
Bridging Bar (3KC9618-2 for 40-125 A, 3KC9618-3 for 160 A):
- Tightening torque: 5.0 Nm.

Usage Features:

Remote Mode: The device supports remote operation, allowing for automated transfer switching based on predefined logic.
Manual Operation: In addition to remote control, the RTSE can be operated manually for emergency or maintenance situations. This involves using a tool to switch between positions I, O, and II. The maximum torque for manual operation is 8.0 Nm.
Padlocking Mode: The device can be padlocked in positions I, O, or II to prevent unauthorized operation during maintenance or other critical situations. This feature enhances safety by physically securing the switch position.
Operational Logic: The control inputs (313, 314, 315) allow for selection between impulse logic (momentary contact) and continuous operation logic (maintained contact).
Dual Power Supply (DPS) Module (3KC9625-1): This optional module provides enhanced reliability by managing two independent power supplies for the control electronics. If the DPS is not used, the control electronics must be powered from both supply 1 and supply 2, and appropriate fuses (3NW6003-1, 3NW7013) must be installed to ensure short-circuit proof wiring.
Accessories: The RTSE supports various accessories, including auxiliary contacts (3KC9603-1, 3KC9603-2), auxiliary conductor terminals (3KC9622-2), autotransformers (3KC9624-1), bridging bars (3KC9618-2, 3KC9618-3), sealing ribbons (3KC9621-2), and terminal covers (3KC9604-2, 3KC9621-2).

Maintenance Features:

Safety First: All installation and maintenance work must be performed by qualified personnel. Before working on the device, all power sources must be turned off and locked out to prevent accidental re-energization. All covers must be replaced before restoring power.
Sealing: For safety, only plastic seals (3KC9621-2) should be used for sealing the device. Metallic seals can pose a risk of electric shock in case of a fault.
Terminal Covers: Terminal covers (3KC9604-2, 3KC9621-2) are available as an option to protect against accidental contact with live parts.
Regular Inspection: Ensure all terminals are tightened correctly, even if not in use, to maintain proper electrical connections and prevent damage.
Overvoltage Protection: If the device is used in an environment prone to overvoltages exceeding 4 kV, external surge arresters must be installed to protect the device from damage.
