Siemens SIRIUS 3RT2336-1AP60 Contactor 4-Pole AC-1, 60A, 220V AC/240V AC Coil, S2 Size Original Brand New

Overview

The Siemens SIRIUS 3RT2336-1AP60 is a high-performance 4-pole contactor designed for efficient switching of AC-1 (non-inductive or slightly inductive) loads up to 60 Amperes at 400V (at 40°C). Part of the trusted SIRIUS 3RT23 series, this robust S2 size contactor is equipped with a versatile 220V AC (50 Hz) / 240V AC (60 Hz) operating mechanism and features integrated 1 NO (normally open) + 1 NC (normally closed) auxiliary contacts, making it ideal for a wide range of industrial and power distribution applications. Its reliable screw terminals ensure secure and straightforward wiring.

Function & Application

The Siemens 3RT2336-1AP60 contactor is engineered for reliable and efficient switching operations. Its primary functions include:

• Four-pole switching of weak or non-inductive loads (AC-1): Perfect for heating elements, lighting, resistive loads, and general power distribution.
• Disconnecting loads or power generation plants from the grid: Ensures safe isolation during maintenance or emergencies.
• Transfer switching: Facilitates smooth transitions between different power sources.
• Integration into industrial control systems: Acts as a crucial switching element in automation and machinery.

Benefit

• High Reliability: Manufactured to rigorous Siemens standards (IEC 60947-1, IEC 60947-4-1, IEC 60947-5-1), ensuring consistent performance and longevity.
• Versatile Power Switching: Handles significant AC-1 loads, offering flexibility for various applications.
• Integrated Auxiliary Contacts: The 1 NO + 1 NC contacts provide immediate feedback and allow for direct integration into control circuits without needing external auxiliary blocks (for many applications).
• Easy Installation: Screw terminals simplify wiring and connection processes, reducing installation time.
• Robust Protection Features: Designed with considerations for short-circuit, overload, and overvoltage protection, contributing to overall system safety and reliability.
• Compatibility with SIRIUS Ecosystem: Seamlessly integrates with other Siemens SIRIUS components like overload relays (3RU2 thermal, 3RB3 electronic) for comprehensive motor protection.
• Electromagnetic Compatibility (EMC): Fulfills requirements for environment category A, ensuring stable operation in industrial environments.
• Replaceable Coil (3RT233 contactors): Offers increased serviceability and extends product lifespan.

Technical Detail & Standard

• Standard Compliance: IEC 60947-1, IEC 60947-4-1, IEC 60947-5-1 (for auxiliary switches)
• Protection of Connections:
  • Main Connections: Requires suitable short-circuit and overload protection (refer to technical product data sheet or Digital/Configuration Manual for load feeders for device combinations).
  • Auxiliary Connections: Short-circuit and overload protection information available in the technical product data sheet.
  • Control Supply Voltage Connections: Protection must comply with relevant standards for control panel configuration (e.g., suitable power supply with current-limiting function, appropriate miniature or circuit breakers).
• Overvoltage Protection (Control Supply Voltage): Can be retrofitted with surge suppressors (RC elements, varistors, diodes, or diode assemblies – ordered separately as accessories).
  • Note: Damping increases break times of the contactor and delay times of NO/NC contacts. Refer to the Equipment Manual for details on damping influence.
• Connection Methods:
  • Main Circuit: Screw terminals with box terminal. Direct connection with cable lugs possible when box terminal is removed.
  • Auxiliary & Control Circuit: Screw terminals.
• Electromagnetic Compatibility (EMC): Fulfills requirements for environment category A. Observe configuration notes in the Equipment Manual when used with frequency converters.
• Contact Reliability of Auxiliary Contacts: High contact reliability, especially suitable for solid-state circuits ($\ge 1\text{ mA}$ at $\ge 17\text{ V}$). Recommended for voltages $\le 110\text{ V}$ and currents $\le 100\text{ mA}$.
• Motor Protection: Compatible with 3RU2 thermal overload relays or 3RB3 electronic overload relays for overload protection (mount directly onto the contactor).
• Operating Mechanism: Conventional AC operating mechanism. Control via A1-A2 connections.
• Serviceability: Solenoid coil replacement is possible for 3RT233 contactors. Contacts for 3RT233 contactors can also be replaced.
• Auxiliary Contact Expansion: Basic unit contains two integrated auxiliary contacts (1 NO + 1 NC). Can be expanded with additional auxiliary switches (refer to Auxiliary switches, instantaneous → Overview for permissible configurations).
