This document outlines the replacement parts and instruction guide for Siemens Combination Starters, Classes 17, 18, 25, 26, and 32, covering starter sizes 0-4. It serves as a comprehensive resource for understanding the device's components, operational procedures, and maintenance requirements.

Function Description

The Siemens Combination Starter is an integrated electrical control device designed to provide motor starting, stopping, and overload protection within a single enclosure. It combines a disconnect means (either a disconnect switch or a circuit breaker) with a motor starter (contactor and overload relay). This integration simplifies wiring, reduces installation space, and enhances safety by providing a single point of control and disconnection for the motor circuit. The various classes (17, 18, 25, 26, 32) and sizes (0-4) indicate different configurations and capacities, catering to a wide range of motor control applications. The disconnect switch or circuit breaker provides the means to safely isolate the motor circuit from the main power supply for maintenance or emergency situations. The motor starter, comprising a contactor and an overload relay, is responsible for switching the motor on and off and protecting it from excessive current draw that could lead to overheating and damage.

Usage Features

The combination starter is designed for ease of use and robust operation in industrial environments. Key features include:

Integrated Control: By combining the disconnect and motor starter functions, the device offers a streamlined control solution. Operators can manage motor operation and safety from a single point, reducing complexity.
Disconnect Options: Users can select between a disconnect switch (with or without fuse clips) or a circuit breaker as the primary disconnect means. This flexibility allows for tailoring the protection scheme to specific application requirements, such as the need for fuse protection or the convenience of a resettable circuit breaker.
Handle and Mechanism: The device incorporates a robust handle and mechanism for operating the disconnect switch or circuit breaker. This handle provides clear visual indication of the ON/OFF status and often includes features for locking out the power during maintenance, enhancing personnel safety.
Pilot Devices: The starter can be equipped with various pilot devices, such as push buttons (Start-Stop, For-Rev-Stop, High-Low-Stop), selector switches (H-O-A, OFF/ON, For-Off-Rev, High-Off-Low, Keyed H-O-A), and pilot lights (Red "ON," Green "ON," Red "Run," Green "Run," Red "Off," Green "Off," Push-to-Test Red "ON," Push-to-Test Green "ON," Push-to-Test Green "Off," White "Control Power On," Amber "OL Relay Trip Alarm Light"). These devices provide local control and status indication, allowing operators to interact directly with the motor and monitor its operational state.
Control Power Transformers (CPT): For applications requiring different control voltages, the starter can include CPTs of various capacities (45VA, 100VA, 150VA) and voltage configurations (e.g., 208/120V, 480/24V). This ensures that the control circuit operates at the appropriate voltage, independent of the main power supply.
Auxiliary Contacts: The motor starter (contactor) can be fitted with auxiliary contacts (e.g., 1NO, 2NO, 1NC, 2NC, or combinations thereof). These contacts are used for interlocking, signaling, and control circuit integration, allowing the starter to communicate its status to other control systems or to implement complex control logic.
Control Options: Additional control options, such as a disconnect switch interlock (2NO/2NC), a ground lug for 3-conductor wiring, and a 120V coil transient suppressor, further enhance the device's functionality and safety. Control relays (e.g., 2NO & 2NC, 4NO, 4NC) can also be integrated for more advanced control schemes.
Enclosure Types: The starters are available in various enclosure types (e.g., Type 1, 3R, 4, 4X, 12) to suit different environmental conditions, providing protection against dust, moisture, and corrosion.
Overload Relay Reset Operator: An external reset operator for the overload relay allows for convenient resetting of the protection device after an overload condition, minimizing downtime.

Maintenance Features

The design emphasizes ease of maintenance and repair, ensuring long-term reliability and serviceability.

Modular Design: The combination starter is constructed with a modular approach, allowing individual components like the disconnect switch, circuit breaker, handle mechanism, and pilot devices to be replaced independently. This simplifies troubleshooting and reduces the need to replace the entire unit for a single component failure.
Clear Replacement Part Identification: The manual provides detailed tables with catalog numbers for various replacement parts, including disconnect switches, fuse clips, circuit breakers, handle and mechanism assemblies, pilot devices, control power transformers, auxiliary contacts, control options, quarter-turn latches, and overload relay reset operators. This clear identification facilitates quick and accurate ordering of necessary components.
Instructional Diagrams: Step-by-step instructions and diagrams are provided for critical maintenance procedures, such as replacing the disconnect handle and circuit breaker handle. These visual aids guide qualified personnel through the process, ensuring correct installation and adjustment.
Safety Warnings: Prominent "DANGER" and "WARNING" labels are included throughout the manual and on the device itself, highlighting potential hazards such as hazardous voltage and short-circuit explosion risks. These warnings emphasize the importance of de-energizing and grounding the equipment before maintenance, using qualified personnel, and following all safety instructions.
Qualified Personnel Requirement: The manual explicitly states that maintenance should only be performed by "qualified personnel" who are familiar with the equipment, trained in safety practices (energizing/de-energizing, grounding, tagging), proficient in using protective equipment, and capable of rendering first aid. This ensures that maintenance tasks are carried out safely and effectively.
Handle Adjustment and Verification: Instructions for handle replacement include steps to verify proper operation (ON/OFF) and ensure that the door cannot be opened when the handle is in the "ON" position. This confirms that safety interlocks are functioning correctly after maintenance.
Sealing Integrity: During handle reinstallation, instructions emphasize ensuring that the handle housing is sealed against the enclosure flange to prevent moisture entry, maintaining the integrity of the enclosure's environmental protection.
Warranty Information: The manual clarifies that the sales contract contains the entire obligation of Siemens and that any statements in the manual do not create new warranties or modify existing ones, providing clear expectations regarding product support.
