Overview
This document provides detailed technical specifications, dimensions, accessories, and operational parameters for a series of base-mounted changeover switches compliant with IEC 60947-3 standards. The switches are available in multiple sizes and current ratings, with options for 3-pole (3P) and 3-pole plus neutral (3P+N) configurations. 4-pole (4P) versions are also available upon request.
Product Range and Sizes
- Size 0: Rated currents 125A, 160A, 200A
- Size 1: Rated currents 250A, 315A, 400A
- Size 2: Rated currents 500A, 630A, 800A
- Size 3: Rated currents 1000A, 1250A
- Size 4: Rated currents 1600A, 1800A, 2000A
- Size 5: Rated currents 2000A, 2500A, 3150A
Electrical Ratings and Performance
Each size category specifies the following key electrical parameters:
- Rated Thermal Current (Ith): Ranges from 125A to 3150A depending on size.
- Rated Breaking Capacity (400V AC22 or AC23): Varies from 375A to 9450A peak breaking current.
- Rated Making Capacity (400V AC22 or AC23): Up to 10000A for larger sizes.
- Short-Circuit Making Capacity (Icm): Peak values from 13kA to 100kA depending on size.
- Short-Time Withstand Current (Icw): Typically 7kA to 50kA rms for 1 second.
- Rated Insulation Voltage (Ui): 1000V across all sizes.
- Rated Impulse Withstand Voltage (Uimp): 8kV to 12kV depending on size.
- Operational Current (Ie) at 400V: Specified for utilization categories AC21A, AC22A, and AC23A.
Mechanical and Operational Characteristics
- Number of Mechanical Operations: Typically 3000 to 8000 cycles depending on size and model.
- Maximum Weight: Ranges from approximately 1.8 kg for smaller sizes to over 42 kg for the largest models.
- Terminal and Mounting Dimensions: Detailed dimensions provided for shaft lengths, shaft extensions, mounting holes, and terminal sizes.
Accessories and Options
- Handles: Direct handles and external handles with shafts are available, including IP65 rated external handles.
- Safety Key Lock Devices: Simple and double key lock options for handle locking in OFF or ON positions, with key removal only when locked.
- Auxiliary Contacts: Available in configurations 1NO+1NC and 2NO+2NC, rated for 16A resistive and 4A inductive loads at 250Vac.
- Terminal Shrouds and Phase Barriers: Various kits for terminal protection and phase segregation, noting some accessories are incompatible with each other.
- Bridging Links: Provided for linking poles, with codes specified per size.
- Shaft Extensions: Multiple shaft extension types and lengths available for different sizes.
Installation and Mounting
- Detailed door drilling dimensions for external handle and key lock device installation are provided for each size.
- Standard shafts are included with each switch; extensions can be ordered separately.
Special Versions
- Versions without an OFF (0) position are available under the S5D series designation; consultation is required for these models.
- 4-pole versions are available on request.
Standards Compliance
All changeover switches comply with IEC 60947-3 standards, ensuring safety, reliability, and compatibility with industrial electrical systems.
Critical Parameters and Limitations
- Short-circuit making capacity tests assume no limiting protective device and short-circuit duration maintained between 50 ms and 100 ms.
- Operational current ratings are specified for 50/60 Hz frequency; other voltages or utilization categories require consultation.
- Some accessories are not compatible with each other and must be selected accordingly.
Summary
This document serves as a comprehensive technical reference for selecting, installing, and accessorizing a wide range of motorized base-mounted changeover switches. It covers electrical and mechanical specifications, accessory options, and installation guidelines for sizes ranging from 125A to 3150A, ensuring suitability for various industrial applications requiring reliable switching and isolation.
