Recently we were delighted to discover a lot of comments about our 4-pole switch in a forum. The opinions were very positive, so we have summarized the most important facts and answers here:
KA63B.T904.VE2.F437 manual transfer switch for safe and easy switching between two power supply systems (e.g. from mains to backup power such as gensets, photovoltaics):
• enables direct disconnection under load
• 4 pole
• up to 63 A
• Simple top-hat rail mounting
• including space-saving pole bridge
• Mains changeover switch in accordance with IEC 60947-6-1
• Diverter switch according to IEC 60947-3-1
• also with shaft extension, blocking device or as enclosure variant
• with leading/trailing neutral conductor - helps to avoid voltage peaks during switching operations, for example
• Large connection cross-sections up to 25 or 16 mm²
• Large contact opening distances - improved disconnector function
