Questions Buyers Ask
What is the largest ratio available?
MSQ-125 covers 1000/5 A up to 6000/5 A through a 125 mm window, which is the top of the range.
Can MSQ be used above 720 V?
No. The series is rated for AC circuits with a rated voltage below 720 V. Above that, move to the cast resin range.
Does MSQ suit mine transformer sets?
Yes, the product is stated as suitable to form a complete set of mine transformer.
What is the difference between MSQ-30 and MSQ-30B?
MSQ-30 has a 30 mm round window for cable; MSQ-30B is the busbar variant and starts at 5/5 A.
