Product description and technical parameters:	Model: 90° : BST-80 BST-670 BST-60 BST-680 BST-780 BST-560 BST-50 Accuracy: class 1.5 Specification: 0.1A 0.5A 1A 5A 10A 15A 20A 25A 30A 40A 50A 60A 75A 100A There’re two standard methods for 10A-10KA use external current transformer with secondary current 1A and 5A. Notes: For 60A 75A 100A meters,when these meters directly connected to circuit,their accuracy is class 2.5. Changeable scale: All scales with printing technique. The dial plate with different scale, which is at the same internal value,can be changeable.But the accuracy is unchangeable. Case: Non-combustile ABS plastic material is used for making external case Mounting: the maximum mounting depth is 43 mm.
