The Circutor SEC72 300/5 A (code M102YH) is an exchangeable face scale for the EC72 moving iron ammeter, designed for 72 x 72 mm panel modules. It reconfigures or replaces the ammeter dial to display currents measured through a 300/5 A current transformer, giving a full scale reading of 300 A.

Technical specifications:

• Model: SEC72 300/5 A
• Circutor code: M102YH
• EAN: 8433059002824
• Full scale: 300/5 A
• Measurement range: 300/5 A
• Compatible device: EC72
• Panel module size: 72 x 72 mm
• Scale dimensions: 60 x 60 x 1 mm
• Weight: 0.004 kg

Features and benefits:

• Exchangeable design allows an EC72 panel ammeter to be reconfigured for a 300/5 A CT circuit without replacing the complete instrument
• 60 x 60 x 1 mm scale fits precisely within the 72 x 72 mm EC72 module housing
• Minimal weight of 0.004 kg simplifies handling and fitting in the panel
• Belongs to a wide SEC72 scale family covering 5/5 A through 5000/5 A, enabling one ammeter body to serve multiple current ratings across a site

Applications:

• Replacing worn or damaged dials on EC72 ammeters wired to 300/5 A current transformers
• Reconfiguring existing EC72 instruments when a panel circuit is upgraded to a 300 A rating
• LV switchgear and distribution board instrumentation using 300/5 A CT secondary circuits
• Industrial control panels requiring 72 x 72 mm format analogue current indication at 300 A
