The Circutor SEC72 150/5 A (code M102YE) is an exchangeable scale plate for EC72 and EMSC series moving iron panel ammeters, calibrated for a 150/5 A current transformer ratio. Designed for 72 72 mm panel instruments, it fits directly into the existing meter to update or replace the displayed measurement range. The scale measures 60 60 1 mm and weighs just 8 g.

Technical specifications:

• Model: SEC72 150/5 A
• Circutor code: M102YE
• EAN: 8433059002749
• Measurement range: 150/5 A
• Full scale: 150/5 A
• Compatible device: EC72
• Panel module size: 72 72 mm
• Scale dimensions: 60 60 1 mm
• Weight: 0.008 kg

Features and benefits:

• Exchangeable design means the scale can be swapped without replacing the entire ammeter, lowering maintenance cost
• Calibrated specifically for the 150/5 A CT ratio, ensuring correct primary current readings on the instrument face
• Compact 60 60 1 mm profile fits precisely within EC72 moving iron instruments without any modification
• Lightweight at 8 g, adding negligible load to the panel instrument
• Part of the SEC72 series spanning CT ratios from 5/5 A to 5000/5 A, making like-for-like or range-change replacements straightforward

Applications:

• Replacing worn or damaged scales in Circutor EC72 moving iron panel ammeters
• Reconfiguring an existing EC72 ammeter to show a 150/5 A CT measurement range
• Industrial switchboard and control panel builds using 72 72 mm format instrumentation
• Electrical distribution boards where a 5 A CT secondary is used with a 150 A primary conductor
