Application
The CMF-S transformer is primarily used with watthour meters, with or without thermal demand attachments, and is applicable to single or polyphase low voltage circuits.
Extended range metering
AccuRange current transformers deliver high accuracy and stable performance over a wide load swing, making them a great fit for variable load applications. Accuracy is guaranteed to be 0.15% from 1% of nominal current through rating factor. These units deliver savings through improved accuracy metering and reduced inventory.
Construction and insulation
The insulating material is permanently molded to the core and coil assembly, resulting in a compact unit with improved mechanical, thermal, and dielectric characteristics.
Primary
The CMF-S has a 3.06" primary opening suited for circuits requiring more than one cable lead. The large opening can accommodate the conductors required for full current capacity, even at high rating factors. The opening is large enough to accommodate four 500 MCM or three 750 MCM insulated cables. A removable primary bar can be supplied with either a slot hole or 4-hole NEMA pattern.
Secondary terminals and cover
The CMF-S is supplied with embedded compression-type secondary terminals, a short circuit device, and a clear, rectangular snap-on cover suitable for locking with a meter seal. This clear plastic cover allows a visual check of connections and is keyed to ensure the shorting clip is across the terminals when no wires are connected. This safety feature avoids dangerous voltages across the secondary terminals if the primary is energized. Terminals accommodate #14-6 wire and can also serve as a post-type connector by looping wire under the screw head.
Base
The base is constructed of corrosion-resistant aluminum and secured to the encapsulated base support by four symmetrically located screws.
Test reports
Test reports are stored electronically and can be e-mailed in various formats at the time of shipment.
Standards
This unit meets or exceeds all requirements of IEEE C57.13-2016 and can be tested to other standards as requested
