Instrument transformers and sensors
Type CMF-S
High-accuracy current transformer
Product features
600 V indoor or outdoor, 10 kV BIL, 60 Hertz
Primary amperes: 600 and 1000
Secondary amperes: 5
Rating factor:
2.0 for B-0.5
3.0 for B-0.2 (for 600:5)
Class: meets 0.15% accuracy from 1% through rating factor
Available with primary bar and without primary bar
Application
The CMF-S transformer is used with watt-hour meters, with
or without thermal demand attachments. Applicable to single
or polyphase low voltage circuits, a single 600:5 ratio unit, for
example, will meter at 0.15% accuracy from 6 A - 1200 A for
extended range metering.
The CMF-S is part of ABB’s AccuRange
®
current transformer
portfolio, transformers that reduce inventory requirements
and significantly improve metering accuracy. These units are
especially important for metering installations with large variable
loads in commercial and industrial applications.
Construction features/insulation
The urethane insulating material is permanently molded
to the core and coil assembly, resulting in a compact unit with
improved mechanical, thermal, and dielectric characteristics.
Secondary terminals and cover
Large compression-type secondary terminals are supplied with
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 a short
circuit device to ensure proper installation. Terminals 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.
Extended range metering
AccuRange current transformers deliver high accuracy and sta-
ble 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.
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 ac-
commodate 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.
Test reports
Test reports are stored electronically and can be e-mailed in
various formats at the time of shipment.
Standards
This unit can be tested to all applicable IEEE, CSA, or IEC stan-
dards as requested. This unit is tested in accordance with IEEE
C57.13.6-2005 for high accuracy instrument transformers.
