B-LINE C445MA-2P4A – Frequently Asked Questions
1) What motor current range does the C445MA-2P4A measure module cover?
The C445MA-2P4A measure module covers an overload range of 0.3 to 2.4 amps, so it suits small motor loads. If your motor's full load amps sit above 2.4A, you need a higher-range measure module in the C445 family instead, since the current transformer window in this unit is sized for the 0.3-2.4A band.
2) Can I use this C445 module on a variable frequency drive output?
Frequency rating on the C445MA-2P4A is 20 to 80 Hz, so it reads correctly across standard 50/60 Hz mains and a VFD operating inside that window. Drive output below 20 Hz or above 80 Hz falls outside what this measure module is rated to sense.
3) Does this C445 module do motor thermistor protection as well as overload?
It handles current, voltage, and PTC thermistor input. That means you can wire the motor's embedded PTC sensors straight into the module for direct winding temperature protection alongside the current-based overload function, instead of adding a separate thermistor relay.
4) Is the C445 measure module a complete overload relay on its own?
The C445MA-2P4A is the measure module portion of the C445 electronic overload relay system. It does the sensing (current, voltage, PTC) and pairs with a C445 control module to provide the logic and output contacts, so order both halves for a working overload relay.
5) What torque should I use on the C445 measure module terminals?
Terminal torque is 0.4 Nm, or 3.5 lb-in. That is a low value, so use a calibrated driver rather than a standard screwdriver, especially on control wiring where over-torquing damages the terminal.
6) Is the C445MA-2P4A a standard or an enhanced feature module?
This is the standard feature version of the 45mm C445 measure module, MPN C445MA-2P4A. If your application needs the expanded measurement or diagnostic feature set, you want a different C445 measure module rather than this one.
