The MotorSavers 77C and 777
are electronic overloads designed for single and three phase
motor protection, but are particularly suited to protect pumps
and other equipment which could benefit from the underload protection
offered.
Fully programmable by users, the 77C
and 777 MotorSavers feature adjustable set points for all major
functions.
With in-built current transformers
which eliminate the need for external transformers under 90 amps,
the MotorSavers are easily installed and offer sophisticated
yet reliable protection.
The single phase 77C MotorSaver protects
against:
- Underload
- Overload
- High current
- High voltage
- Low voltage
- Rapid cycling
The three phase 777 MotorSaver protects
against:
- Underload
- Overload
- High current
- High voltage
- Low voltage
- Rapid cycling
- Current unbalance
- Voltage unbalance
- Single phasing
- Reverse phasing
Both units are fitted with RS485 communication
ports (software sold separately) to enable connection to a computer,
allowing operators to control motors, view operating parameters
and record operating parameters to disk in as low as one second
increments. Up to 99 MotorSavers of 77C and/or 777 can be linked
to one computer. |
