Features That Make MC Series Fire Features That Make MC Series Fire Pump Controllers a Smart ChoicePump Controllers a Smart Choice
No field Programming LED’s and SPDT contacts for visual
and remote monitoring of alarms Vertically mounted ISO SW and CB Digital display readout Single phase protection Independent pressure and alarm
recorder DC Shunt trip

MC Features ContinuedMC Features Continued Restart Time Delay
Controllers utilize a re-start timer to delay the
instantaneous re-start of the controller. This allows
electromagnetic fields in the motor to decay.

MC Features ContinuedMC Features Continued 35% Voltage Drop
Model MCP
Controllers will continue to operate if
the voltage drops by as much as 35% of rated voltage. This can be critical when starting
the fire pump on emergency power.

MC Features ContinuedMC Features Continued DC Shunt Trip
Controllers use a DC shunt trip coil
powered from all 3 phases. The locked rotor protector will
still operate under a single phase
condition.
