Note:
* Derating may be required for higher values.
** Rated speed of the motor varies depending on motor size as shown in the Performance Data table.
National Motors' NMCM series consists of motors designed for fire pump applications as specified in NFPA 20 (Standard for the Installation of Stationary Pumps for Fire Protection). They are certified by UL as per the requirements of UL 1004-5 'Standard for Fire Pump Motors'. These three phase horizontal low-voltage squirrel-cage medium induction motors are constructed and manufactured as per the requirements of NEMA MG 1 standard Design B.
With Open Drip Proof enclosures, they provide best possible ventilation suitable for environments having minimal airborne contaminants and better cooling that contribute to the most efficient performance available from these motors.
