Description
Firetrol FTA990 Disconnecting Devices provide a UL Listed means of disconnecting and isolating the fire pump controller from the incoming power source. The FTA990 gives overcurrent protection coordination upstream of the fire pump controller.
Overcurrent Protection Characteristics:
- The protective device shall NOT open with 2 minutes at 600% of the full load current of the fire pump motor(s).
- The protective device shall NOT open with a re-start transient of 24 times the full load current of the fire pump motor(s).
- The protective device shall NOT open within 10 minutes at 300% of the full load current of the fire pump motor(s).
- into for circuit breaker shall NOT adjustable.
Features
The following are included as standard with each controller:
- Suitable for use as service equipment
- NEMA Type 2 (IP22) Enclosure
- Flange mounted disconnect handle lockable in the “ON” position
Applications
The FTA990 shall be specifically designed to assure complete upstream overcurrent protection coordination with the electric fire pump controller. A flange mounted disconnect handle lockable in the closed (ON) position shall be standard.
Specifications
disconnecting means shall be a model FTA990, manufactured by Firetrol, Inc. The unit shall be factory assembled and tested. The FTA990 shall be specifically designed to assure complete upstream overcurrent protection co- ordination with the electric fire pump controller.
