Type HWT equipment is suitable for use on indoor or outdoor primary circuits where kVAR is required. They may be installed at various load centers or directly at the terminals of 2400, 4160 and 4800 volt motors. Units up to 900 kVAR are available. Permissible ambient temperatures are -40°C to +40°C. Discharge resistors included reduce voltage to 50 volts or less within 5 minutes of de-energization.
