Floor Mount
Floor-mounted enclosures are provided as standard for 25–400 hp CT and 30–500 hp VT
@ 460 Vac drives, and for 10–40 hp CT and 15–50 hp VT @ 208/230 Vac drives. The floor-mounted
enclosures are available in five sizes.
Products up to 75 hp CT and 100 hp VT are available in two enclosure sizes as follows with all standard
options, including integrated full speed bypass, and Type 1 and Type 12 designs to meet application
requirements:
• 460 V, 30–50 hp VT and 25–40 hp CT; and 208/230 V, 15–25 hp VT and 15–20 hp CT in Enclosure
Size E (20 in. wide enclosure)
• 460 V, 60–100 hp VT and 50–75 hp CT; and 208/230 V, 30–50 hp VT and 25–40 hp CT in Enclosure
Size F (25 in. wide enclosure)
The 125–500 hp VT@ 460 Vac drives are available in three standard enclosure widths as follows:
• 460 V, 125 hp VT in a 25 in. wide enclosure
• 460 V, 150–250 hp VT in a 30 in. wide enclosure
• 460 V, 300–500 hp VT in a 35 in. wide enclosure
• Consult Drives Product Support for CT ratings above 75 hp.
Full speed bypass and the harmonic filter option require an additional 20 inches added to the standard
enclosure width at the left side. Enclosures for drives above 100 hp are available in Type 1 and
Type 1G designs with filters (fan and door gaskets) to meet application requirements.
Barriered
Barriered enclosures provide a compartmentalized AC drive and bypass solution by separating isolation
and bypass contactors for the AC drive in separate compartments with disconnects for each motor
controller. This provides maximum physical isolation between the two separate motor controllers, and
provides maximum user flexibility when servicing a drive while remaining on bypass.
The floor-mounted barriered enclosures are available in three widths:
• 460 V, 1–25 hp VT and 1–20 hp CT; and 208/230 V, 1–10 hp VT and 1–10 hp CT in a 20 in. wide
enclosure.
• 460 V, 30–50 hp VT and 25–40 hp CT; and 208/230 V, 15–25 hp VT and 15–20 hp CT in a 25 in. wide
enclosure.
• 460 V, 60–100 hp VT and 50–75 hp CT; and 208/230 V, 30–50 hp VT and 25–40 hp CT in a 30 in.
wide enclosure.
For 125 hp drives and higher, an additional 25 inches is added to the enclosure width at the right side.
