Duct Heater Accessories
At the core of every resistive heating solution is its control panel. A poorly designed control panel can be the difference between poor performance, a short product life-span, and unsafe working conditions. Like all Smiths Group plc companies, TUTCO takes this responsibility very seriously. All of our products are built to the highest quality standards and current
electrical codes.
UL labels are important for the following reasons:
- Industrial building inspectors REQUIRE them. Equipment installations can be rejected for not adhering to NEC codes.
- Knowing the equipment and the accessories are built to quality standards and will not interfere with normal operations minimizes troubleshooting assuring peace of mind.
- It’s SAFER. Remember, check the label.
3 Pole Magnetic Contactor
Magnetic contactors are standard in all duct heaters. They are used for primary or back-up control. UL approved for 250,000 cycle operation.
Air Flow Switch
The Air Flow Switch prevents the heater from being energized when the fan is not on and is rated for .05” ± .02” WC to 12”WC.
Electronic Step Controller
An Electronic Step Controller provides smooth sequencing of a duct heater up to 12 steps. Used with a 2-10 VDC T-stat, 4-20mA signal, or 2-10VDC DDC.
Terminal Block
TUTCO Terminal Blocks are sized for high voltage copper conductors up to a 500 MCM line per pole.
Fuses Blocks
TUTCO offers a 3-Position Fuse Block required for NEC code and designed to UL Standards.
Power Fusing
TUTCO provides Power Fusing to UL standards and NEC code required for heaters drawing more than 48 AMPS.
Control Transformers
TUTCO Control Transformers are utilized when the control voltage differs from the incoming line voltage feeds.
Main Power Connector
TUTCO Main Power Connectors are high voltage terminal blocks and sized for copper conductors only. The connector is sized to accept parallel line feeds up to 500 MCM each per pole.
Time Delay Relay
TUTCO Time Delay Relays provide 30 to 60 seconds when energizing or de-energizing the circuit controlled.
