Single Phase, 120 VAC, 15 Amp, 1800W

Product Description: ISPA-120-1P-15A

Shift Controls ISPA temperature control panels feature advanced PID temperature control with industry leading safety, construction quality, and control system integration. Power is controlled by a zero-cross SSR for precise temperature control. All enclosures include a disconnecting fuse holder, front mount SAFE/RUN control switch, and a safety contactor to positively disconnect the heater from power when in the SAFE switch position, an over-temperature alarm state, or a thermocouple fault condition.

Seamlessly integrate your control system with a 4-20mA temperature retransmit, user programmable alarm contacts, RS-485 Modbus, and optional external interlock. The NEMA 4X corrosion resistant enclosure is ideal for your most demanding industrial and laboratory environments.

The temperature control panel power connections can be configured from the factory with line and load screw terminals, 5 foot long cords and NEMA 5-15 plug and receptacle, or 12 foot cords with an integrated GFI NEMA 5-15 plug and receptacle. The integrated GFI plug should be used where the heater may be exposed to moisture or water.

Shift Controls is committed to producing a product where safety is paramount. We realize safety directly corresponds to meticulous design, selecting the highest quality components, and demanding perfection in construction.
A two-position RUN/SAFE selector switch allows an operator to place the temperature control panel in SAFE mode when not in use. This de-energizes the safety contactor and places the controller in a STOP mode.
Power is physically disconnected from the heater by an electromechanical contactor when the following occurs:
• The SAFE/RUN Switch is placed in the SAFE position
• An over-temperature condition occurs (PV > ALARM Temp)
• A sensor fault occurs (ex. thermocouple becomes disconnected)
• The optional external interlock relay is de-energized
This feature ensures power is disconnected from the heater to protect personnel and equipment during a fault, over-temperature condition or when not in use.
All panels feature current-limiting fusing which comply with main branch power distribution requirements. The current-limiting specification limits the energy released during an over-current condition and allows the panel to be rated with an industry leading Short Circuit Current Rating (SCCR) of 100 kA.
The interior of the panel is designed and constructed to be fully finger-safe (IP2X) which can reduce the risk of accidental contact with energized parts during OSHA and NFPA 70E allowable energized work.
All components are manufactured by industry leading name brands and are UL Listed or UL Recognized. The panel design complies with or exceeds UL508A and NEC Electrical Codes. All wires and terminal blocks are clearly labeled and numbered according to the included detailed wiring diagrams. Control wiring is separated from the main power wiring, through fuse protection, reducing risk to the user and connected systems. 
Shift Controls understands having the right options available reduces installation time and costs. We are committed to providing your temperature control panel with the options you need for easy installation, commissioning, and operation.

Below are the factory available options, feel free to contact our technical team for any other option or configuration. We will be happy to provide a customized solution for you.
Internal DIN Mount Screw Terminal Blocks - Line and Load (Standard) Line and load wiring is connected to the panel by screw terminal blocks. This option provides the greatest flexibility in either conduit or corded installations.
15 Amp Power Cord (Optional) Line and load wiring, connected from the factory, using a heavy duty power cord. 5 foot plug and 5 foot receptacle cord length.
15 Amp GFI Power Cord (Optional) Line and load wiring, connected from the factory, using a heavy duty power cord with integral GFI outlet. 12 foot plug and 12 foot receptacle cord length.
Add the ability to remotely enable and disable the temperature control panel. When the Enable/Interlock Relay coil is energized, the safety power contactor is energized and the controller is put into RUN Mode.
