Make it Simple with Cooper Bussmann resettable three-phase remote fuse monitor that integrates with a Programmable Logic Controller (PLC) or other monitoring and control equipment.
Specifications:
• Power Input: 24Vdc / 5mA
• Sensing Voltage: 600V/30mA
• Output Signals: Digital 0Vdc (Low), 24Vdc (High)
- 0Vdc Low – Fuse is good
- 24Vdc High – Fuse has opened
When the fuse opens, the output signal is sent high and will remain high until the unit is reset
• Rated Impulse Voltage: 8kV
• Local Indication: Two distinct LEDs indicate unit power (green) and open fuse (red). Upon the replacement of the fuse, the actuation of the reset switch will reset the open fuse LED
• Flammability Rating: UL 94V0
Wiring:
• For power, signal and ground connections use 22-24AWG (0.25mm2) 300V rated wire
Emissions and Immunity Testing:
• Electrostatic Discharge IEC 61000-4-2
• Electrical Fast Transient/Burst IEC 6100-4-4
• Surge Immunity IEC61000-4-5
Packaging:
• The CH-PLC is packaged individually
• A single unit monitors up to three phases
• Package includes 0.11” (2.8mm) quick connects for power, signal and ground connections
Minimum Circuit Voltage:
• Minimum circuit voltage required across the CH holder is 100Vac for the remote indication device to operate Installation Technique:
• Mounts on the left side of the fuse holder and mechanically interlocks with the fuse holder switch handle with hardware provided
IP20 Rating: Yes
Environmental Data:
• Storage and Operating Temperature: -20°C to 75°C
Agency Information:
• UL 508
• cULus to CSA Standard 22.2 No.14
PLC Programming:
• The CH-PLC signal line is designed to provide a digital input to a PLC I/O card.
• Programmable Logic Control program must be written to properly interpret the input signal to the PLC.
• The PLC program should check for consecutive high signals before taking action on a critical process.
De-energize all circuits before installing or removing any CH-PLC devices and follow all prescribed safety procedures.
Comb Bus Bar & Power Feed Accessories
Make Installation Easier
• Distributes power in single- or three-phase configurations
• Cut-to-length solution does not compromise finger-safe protection
• Single-phase bus bars rated to 1000Vdc and 100A in end-fed configuration (200A for center-fed configuration)
• Three-phase bus bars rated to 600Vac/dc and 100A in end-fed configuration (200A for center-fed configuration)
• Power feed terminals for single-phase and three-phase service
