C Family of Solid State Contactors --
The new standard for industrially hardened, solid state contactors

Features

  • 2 switching channels for up to 100 amps per leg
  • Two independent channels OR install it as a 2 pole contactor
  • SMALL -- only 80 mm by 175mm (~3x7 inches)
  • Maximum Surge Survival™ technology -- triple layer, voltage surge protection
  • Thermally optimized heat sink permits edge-to-edge installations
  • Universal installation bracket -- din rail or bolt on
  • REAL POWER switching channels every 1.6 inches
  • Fast, easy replacement for mercury contactors -- same size, same wiring
 
  • Heater contactor, lighting contactor, or motor starter
  • Modular design for flexibility in stocking, installing, and maintaining
  • Green LEDs for input status
  • Built-in snubber circuit and MOVs
  • Built in temperature monitor and temperature shutdown
  • Precise zero crossing switching -- lowest EMI, lowest noise to nearby electronics
  • 4000 volt isolation, 1400 volt blocking voltage, 1650 max amperage for one sinewave
  • Industry standard L1, T1, L2, T2, A1, A2, B1, B2 terminal numbers
  • High density design permits more amps per square inch of installation area

Part Number Line Voltage Range (VAC) Load Current Range (A RMS) Min Control Voltage & Current Draw Max Control Voltage & Current Draw
CZ2H-IAC2 24-575 .25-100 per channel 100VAC/7mA 280VAC/13.3mA
AC activated control inputs typically do NOT need a burden resistor when activated by a triac output controller or triac output PLC.
Off-State dv/dt >3000 v/µs
Isolation 4000 volts isolation: Line to control input 1; Line to control input 2, Line to base
I²T fuse 100A or less, for example: Bussman FWP-100A22F, or smaller. High inrush loads, motors, incandescent lights, stadium lighting may be able to use higher I²T fuses, under certain circumstances. Contact Power-io before using any I²T fuse greater than 100 amps.
Turn-on time One sinewave max, max imbalance delay 1/2 sinewave
Turn-off time One sinewave max, max imbalance delay 1/2 sinewave
Power terminals Will accept #8- #2 AWG wire. Torque: 40-50 inch lbs.
Control terminals Will accept #24- #12 AWG wire. Torque: 3-6 inch lbs.
