| Features 25-500 amps, 500Vac max Three or four wire loads Selectable control and firing modes Resistive and inductive loads |
| The TC3000 SCR assembly is a general purpose three phase power controller for all constant resistance or inductive loads up to 500A/500Vac. The TC3000 fires evenly on all phases to match the load to the generator supply. Three wire wye or delta, four wire wye with neutral and six-wire inside delta load configurations can be controlled. Resistive load firing modes include logic firing for action as a solid state contactor, single cycle for special applications, fast cycle for quick acting heaters and slow cycle for large loads. Phase angle firing is available | for inductive loads. Inputs are logic or analog. The TC3000 is phase rotation insensitive. The unit is shrouded in a protective cover with commissioning and diagnostic points available on the front. Protective measures include built-in high speed fuses with optional fuse-fail microswitches, snubbers and varistors and SCR quenching action on any of several operational alarm conditions. Cooling at 100A and up is by fans, with over-temperature shutdowns. It may be used with the model 260 Diagnostic Unit. | ||||
