Rated for \u003cstrong\u003e30 Amps FLA\u003c\/strong\u003e with a \u003cstrong\u003e24V AC coil secondary\u003c\/strong\u003e, this component is a drop-in replacement for failed contactors in \u003cstrong\u003eLiebert Challenger\u003c\/strong\u003e, \u003cstrong\u003eDeluxe System\/3\u003c\/strong\u003e, and \u003cstrong\u003eDataMate\u003c\/strong\u003e precision air conditioning units. The unit features built-in \u003cstrong\u003eauxiliary contacts (NO\/NC)\u003c\/strong\u003e, allowing for immediate feedback loops to the system logic controller for status monitoring or interlocking. Engineered for inductive loads, its heavy-duty silver cadmium oxide contacts resist welding and pitting, ensuring long-term conductivity even under the high-inrush current demands of scroll compressors and blower motors.

If the \u003cstrong\u003e123273P1S\u003c\/strong\u003e chatter is audible, check the control voltage under load to ensure the transformer provides sufficient VA.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use this to replace a single-pole or two-pole contactor?\u003c\/strong\u003e\u003cbr\u003e\nWhile a \u003cstrong\u003e3-pole contactor\u003c\/strong\u003e can technically interrupt fewer phases, it is specifically designed for 3-phase machinery. Always match the FLA (Full Load Amps) and coil voltage to the original equipment manufacturer (OEM) specifications to avoid premature failure.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I wire the auxiliary contacts?\u003c\/strong\u003e\u003cbr\u003e\nThe auxiliary terminals are side-mounted. The \u003cstrong\u003eNO contact\u003c\/strong\u003e is typically used for \"Run\" confirmation to the microprocessor, while the \u003cstrong\u003eNC contact\u003c\/strong\u003e can be used for lockout or alarm circuits when the contactor is de-energized.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
