Built with advanced Electronic Potential Relay (EPR) technology, this unit allows technicians to \"dial in\" an exact \u003cstrong\u003epickup voltage\u003c\/strong\u003e between 130V and 370V. As a direct \u003cstrong\u003e90-71 replacement\u003c\/strong\u003e, it simplifies service calls by consolidated stock, functioning as a wire-to-wire universal solution for virtually all 3-terminal and 5-terminal potential relays. The 30A normally closed contacts are rated for \u003cstrong\u003eHVACR compressors\u003c\/strong\u003e up to 5 HP, operating reliably across a 110-270 VAC range.\u003c\/p\u003e\n\n\u003cp\u003eEngineered for professional \u003cstrong\u003eHVAC troubleshooting\u003c\/strong\u003e, the \u003cstrong\u003eSupco APR5\u003c\/strong\u003e features a safety time-out mechanism (1.0 to 1.5 seconds) that protects the \u003cstrong\u003estart winding\u003c\/strong\u003e and prevents the \u003cstrong\u003estart capacitor\u003c\/strong\u003e from venting if the motor fails to turn over. Its non-positional mounting design and universal bracket ensure a seamless fit in any orientation, making it a staple for \u003cstrong\u003ecompressor relay replacement\u003c\/strong\u003e. This relay recycles instantly, providing immediate restart capabilities crucial for maintaining system uptime in critical cooling setups.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Serves as a \u003cstrong\u003euniversal potential relay\u003c\/strong\u003e replacing \u003cstrong\u003e90-71\u003c\/strong\u003e and other industry-standard models.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Pickup Voltage:\u003c\/strong\u003e Precisely set limits between 130V and 370V to match specific compressor requirements.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnhanced Protection:\u003c\/strong\u003e Integrated 1.5-second safety cutout prevents \u003cstrong\u003emotor winding\u003c\/strong\u003e damage during locked rotor conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible Installation:\u003c\/strong\u003e Non-positional mounting with screw or push-on terminals for fast field replacement.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh Capacity:\u003c\/strong\u003e Robust 30A contacts support heavy-duty \u003cstrong\u003e1-phase motors\u003c\/strong\u003e up to 5 HP.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Supco APR5 compatible with my specific compressor?\u003c\/strong\u003e\u003cbr\u003e\nThe APR5 is a \u003cstrong\u003ewire-to-wire replacement\u003c\/strong\u003e for almost any potential relay. Check your motor specs; if it is a single-phase unit up to 5 HP with a pickup voltage between 130V and 370V, this relay is applicable.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I set the pickup voltage on the APR5?\u003c\/strong\u003e\u003cbr\u003e\nTechnicians should refer to the original relay's specifications. If unknown, typical settings are 180V for 115V systems and 310V for 208\/240V systems. Fine-tuning ensures the \u003cstrong\u003estart capacitor\u003c\/strong\u003e drops out at 70-80% of full motor speed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan this replace a 5-terminal relay?\u003c\/strong\u003e\u003cbr\u003e\nYes, the APR5 is designed to replace both 3-terminal and 5-terminal configurations, providing a streamlined \u003cstrong\u003eHVAC repair\u003c\/strong\u003e solution that reduces the need to carry multiple OEM parts.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
