Hartland Controls 90342 Relay
The Hartland Controls 90342 Relay is a heavy-duty DPDT 240V relay designed for demanding HVACR switching applications. Engineered as a general purpose switching relay, this double pole double throw component provides isolated control for multiple circuits, making it a standard replacement for HVAC fan relays and motor internal switching. Featuring a 208/240 VAC coil with a nominal resistance of 1600 Ohms, the 90342 is built to withstand the high inrush currents typical of commercial refrigeration and residential air conditioning systems. The Class B insulation system and silver cadmium oxide alloy contacts ensure long-term arc resistance and reliable electromechanical switching performance across a wide temperature range from -55?C to 125?C. With a multi-positional mounting bracket and standard .250 inch QC terminals, this relay offers versatile installation for technicians in the field, compatible with many cross-references from White-Rodgers (90-342), Packard (PR342), and Mars.
Key Benefits- High Current Rating: Handles up to 15A resistive at 277 VAC and 12 FLA at 120 VAC for robust load management.
- Universal Compatibility: Direct cross-reference for common industry part numbers including Mars 90342 and White-Rodgers 90-342.
- Durable Construction: Features a mechanical life expectancy of 1,000,000 operations and UL 508 certification for safety standards.
- Efficient Installation: Integrated mounting bracket and quick connect terminals minimize downtime during component replacement.
What is the difference between a DPDT and SPDT relay in HVACR?
A DPDT 240V relay like the 90342 features two separate sets of contacts that move simultaneously, allowing a single coil signal to control two independent circuits at the same time, whereas an SPDT only controls one.
Can I use the 90342 relay for both 208V and 240V systems?
Yes, the 208/240 VAC coil is specifically rated to operate within the voltage range of 208V to 240V systems commonly found in HVAC/R solutions.
Is the Hartland Controls 90342 suitable for fan motor control?
Absolutely. It is frequently utilized as a switching fan relay, rated for up to 3/4 HP at 120 VAC, making it ideal for blower motors and condenser fans.
