Hartland Controls SPNO General Purpose Relay

The Hartland Controls SPNO general purpose relay (single pole, normally open switching relay) controls a circuit with a low-power signal. When the coil is energized, an electromagnetic current closes the contacts and completes the circuit. These relays are a common choice for HVAC systems, standby power supplies and telephone exchanges. They are also called fan relays or general purpose switching relays.

Key Features:

• Single pole, normally open (SPNO) switching configuration
• Double-make contact configuration
• Silver cadmium oxide alloy contacts for dependable switching
• .250" quick-connect (QC) terminals for power pole and coil connections
• Class B insulation system
• Multi-positional mounting
• Conforms to UL 508 (File No. E227250)
• Rated for 1 million mechanical operations
• Operating temperature range of -40°C to +65°C

Hartland Controls builds its relays in the USA. They are available in several coil voltage options so you can match the relay to your control circuit. They suit HVAC equipment, standby power and other general switching jobs.
