Description
The Macromatic GB120A2 is a compact 2-pole general purpose plug-in relay engineered for reliable, cost-effective switching in industrial control circuits, automation panels, and machinery interface applications. Operating on a 120 VAC control supply voltage, this 8-blade terminal relay features high-capacity 2 Form C (DPDT) output contacts rated up to 12 Amps at 250 VAC or 30 VDC.
Housed in a transparent dust cover for easy visual inspection, the GB120A2 includes an integrated LED status indicator for immediate power status confirmation and a manual push-to-test button for straightforward circuit troubleshooting during commissioning. Designed to pair with 8-blade socket bases (such as the Macromatic SB2ZC5 DIN rail/surface mount socket), this lightweight 0.08 lb (36 g) relay delivers an extended mechanical life of 20 million operations across wide operating temperatures from -40°F to 158°F (-40°C to 70°C).
Key Features
- High-Capacity 12A Switching: 2 Form C (DPDT) contact configuration handles switching loads up to 12 A @ 250 VAC / 30 VDC (3000 VA / 360 W maximum capacity).
- Integrated LED & Push-to-Test Button: Front LED provides visible coil power status, while the manual push-to-test button simplifies circuit verification and testing.
- Transparent Protective Cover: Clear housing allows visual inspection of internal contacts and mechanics while protecting components from ambient dust and debris.
- Standard 8-Blade Plug-In Form Factor: Industry-standard 8-blade terminal layout enables fast plug-in installation into DIN-rail or panel-mounted sockets.
- Heavy-Duty Service Life: Built for high reliability with a mechanical lifespan of 20,000,000 operations and an operating range of -40°F to 158°F (-40°C to 70°C).
- Global Standards Compliance: UL and cUL Recognized, CE Marked, and RoHS Compliant.
