Power Relay G7L-PV Two-pole Power Relay That Is Ideal for Inverters in Photovoltaic Power Systems High switching capacity with contact rating of 30 A at 280 VAC (AC7a class). Power consumption reduced by lowering coil voltage after relay operation (low power consumption of approx. 320 mW at 37.5% reduced coil voltage). Ambient operating temperature of up to 85 C. Contact gap of 3.0 mm for safety. UL and VDE class F certification for coil insulation.
