The L115F1 Series latching relay boasts the ability to withstand heavy contact load with strong shock and vibration resistance. Offering up to 50A and UL/cUL approved, the CIT Relay & Switch relay is suited to energy smart applications.

The 1A, 1B and 1C contact arrangements have contact ratings of 30A, 40A and 50A @ 277VAC. Contact resistance is less than 50mΩ, with the contact material being either AgSnO2 or AgSnO2In2O3. Tested electrical life of the L115F1 Series is 50k cycles with mechanical life of 1M cycles. The dielectric strength is 2500Vrms minimum coil to contact and 1500Vrms minimum contact to contact. 

Insulation resistance is 1000Ω minimum at 500VDC. Shock resistance is 200m/s2 for 11 ms and vibration resistance is 1.5mm double amplitude 10~40Hz. Weighing 28g or 20g no cover, operating temperature is -55°C to 125°C and solderability is 270°C for 5s.
