Operating temperature range -40 °C to +75 °C, with humidity derating: max 95% RH at 55 °C, tapering to 35% RH at 75 °C.
Halogen-free and silicon-free construction. Sealable for tamper-proofing. Polarity must be observed on the DC supply (position of power supply cord: consider polarity).
10 kA at 220 V DC per IEC 60947-2, with a maximum DC operating voltage of 250 V.
Both share the same 18 mm width, 76 mm depth, 90 mm height, and DIN-rail mounting, so the physical fit is identical. The key difference is that the 5SY5103-7CC11 is rated for DC railway applications (220 V DC, 10 kA) while the 5SY4116-7CV is an AC-rated part (230 V AC, 15 kA) for mechanical engineering. Verify the supply voltage type before substituting.
