Active production — what that means for your BOM line
The RM4JA01F: No stock-holding claim — quoted per BOM quantity.
What the measurement range covers — and where it fits
Output is a single changeover contact (1 C/O) rated 250 V AC switching voltage, with 90/10 silver-nickel contacts good for 30 million mechanical cycles. The relay trips when measured current exceeds the set threshold — no built-in time delay, so it's a straight overcurrent alarm or trip relay for applications where instantaneous response is required.
DIN-rail footprint and environmental fit
Occupies 2.5 DIN-module pitches on the rail — 23 mm wide, 80 mm deep, 78 mm tall. Screw terminals accept 2 x 1.5 mm² flexible with ferrule or 2 x 2.5 mm² without; tightening torque is 0.6–1.1 N·m. IP20 at the terminals, IP50 on the casing — suitable for clean indoor panel environments, not washdown zones. Rated pollution degree 3 per IEC 60664-1, dielectric test voltage 2.5 kV, and non-dissipating shock wave withstand of 4.8 kV. Shock resistance is 15 gn for 11 ms per IEC 60255-21-1 — holds up in industrial panel vibration without contact chatter.
