When access is tight, I leave a Fluke on Min/Max across the 125 VDC control bus during the planned outage window. The last time a breaker “only failed when I left,” it caught a 2 V dip when the spring‑charging motor started in a “sudden cold snap,” just enough to nudge the undervoltage relay. Do you have any DC bus min/max numbers from your site?
I clip a two-channel recorder — one lead on the close coil, the other on 52a — to see coil voltage against aux timing; the last time it “only failed when I left,” the late 52a pointed to anti-pump chatter from a sticky spring-charge limit switch. You seeing a delayed 52a on cold starts, @amejohn?
Different angle: I put a DC clamp with inrush capture on the close‑coil lead and video the display; if the inrush is soft or about 30% low in the cold, I bypass the control switch/test plug with a temporary jumper to prove a high‑res contact rather than a bad coil — quick to undo. If you don’t have inrush capture, a small shunt with a pocket logger does the same. @jayden_harris98, ever see a ‘flat’ inrush shape nail the culprit?
I’ve had cold snaps turn the spring‑charge into molasses, . I stick a short-term logger on the spring‑charge motor current and a temp probe in the cabinet during the “planned outage window”; if the charge time stretches 2–3x or current plateaus, it’s lube/heat, not the DC supply. @Jess, are your remote yards showing long charge cycles before the miss?
