NOTES
1. BIMETAL 28: R = 4.83 mΩ, τ = Rth·C = 30 s; TRIPS AT f = 0.8 mm, ΔT = 86 K.
2. THERMAL: t = τ·ln(ΔTss / (ΔTss − 86 K)), ΔTss = Rth·R·I². NO TRIP BELOW 21.1 A.
3. MAGNETIC: COIL 21 BEATS SPRING 26 (0.4 N) ABOVE Im = 64 A = 4 In.
4. A RESET HOLDS ONLY WHEN f < 0.64 mm (ΔT < 69 K): OPEN → HALF-OPEN.
5. CRADLE 13, PAWL 14 BEHIND THE PLANE. MOTION SLOWED: A FAULT CLEARS IN ≈ 5 ms.
