It occupies one modular width (18 mm) on a DIN rail, mounts in any position, and is IP20 rated with conductors connected. Thermal derating is baked into the spec: at 40 °C ambient the continuous rating drops to 8.89 A, at 50 °C to 7.6 A, and at 55 °C to 6.91 A. ## Panel integration Sealable — the toggle can be locked in the OFF position for lockout/tagout compliance.","metaTitle":"5SY4110-7CV MCB 1-pole C-curve 10 A 15 kA IEC/EN 60947-2","metaDescription":"5SY4110-7CV miniature circuit breaker, 1-pole, C-curve, 10 A rated, 15 kA breaking capacity per IEC/EN 60947-2.
