50 A C-Curve MCB for Panel Protection
Rated 230 V AC with a breaking capacity of 15 kA per EN 60898 and 20 kA per IEC 60947-2, this MCB is sized for sub-distribution boards where the prospective fault current stays under those thresholds. The 72 V DC maximum rating (per IEC 60947-2, 15 kA) covers control-circuit DC supplies, though the primary application is AC branch protection.
Mounts via the quick-assembly system onto standard DIN rail — 36 mm width (2 width units), 90 mm height, 76 mm depth. Installation depth is 70 mm. Sealable design allows panel-lockout procedures.
Halogen-free and silicon-free construction, suited for sensitive environments like semiconductor fabs or clean rooms where outgassing must be minimized. The MCB is rated for mechanical engineering and industry applications per its suitability designation. Humidity derating applies: max 95% RH up to 55 °C, derating to 55% at 70 °C and 35% at 75 °C — relevant for panels in hot, humid locations.
