At 240 V it interrupts 52.5 kA; at 415 V that drops to 32 kA, and at 690 V to 7.5 kA — the breaking capacity falls as line voltage rises, which is typical for this class. Current derating is minimal up to 50 °C — still 50 A — then drops 1 A per 5 °C step through 70 °C, where it holds 45 A. If your panel ambient runs above 50 °C, the effective ampacity is 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. That 70 °C operating maximum matches the upper end of the operating temperature range. The auxiliary contact version ships as two HQ auxiliary switches (3VA9608-0BB24). No ground-fault monitoring, no N-conductor protection, no phase-failure detection — this is a straight line-protection device. Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — a standard SENTRON 3VA footprint that drops into existing 3VA panel cutouts and bus-bar arrangements without rewiring. The 4-pole format covers three-phase-plus-neutral or three-phase-plus-switched-neutral configurations. The undervoltage release trips the breaker on loss of control voltage, which is the typical setup for emergency-off or undervoltage protection in motor control centers.","metaTitle":"3VA1050-2ED42-0CC0 SENTRON MCCB, 50 A, 4-Pole, 52.5 kA at 24","metaDescription":"Siemens SENTRON 3VA1050-2ED42-0CC0 molded case circuit breaker, 50 A rated continuous current, 4-pole, breaking capacity 52.5 kA at 240 V AC.
