63 A MCCB with high interrupting capacity for line protection
Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the 187 kA figure at 240 V means it can safely clear a fault on a high-capacity transformer secondary without the arc re-striking, a critical spec for main breaker applications where fault current is highest.
Panel fit and auxiliary configuration
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard SENTRON 3VA frame size that fits existing 3VA panel cutouts and busbar arrangements. The breaker ships with the basic switch 3VA21635HL320AA0 and is configured for 4 auxiliary switches (HQ type), providing status feedback for PLC inputs or remote monitoring without needing an add-on module.
