It occupies three modular slots on the DIN rail and provides a separate trip coil for the upstream circuit breaker when leakage current is detected. ## Dimensions and wiring The accessory measures 31.2 mm deep, 21.7 mm wide, and 65.1 mm high. The stripped length for the connecting conductors is 10 mm (0.4 in). These dimensions match the standard SENTRON modular envelope, so it clips directly onto the same DIN rail as the RCD without extra panel space.","metaTitle":"Siemens SENTRON 3VA9988-0BR10 Residual Current Release, 3 Sl","metaDescription":"Siemens SENTRON 3VA9988-0BR10 residual current release (RCR) accessory for RCD310 or RCD510.
