It draws 0.1 A max from the breaker's electronic trip unit supply, losing 2.4 W, and communicates switch position (On, Off, Tripped) plus data from the trip unit and residual-current equipment over a spur-line T-feeder interface. The 4-slot module supports up to 20 m total system length on the circuit-breaker communication bus. ## Fit and environmental limits Dimensions are 29 mm wide × 63 mm high × 33 mm deep — it lives inside the breaker pocket, not on the DIN rail, so it doesn't eat panel width. Rated IP20 (fingers, not water), pollution degree 3 (conductive or dry non-conductive pollution), overvoltage category I. Protection class III per IEC 61558 means it's supplied from a safety extra-low voltage source.","metaTitle":"Siemens 3VA9177-0TB10 COM060 Communication Module, 4 Slots,","metaDescription":"Siemens SENTRON 3VA9177-0TB10 COM060 communication module for 3VA6 150/250 breakers. 4 slots, 0.1 A max draw, 2.4 W loss, IP20.
