SIEMENS 3VT4710-3AA30-0AA0 SENTRON 3VT MOLDED CASE CIRCUIT BREAKER MCCB

SIEMENS 3VT4710-3AA30-0AA0 is a 3-pole MCCB from Siemens SENTRON 3VT series, rated 1000A, operational voltage up to 690V AC, high breaking capacity Icu=65kA@415V AC, designed for low voltage main switchboard and feeder protection. The circuit breaker is supplied without electronic trip unit, auxiliary switch and shunt release, users can match thermal-magnetic or electronic trip units according to protection requirements. The circuit breaker delivers overload, phase imbalance and short-circuit protection for generators, main feeders, large motor groups and marine power distribution circuits. The circuit breaker supports optional add-on accessories including auxiliary contact, alarm contact, under-voltage release, shunt trip and motor operator for remote status feedback and remote tripping to ship alarm & automation systems. The circuit breaker adopts modular mechanical structure, easy to assemble accessories on site.

SIEMENS 3VT4710-3AA30-0AA0 is fitted inside LV switchboard compartment, front IP40 protection rating. The power distribution MCCB complies with IEC 60947-2 standard, insulation voltage 800V AC. The power distribution MCCB has mechanical life of 25,000 operations and electrical endurance 10,500 cycles at 690V AC. The power distribution MCCB is robustly constructed to withstand vibration, humidity and temperature fluctuation, suitable for marine, offshore and heavy industrial power distribution cabinets. The power distribution MCCB is a discontinued legacy model; its successor is Siemens 3VA series MCCB.

SIEMENS 3VT4710-3AA30-0AA0 is widely deployed on cargo ships, tankers and offshore platforms for main busbar, generator feeder and large auxiliary power branch protection systems. The industrial spare part can replace defective MCCBs to restore low voltage power distribution overload and short-circuit protection rapidly. The industrial spare part matches original mechanical mounting dimensions and busbar/wiring specifications for direct cabinet installation replacement. The industrial spare part has clear part marking for fast identification and stock management. The industrial spare part reduces system downtime during switchboard overhaul and marine survey inspection.
