Product Description

Siemens 3WT8101-6AA08-5AB2 1000A 3-Pole Withdrawable Air Circuit Breaker 66kA

The Siemens 3WT8101-6AA08-5AB2 is a SENTRON 3WT8 withdrawable Air Circuit Breaker (ACB) designed for high-current low-voltage power distribution and protection applications. The configuration supplied is a 3-pole, Size 1 circuit breaker with a rated current of 1000 A, suitable for operation up to 500 V AC at 50/60 Hz, with an ultimate short-circuit breaking capacity (Icu) of 66 kA at 500 V AC. Siemens' 3WT8 technical catalogue confirms the Size 1 1000 A family is available with 66 kA Icu at 500 V and withdrawable 3-pole configurations.

The withdrawable construction with guide frame makes this type of ACB suitable for switchboards where controlled isolation, inspection, maintenance and breaker replacement are important. The breaker can be moved between connected and withdrawn positions according to the applicable switchgear operating procedure.

The 1000 A rated current makes the 3WT8101-6AA08-5AB2 suitable for high-capacity applications such as main incomers, industrial feeders, generator distribution and large low-voltage switchboards. Correct coordination with busbars, conductors, upstream/downstream protective devices and the actual prospective short-circuit current is essential.

The supplied configuration includes a mechanical lockout device, tripped signalling switch, tripped indicators and guide frame. These functions support controlled operation and breaker-status indication in professional electrical switchgear.

Siemens publicly lists closely related 3WT8 configurations with the same Size 1, 1000 A, 3-pole and 66 kA/500 V electrical platform. However, a directly indexed Siemens record for the exact 3WT8101-6AA08-5AB2 MLFB was not found, so additional MLFB-specific release or control-voltage details have not been assumed.

Benefits

The 1000 A rated current makes the 3WT8101-6AA08-5AB2 suitable for high-capacity low-voltage power-distribution systems where substantial electrical loads require reliable switching and protection.

The 66 kA Icu at 500 V AC provides high short-circuit interruption capability for suitable high-fault-level installations. Siemens' 3WT8 catalogue confirms this interruption rating for the relevant Size 1, 1000 A family. The actual prospective short-circuit current should always be verified before final selection.

The 3-pole construction provides coordinated protection and switching for compatible three-phase AC systems. This makes the breaker suitable for main distribution sections, industrial feeders and high-current three-phase electrical systems.

The withdrawable construction with guide frame provides operational flexibility for switchboard inspection, maintenance and servicing. The breaker can be withdrawn according to the manufacturer's prescribed procedure, supporting controlled isolation and equipment replacement.

The mechanical lockout device supports controlled breaker operation during defined isolation and maintenance procedures.

The tripped signalling switch and tripped indicators provide useful status information for operators and maintenance personnel. These features can help identify a trip condition and simplify troubleshooting during electrical-system restoration.

The Siemens SENTRON 3WT8 series is intended for professional low-voltage power distribution, making this type of ACB suitable for OEMs, EPC contractors, panel builders, electrical contractors, system integrators and industrial maintenance teams.
