Product Description

Siemens 3WT8101-6AA04-5AB2 1000A 3-Pole Withdrawable Air Circuit Breaker 66kA

The Siemens 3WT8101-6AA04-5AB2 is a SENTRON 3WT8 withdrawable Air Circuit Breaker (ACB) designed for high-current low-voltage power distribution and protection applications. It 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. The specified ultimate short-circuit breaking capacity (Icu) is 66 kA at 500 V AC. Siemens and corresponding technical documentation identify this exact MLFB with an ETU37WT LSING electronic overcurrent release with display.

The breaker uses a manual draw-out (MDO) withdrawable construction with guide frame, making it suitable for switchboards where inspection, servicing, isolation and breaker replacement are important. The exact product documentation also specifies a mechanical lockout device, tripped signalling switch, tripped indicators, 2-piece shutter with sealing cap and door sealing frame.

The ETU37WT LSING overcurrent release provides electronic protection for overload, short-circuit and earth-fault conditions, with a display and setting range according to the selected frame size. The exact product listing identifies the breaker as a 1000 A, 3-pole, 66 kA, manual draw-out ACB with ETU37WT protection.

The 1000 A rated current makes this ACB suitable for high-capacity electrical distribution applications including main incomers, industrial feeders, generator distribution systems and large low-voltage switchboards. The actual load current, busbar rating, prospective short-circuit current and protection coordination should always be evaluated before installation.

Technical Specifications

The technical documentation for the exact MLFB identifies 3 poles, Size I, 1000 A, 500 V rated operational voltage and 66 kA short-circuit breaking capacity.

Benefits

The 1000 A rated current makes the 3WT8101-6AA04-5AB2 suitable for high-capacity low-voltage distribution systems where substantial electrical loads require dependable switching and protection.

The 66 kA Icu at 500 V AC provides high short-circuit interruption capability for suitable high-fault-level installations. The exact product documentation confirms this rating for the 3WT8101-6AA04-5AB2.

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

The manual draw-out design with guide frame provides operational flexibility for switchboard maintenance and inspection. The breaker can be withdrawn according to the manufacturer's prescribed procedure, supporting controlled isolation and servicing.

The ETU37WT LSING electronic overcurrent release with display provides electronic protection and monitoring for overload, short circuit and earth-fault conditions. This makes the ACB suitable for applications where adjustable electronic protection is required.

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.

The 2-piece shutter with sealing cap and door sealing frame support controlled access to the breaker compartment and organized switchgear integration.
