Product Description

Siemens 3WT8326-6UP16-5AB2 Withdrawable Circuit Breaker 3200A, 4-Pole, 66kA

Product Description

The Siemens 3WT8326-6UP16-5AB2 is a high-capacity Siemens SENTRON 3WT8 withdrawable circuit breaker designed for demanding industrial and power distribution applications. This 4-pole circuit breaker is rated up to 3200 A and is suitable for electrical systems up to 500 V AC at 50/60 Hz.

With a 66 kA ultimate short-circuit breaking capacity (Icu) at 500 V, the breaker is designed for applications where high fault-current interruption capability is required. Its withdrawable construction allows the circuit breaker to be positioned within a compatible guide frame, supporting convenient installation, inspection, maintenance and replacement in switchgear assemblies.

The breaker includes a mechanical lockout device, tripped signaling switch and tripped indicators, providing additional operational status and locking functionality for demanding low-voltage switchgear applications.

This Siemens 3WT8 circuit breaker is suitable for industrial power distribution, large electrical panels, infrastructure projects, manufacturing facilities, commercial buildings and high-capacity switchboards.
