Siemens 3WT8326-6UN34-5AB2 Withdrawable Circuit Breaker 3200A, 4-Pole, 66kA

Product Description

The Siemens 3WT8326-6UN34-5AB2 is a high-capacity Siemens SENTRON 3WT8 withdrawable circuit breaker designed for reliable protection and switching in demanding industrial and power distribution systems.

This 4-pole, Size 2 circuit breaker has a rated current of 3200 A and is designed for systems up to 500 V AC, 50/60 Hz. With an ultimate short-circuit breaking capacity (Icu) of 66 kA at 500 V, it is suitable for high-fault-level electrical installations where robust circuit protection is required.

The withdrawable design, combined with a guide frame, makes the breaker suitable for switchboards where convenient inspection, maintenance and replacement are important. The included mechanical lockout device, tripped signaling switch and tripped indicators provide additional control and status indication capabilities.

It is an ideal choice for industrial switchboards, large power distribution panels, manufacturing plants, infrastructure projects and high-capacity electrical systems.
