Product Description

Siemens 3WT8165-6AN04-5AB2 – Air Circuit Breaker (ACB)

The Siemens 3WT8165-6AN04-5AB2 is a SENTRON 3WT8 series Air Circuit Breaker (ACB) used for low-voltage high-capacity power distribution systems such as PCC, MCC, transformer and generator feeder panels.

It belongs to the 1600A frame (3WT8165 family) and is designed for high fault level protection and safe isolation of industrial electrical networks.

🔹 Description

The 3WT8165-6AN04-5AB2 is a withdrawable type ACB used in heavy electrical systems where reliable switching and fault protection is required.

It provides protection against:

• Overload conditions
• Short circuit faults
• Earth fault protection (depending on trip unit configuration)

It uses an electronic microprocessor-based trip unit (ETU series – LSING/LSI type depending on variant) for accurate and adjustable protection settings.
