Product Description

Siemens 3WT8165-6AG08-5BC2 – Air Circuit Breaker (ACB)

The Siemens 3WT8165-6AG08-5BC2 is a SENTRON 3WT8 series Air Circuit Breaker (ACB) used for high-capacity low-voltage power distribution systems in PCC, MCC, transformer and generator panels.

It belongs to the 1600A frame (3WT8165 family) and is designed for industrial-grade fault protection with high short-circuit breaking capacity (typically up to 66 kA class at 500V AC depending on configuration).

🔹 Description

The Siemens 3WT8165-6AG08-5BC2 is a draw-out type ACB (Air Circuit Breaker) used for protecting and controlling large electrical systems. It provides protection against:

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

It uses an electronic microprocessor-based trip unit (ETU37WT family) for precise and adjustable protection settings.

👉 Simple meaning:
Ye 1600A class ka industrial main breaker hai jo heavy fault current ko safely isolate karta hai aur system ko protect karta hai.
