Square D HGL36090AABCSH 36090A 3-Pole 600 V Circuit Breaker Potential Transformer

Introducing the Square D HGL36090AABCSH — a robust 3‑pole, 600 V circuit breaker with integrated potential transformer designed for demanding electrical environments. This model, part number HGL36090AABCSH, blends precise voltage sensing with reliable overcurrent protection, delivering a compact solution that simplifies protection and metering tasks in one unit.

What makes this design stand out

• Integrated potential transformer provides accurate voltage sensing for protective relays and metering, reducing the need for separate sensing components and simplifying panel wiring.
• Three-pole configuration supports balanced protection across all phases (L1, L2, L3), helping maintain system stability in three‑phase power networks.
• 600 V maximum system voltage paired with a substantial current rating to handle demanding industrial loads while preserving protective coordination.
• Factory‑built reliability from Square D ensures compatibility with standard switchgear and panels, enabling smoother installations and replacements in existing setups.

Why this matters in real-world setups

In manufacturing floors, data centers, and large facilities, you need protection that doesn’t complicate your protection scheme. The HGL36090AABCSH combines circuit protection with voltage sensing in one unit, cutting down wiring complexity and installation time.
