Square D HLA36070SVYP 70A 3-Pole 600 V Circuit Breaker Potential Transformer

Meet the Square D HLA36070SVYP — a purpose-built 70 A, 3‑pole, 600 V circuit breaker designed for demanding industrial power systems. This model couples rugged protection with built‑in potential transformer features, enabling reliable current interruption while supporting modern monitoring and protection schemes.

Key features that matter in the field

• 70 A current rating provides robust protection for large three‑phase feeders and motors, helping prevent expensive equipment damage from overloads and faults.
• 3‑pole configuration ensures synchronized protection across all three phases, reducing imbalance risk and improving overall system reliability in 3‑phase networks.
• 600 V maximum voltage rating makes this unit suitable for industrial distribution, process lines, and commercial power systems that demand higher voltage protection.
• Potential transformer integration supports measurement, metering, and protection relays, delivering usable signals for SCADA, energy management, and relay coordination without extra adapters.
• Trusted Square D engineering delivers consistent performance, documented compatibility with protection schemes, and streamlined servicing in maintenance routines.

Why this model stands out

Unlike basic breakers, the HLA36070SVYP is designed with measurement-friendly capabilities that align with modern electrical protection architectures. By pairing sturdy, fast‑acting fault interruption with a potential transformer interface, you gain clearer visibility into system health and more precise relay triggering. This combination reduces nuisance trips, simplifies fault diagnosis, and supports more accurate energy metering for ongoing optimization of your facility’s electrical load.

Ideal use cases

• Industrial facilities with heavy three‑phase motors and conveyors needing dependable protection at the 70 A range.
• Motor control centers and power distribution panels where monitoring and protection must co-exist in a compact footprint.
• Data centers and manufacturing lines that require reliable fault interruption along with integratable metering signals for monitoring systems.
