Siemens HHED63B035L - 35 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Siemens HHED63B035L is a 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. At 35A and 600V, it provides robust protection for a range of commercial and light industrial applications, while still being suitable for residential panel upgrades where three-phase protection is required.

Why this breaker stands out

• Secure bolt-on mounting delivers a rigid, vibration-resistant bus connection that stays solid through equipment startup, heavy loads, and equipment vibrations.
• Thermal-magnetic trip unit combines precise overload sensing with instantaneous magnetic trip for fast, repeatable protection against short circuits.
• OEM-loadcenter compatibility is built to match Siemens' own panels and compatible loadcenters, enabling straightforward replacements and coordinated protection schemes.
• 3-pole, 600V rating makes it ideal for three-phase circuits common in commercial and light industrial environments, including motor loads, fans, and distributed power systems.

Who benefits most

Electrical contractors, facilities maintenance teams, and installers working on panel refurbishments or new builds will appreciate the predictability and ease of installation this breaker offers. It’s a practical choice for residential projects requiring three-phase protection, or small-to-mid size commercial and light industrial installations needing reliable branch circuit protection with a compact, bolt-on format.

Performance and protection in everyday scenarios

• : Provides dependable protection for three-phase motor starters and feeders, helping avoid nuisance trips while safeguarding conductors and equipment.
