Siemens Q315HH 15A 3-Pole 240 V Circuit Breaker

Siemens Q315HH 15A 3-Pole 240 V Circuit Breaker is a compact, reliable protection device for three-phase electrical systems. With a 15-ampere rating and 240-volt operation, this part (Q315HH) is designed to safeguard branch circuits against overloads and short circuits while keeping wiring neat and compliant in Siemens panels.

Designed to handle three-phase distribution, the 3-pole configuration provides synchronized protection across all phases, preventing unbalanced loads that can damage motors and equipment. This makes it an ideal choice for commercial and light industrial applications where three-phase power is standard, such as HVAC, pumps, conveyors, or machine controls.

Why choose the Siemens Q315HH?

• Precise three-phase protection: Each of the three poles carries current up to 15 A, with a single trip action that shuts down all phases to prevent damage from faults.
• Straightforward compatibility: Part Number Q315HH fits compatible Siemens panels that accept 3-pole, 240 V breakers, simplifying replacement and maintenance.
• Clean, reliable operation: Built to perform consistently in typical panel environments, helping reduce nuisance trips and extend the life of connected equipment.
• Space-conscious design: A compact 3-pole unit that integrates neatly into standard distribution panels without excessive ducting or spacing.
• Clear electrical protection for three-phase systems: A dedicated solution for distributing 3-phase power safely and effectively.

Use cases and scenarios

Install the Q315HH in new installations or panel upgrades where a 15 A, 3-pole, 240 V breaker is required. It's well-suited for protective devices feeding three-phase motors, fans, pumps, or automated equipment in offices, data centers, workshops, or light manufacturing facilities.
