Siemens B360 60A 3P 240V Circuit Breaker, Bolt-On | AmpState

Meet the Siemens B360 — a 60A, 3-pole, 240V bolt-on circuit breaker designed for panelboards, load centers, and electrical distribution systems. This part is a smart choice for maintenance teams, panel builders, and spare inventory where a direct part-number match matters.

Key benefits of choosing the Siemens B360

• Bolt-on mounting for a secure, reliable fit in compatible Siemens enclosures, enabling quicker installations and fewer alignment issues.
• 60 ampere capacity to protect feeders and branch circuits from overloads while supporting robust 3-phase distribution.
• 3-pole design provides simultaneous disconnection of all active conductors, enhancing safety during fault conditions.
• 240V rating tailored for typical commercial and light industrial distribution panels.
• Direct part-number match with the B360 ensures compatibility in existing installations and simplifies stocking decisions.
• Availability through AmpState, making it easier to source and plan replacements or inventory with confidence.

Practical use cases

• Replacing a failed 60A, 3P 240V breaker in Siemens panelboards or load centers to restore protected circuits quickly.
• Maintaining ready-to-go spare inventory with a clearly identifiable part-number (B360) to minimize downtime during maintenance windows.
• New installations where a 60A, 3-pole, 240V bolt-on breaker is specified by the electrical design or panel schedule.
• Retrofit projects in industrial settings that require reliable, code-compliant circuit protection for 3-phase distribution.

Why this breaker stands out

The Siemens B360 combines dependable protection with a mounting style that stays secure under service conditions. The bolt-on design reduces processing steps during panel assembly and service calls, while the 60A rating provides clear protection boundaries for feeders and motor circuits. A 3-pole configuration ensures safe, coordinated disconnection across all conductors, which is essential for safe startup and maintenance in 3-phase systems.
