Key Features

• 50 A continuous current rating (240 VAC)
• 3‑pole design for three‑phase protection
• Bolt‑on molded case construction
• 10 kA interrupting rating

What this breaker does

The Siemens B350 provides overcurrent protection for three‑phase circuits. As a 3‑pole molded case circuit breaker, it opens all three poles when a fault condition requires interruption, protecting conductors and connected equipment.

• Designed for use in three‑phase 240 VAC distribution systems.
• Interrupts fault currents up to the rated interrupting capacity (10 kA).

Electrical ratings and limits

Use the breaker only within its published electrical limits. The B350 is specified for 50 amps at 240 VAC and has a 10,000 ampere interrupting rating (10 kA). These are the defining electrical characteristics for evaluating compatibility with your panel and load.

• Continuous current rating: 50 A
• Voltage rating: 240 VAC
• Interrupting rating: 10 kA

Mounting and physical style

The B350 is a bolt‑on style molded case circuit breaker. Bolt‑on breakers secure to the panel or equipment with mounting bolts rather than plug‑in or draw‑out methods; ensure the panel is designed to accept bolt‑on MCCBs of this style.

• Molded case construction for surface insulated poles
• Bolt‑on mounting—confirm panel compatibility
