Siemens BE240 - 40 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens BE240 is a robust 2-pole, 40A, 240V bolt-on molded-case circuit breaker engineered to deliver dependable branch circuit protection in panelboards and load centers. Built for endurance, this BE240 combines a secure bolt-on mounting with a precise thermal-magnetic trip unit, ensuring stable protection across everyday electrical demands in residential, commercial, and light industrial settings.

Key benefits that stand out

• Secure bolt-on mounting: Provides a rigid, vibration-resistant bus connection that maintains consistent electrical contact even in busy, vibration-prone environments.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by responding to both overloads (thermal) and short circuits (magnetic) for reliable circuit safeguarding.
• 2-pole, 40A at 240V: Protects two conductors simultaneously, ideal for protecting shared loads and essential circuits in panels.
• Molded-case construction: Durable, long-lasting housing designed to withstand regular switching and electrical load cycles.
• OEM compatibility: Engineered to work with matching Siemens OEM load centers and panelboards for seamless upgrades and hassle-free installation.

Ideal applications and use cases

This BE240 is well-suited for:

• Residential service panels supplying critical circuits like HVAC, water heating, and lighting, where reliable protection matters most.
• Commercial panels powering small office or retail lighting and receptacle branches, offering quick replacement and predictable performance.
• Light industrial panels and control circuits in workshops that demand a rugged, bolt-on solution to minimize downtime from tripped circuits.

What makes it different from other breakers

Unlike generic alternatives, the Siemens BE240 emphasizes a secure physical connection and predictable protection behavior. The bolt-on mounting reduces movement that can lead to loose connections over time, while the thermal-magnetic trip unit provides fast, coordinated response to faults without sacrificing nuisance trips during routine overloads. Its OEM compatibility means fewer compatibility questions during panel upgrades or replacements.
