Siemens B360HH - 60 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens B360HH 60A, 240V, 3-Pole Bolt-On Molded Case Circuit Breaker—the robust protection your electrical panel needs for reliable, trouble-free operation. Built to shield branch circuits from overcurrent and short circuits, this unit is tailored for panelboards and load centers in residential, commercial, and light industrial environments.

Why this bolt-on design matters

• Secure bolt-on mounting delivers a rigid, vibration-resistant bus connection. In spaces with equipment movement or vibration, this design helps prevent loose connections that can lead to arcing or nuisance trips.
• Thermal-magnetic trip unit provides stable, repeatable protection performance across varying loads. The thermal element responds to sustained overcurrent, while the magnetic element delivers a fast, decisive trip for short circuits, helping protect both wiring and connected equipment.
• OEM-compatible for seamless integration is designed to work with matching Siemens OEM load centers and panelboards, ensuring straightforward installation and consistent electrical characteristics across your panel system.

Key benefits and practical use cases

The B360HH is ideal for three-phase circuits where dependable protection is essential. Use it to safeguard motor control circuits in light industrial setups, three-phase lighting and power distribution in commercial spaces, or residential multi-wire branch circuits that require solid overcurrent protection. Its 60A rating makes it a practical choice for medium-duty equipment—balancing protection with the ability to handle normal startup surges typical of fans, compressors, and similar loads.

What problems it solves

• Prevents electrical fires and equipment damage by interrupting fault currents quickly and reliably.
• Reduces downtime with solid, repeatable protection that minimizes unexpected trips due to transient conditions.
• Streamlines maintenance and upgrades by matching Siemens panel systems, reducing compatibility concerns.
