B315H - 15Amp Circuit Breaker

B315H - 15Amp Circuit Breaker

The Siemens B315H circuit breaker is a solid choice for your three-phase electrical systems that need dependable protection with a higher interrupting rating than standard breakers. Rated at 15 amps for 240V applications, this 3-pole Type BLH breaker helps protect your circuits, wiring, and connected equipment from overloads and short circuits in commercial and industrial environments.

Its 22kA interrupting capacity makes it especially useful in systems where available fault current is higher and extra protection matters. The thermal magnetic trip design responds to both overload conditions and sudden fault events, helping reduce the risk of damage to panels and electrical equipment during everyday operation.

The bolt-on design provides a secure fit in compatible Siemens panelboards and distribution equipment, making installation and replacement work more straightforward. Its compact footprint also helps when working in crowded panelboards or control equipment where available space may already be limited.

The Siemens B315H is commonly used in branch circuits, control panels, OEM equipment, and power distribution systems where reliable three-phase circuit protection is needed without adding unnecessary complexity.
