Information About B270
The B270 is part of Siemens’ BL Series, a line of bolt-on breakers engineered for low-voltage distribution applications requiring stable and consistent protection. Its 2-pole configuration supports 240-volt single-phase circuits commonly used for medium-load equipment. The breaker incorporates LI (long-time and instantaneous) trip functions, enabling accurate response to both gradual overload conditions and sudden short circuits. With a 10 kA interrupt rating at 240 V, the B270 safely handles typical residential and commercial fault levels, making it a dependable solution for branch-circuit protection.
Key Features:
- 70A, 240V rating: Supports medium-demand single-phase loads.
- 2-pole configuration: Provides full disconnect capability for 240-volt circuits.
- Thermal-magnetic trip unit: Protects against overloads and instantaneous faults.
- LI protection functions: Offers long-time and instantaneous trip characteristics.
- Bolt-on mounting: Ensures secure and stable installation in BL Series panels.
- 10 kA interrupt rating: Suitable for standard residential and commercial fault-current conditions.
- BL Series design: Compatible with widely used Siemens/ITE load centers.
The B270 delivers the reliability and precision required for molded case circuit protection in residential and commercial single-phase systems.
