Hubbell HBL400FR 400A 600V Single Pole Device

The Hubbell HBL400FR is a high-current, 400 A, 600 V single-pole device from Hubbell. Designed for electrical installations that require a single-point interruption, the HBL400FR delivers a dependable 400 ampere rating while supporting system voltages up to 600 volts. With its single-pole configuration, this device interrupts or isolates a single conductor in a circuit, providing a straightforward means of disconnection in power distribution paths. The HBL400FR designation specifies the exact model and its electrical specifications, helping engineers and technicians verify they are using the intended part in the correct application. In contexts where a dedicated, single-pole solution is needed to control or isolate a circuit leg, the HBL400FR's 400 A at 600 V rating defines its suitability for high-current, lower-voltage segments within a broader electrical system. From Hubbell, the HBL400FR is a model-specific option for projects requiring a single-pole device with clear, model-based ratings.
