Hager SBN380 Modular Isolator Switch 3P 80A
The Hager SBN380 is a professional-grade 3-pole modular isolator switch engineered to provide secure electrical circuit disconnection in various power distribution systems. Designed for reliability and safety, this device allows for the manual isolation of circuits, which is essential during maintenance or emergency procedures. Its compact modular design fits seamlessly into standard DIN rail enclosures, making it a versatile choice for both industrial and residential electrical panels.
This isolator switch offers robust construction and high operational reliability, ensuring long-term performance in demanding electrical environments. The 3-pole configuration allows for simultaneous disconnection of three phases, providing comprehensive safety for downstream equipment and personnel. Its modular design simplifies the installation process within standard distribution boards, while the high-quality materials used in its manufacturing guarantee durability and consistent electrical contact over time.
This device is not intended for use as a circuit breaker or for protection against overcurrent and short-circuit conditions. It does not provide automatic tripping functions and should always be installed in conjunction with appropriate protective devices like fuses or miniature circuit breakers.
The Hager SBN380 should be installed by a qualified electrician in accordance with local electrical regulations. It is mounted onto a standard DIN rail within a distribution board. Once installed, the switch is operated manually via the front-facing toggle handle to connect or disconnect the power supply to the downstream circuit. Ensure that the terminals are tightened to the manufacturer's specified torque settings to prevent overheating.
Always perform a visual inspection of the switch before and after operation to ensure the handle moves freely and the casing is free of damage. Ensure that the circuit is de-energized before performing any maintenance on the downstream equipment.
