Blue Sea Battery Switch – e-Series 350A 4 Way Isolator – 9001EB

Blue Sea Systems e-Series 9001e 1/2/1+2/OFF marine battery selector & combiner switch for use with inboard petrol and diesel engines. This switch has a 350A continuous current rating, a maximum cranking/starting rating of 1200A for 30 secs and a voltage rating of 32V DC, making it suitable for use with 12V & 24V systems.

The 1/2/1+2/OFF battery selection & combining configuration allows switching between batteries (or banks of batteries) and allows the batteries to be combined in parallel for charging or emergency starting. The make-before-break contact design ensures that power is uninterrupted when switching between battery banks, and this switch is useful for disconnecting the batteries in emergencies or when the vessel is not in use.

The e-Series range of battery switches are engineered for use in harsh marine environments in applications requiring high power output, high reliability, and low heat generation. The M10 (3/8″) tin-plated copper terminal studs provide maximum conductivity and corrosion resistance, and their 22mm length allows multiple cable terminals to be connected. The studs are a one-piece design, meaning they cannot work loose over time and the risk of over heating is reduced.

The ignition-protected case design is standardised across the range and has an IP66 waterproof rating, can accept cables up to 120mm² (4/0 AWG) in cross-section, and can be surface or rear panel mounted. The design of the actuating knob includes raised features that allow the position of the switch to be determined by feel – useful if operating in confined spaces.
